-<p>This section describes the general concepts of the bitcode file
-format without getting into specific layout details. It is recommended
-that you read this section thoroughly before interpreting the detailed
-descriptions.</p>
+
+<p>
+What is commonly known as the LLVM bitcode file format (also, sometimes
+anachronistically known as bytecode) is actually two things: a <a 
+href="#bitstream">bitstream container format</a>
+and an <a href="#llvmir">encoding of LLVM IR</a> into the container format.</p>
+
+<p>
+The bitstream format is an abstract encoding of structured data, very
+similar to XML in some ways.  Like XML, bitstream files contain tags, and nested
+structures, and you can parse the file without having to understand the tags.
+Unlike XML, the bitstream format is a binary encoding, and unlike XML it
+provides a mechanism for the file to self-describe "abbreviations", which are
+effectively size optimizations for the content.</p>
+
+<p>This document first describes the LLVM bitstream format, then describes the
+record structure used by LLVM IR files.
+</p>
+
+</div>
+

+<!-- *********************************************************************** -->
+
+<div class="doc_text">
+
+<p>
+The bitstream format is literally a stream of bits, with a very simple
+structure.  This structure consists of the following concepts:
+</p>
+
+<ul>
+<li>A "<a href="#magic">magic number</a>" that identifies the contents of
+    the stream.</li>
+<li>Encoding <a href="#primitives">primitives</a> like variable bit-rate
+    integers.</li> 
+<li><a href="#blocks">Blocks</a>, which define nested content.</li> 
+<li><a href="#datarecord">Data Records</a>, which describe entities within the
+    file.</li> 
+<li>Abbreviations, which specify compression optimizations for the file.</li> 
+</ul>
+
+<p>Note that the <a 
+href="CommandGuide/html/llvm-bcanalyzer.html">llvm-bcanalyzer</a> tool can be
+used to dump and inspect arbitrary bitstreams, which is very useful for
+understanding the encoding.</p>

+A bitstream literally consists of a stream of bits.  This stream is made up of a
+number of primitive values that encode a stream of unsigned integer values.
+These
+integers are are encoded in two ways: either as <a href="#fixedwidth">Fixed
+Width Integers</a> or as <a href="#variablewidth">Variable Width
+Integers</a>.

+<p>Fixed-width integer values have their low bits emitted directly to the file.
+   For example, a 3-bit integer value encodes 1 as 001.  Fixed width integers

+zero.  Values larger than N-1 bits emit their bits in a series of N-1 bit
+chunks, where all but the last set the high bit.</p>
+
+<p>For example, the value 27 (0x1B) is encoded as 1011 0011 when emitted as a

+<p>
+Blocks in a bitstream denote nested regions of the stream, and are identified by
+a content-specific id number (for example, LLVM IR uses an ID of 12 to represent
+function bodies).  Nested blocks capture the hierachical structure of the data
+encoded in it, and various properties are associated with blocks as the file is
+parsed.  Block definitions allow the reader to efficiently skip blocks
+in constant time if the reader wants a summary of blocks, or if it wants to
+efficiently skip data they do not understand.  The LLVM IR reader uses this
+mechanism to skip function bodies, lazily reading them on demand.
+</p>
+
+<p>
+When reading and encoding the stream, several properties are maintained for the
+block.  In particular, each block maintains:
+</p>
+
+<ol>
+<li>A current abbrev id width.  This value starts at 2, and is set every time a
+    block record is entered.  The block entry specifies the abbrev id width for

+
+<li>A set of abbreviations.  Abbreviations may be defined within a block, or
+    they may be associated with all blocks of a particular ID.
+</li>
+</ol>
+
+<p>As sub blocks are entered, these properties are saved and the new sub-block

+Data records consist of a record code and a number of (up to) 64-bit integer
+values.  The interpretation of the code and values is application specific and
+there are multiple different ways to encode a record (with an unabbrev record
+or with an abbreviation).  In the LLVM IR format, for example, there is a record
+which encodes the target triple of a module.  The code is MODULE_CODE_TRIPLE,
+and the values of the record are the ascii codes for the characters in the

+
+<p>An UNABBREV_RECORD provides a default fallback encoding, which is both

+record, by emitting the code and operands as vbrs.</p>
+
+<p>For example, emitting an LLVM IR target triple as an unabbreviated record
+requires emitting the UNABBREV_RECORD abbrevid, a vbr6 for the
+MODULE_CODE_TRIPLE code, a vbr6 for the length of the string (which is equal to
+the number of operands), and a vbr6 for each character.  Since there are no
+letters with value less than 32, each letter would need to be emitted as at
+least a two-part VBR, which means that each letter would require at least 12
+bits.  This is not an efficient encoding, but it is fully general.</p>

+
+<p>An abbreviated record is a abbreviation id followed by a set of fields that
+are encoded according to the <a href="#abbreviations">abbreviation 
+definition</a>.  This allows records to be encoded significantly more densely
+than records encoded with the <a href="#UNABBREV_RECORD">UNABBREV_RECORD</a>

+<div class="doc_text">
+<p>
+Abbreviations are an important form of compression for bitstreams.  The idea is
+to specify a dense encoding for a class of records once, then use that encoding
+to emit many records.  It takes space to emit the encoding into the file, but
+the space is recouped (hopefully plus some) when the records that use it are
+emitted.
+</p>
+
+<p>
+Abbreviations can be determined dynamically per client, per file.  Since the
+abbreviations are stored in the bitstream itself, different streams of the same
+format can contain different sets of abbreviations if the specific stream does
+not need it.  As a concrete example, LLVM IR files usually emit an abbreviation
+for binary operators.  If a specific LLVM module contained no or few binary
+operators, the abbreviation does not need to be emitted.

+ ...]</tt></p>
+
+<p>An abbreviation definition consists of the DEFINE_ABBREV abbrevid followed
+by a VBR that specifies the number of abbrev operands, then the abbrev
+operands themselves.  Abbreviation operands come in three forms.  They all start
+with a single bit that indicates whether the abbrev operand is a literal operand
+(when the bit is 1) or an encoding operand (when the bit is 0).</p>
+
+<ol>
+<li>Literal operands - <tt>[1<sub>1</sub>, litvalue<sub>vbr8</sub>]</tt> -
+Literal operands specify that the value in the result
+is always a single specific value.  This specific value is emitted as a vbr8
+after the bit indicating that it is a literal operand.</li>
+<li>Encoding info without data - <tt>[0<sub>1</sub>, encoding<sub>3</sub>]</tt>
+ - Operand encodings that do not have extra data are just emitted as their code.
+</li>
+<li>Encoding info with data - <tt>[0<sub>1</sub>, encoding<sub>3</sub>, 
+value<sub>vbr5</sub>]</tt> - Operand encodings that do have extra data are
+emitted as their code, followed by the extra data.
+</li>
+</ol>
+
+<p>The possible operand encodings are:</p>
+
+<ul>
+<li>1 - Fixed - The field should be emitted as a <a 
+    href="#fixedwidth">fixed-width value</a>, whose width
+    is specified by the encoding operand.</li>
+<li>2 - VBR - The field should be emitted as a <a 
+    href="#variablewidth">variable-width value</a>, whose width
+    is specified by the encoding operand.</li>
+<li>3 - Array - This field is an array of values.  The element type of the array
+    is specified by the next encoding operand.</li>
+<li>4 - Char6 - This field should be emitted as a <a href="#char6">char6-encoded
+    value</a>.</li>
+</ul>
+
+<p>For example, target triples in LLVM modules are encoded as a record of the
+form <tt>[TRIPLE, 'a', 'b', 'c', 'd']</tt>.  Consider if the bitstream emitted
+the following abbrev entry:</p>
+
+<ul>
+<li><tt>[0, Fixed, 4]</tt></li>
+<li><tt>[0, Array]</tt></li>
+<li><tt>[0, Char6]</tt></li>
+</ul>
+
+<p>When emitting a record with this abbreviation, the above entry would be
+emitted as:</p>
+
+<p><tt>[4<sub>abbrevwidth</sub>, 2<sub>4</sub>, 4<sub>vbr6</sub>,
+   0<sub>6</sub>, 1<sub>6</sub>, 2<sub>6</sub>, 3<sub>6</sub>]</tt></p>
+
+<p>These values are:</p>
+
+<ol>
+<li>The first value, 4, is the abbreviation ID for this abbreviation.</li>
+<li>The second value, 2, is the code for TRIPLE in LLVM IR files.</li>
+<li>The third value, 4, is the length of the array.</li>
+<li>The rest of the values are the char6 encoded values for "abcd".</li>
+</ol>
+
+<p>With this abbreviation, the triple is emitted with only 37 bits (assuming a
+abbrev id width of 3).  Without the abbreviation, significantly more space would
+be required to emit the target triple.  Also, since the TRIPLE value is not
+emitted as a literal in the abbreviation, the abbreviation can also be used for
+any other string value.

+.SH "NAME"
+bugpoint \- automatic test case reduction tool
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"

+\&\fIprogram arguments\fR
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBbugpoint\fR narrows down the source of problems in \s-1LLVM\s0 tools and passes.  It
+can be used to debug three types of failures: optimizer crashes, miscompilations
+by optimizers, or bad native code generation (including problems in the static
+and \s-1JIT\s0 compilers).  It aims to reduce large test cases to small, useful ones.
+For more information on the design and inner workings of \fBbugpoint\fR, as well as
+advice for using bugpoint, see \fIllvm/docs/Bugpoint.html\fR in the \s-1LLVM\s0
+distribution.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-\-additional\-so\fR \fIlibrary\fR" 4
+.IX Item "--additional-so library"
+Load the dynamic shared object \fIlibrary\fR into the test program whenever it is
+run.  This is useful if you are debugging programs which depend on non-LLVM
+libraries (such as the X or curses libraries) to run.
+.IP "\fB\-\-args\fR \fIprogram args\fR" 4
+.IX Item "--args program args"
+Pass all arguments specified after \-args to the test program whenever it runs.
+Note that if any of the \fIprogram args\fR start with a '\-', you should use:
+.Sp
+.Vb 1
+\&    bugpoint [bugpoint args] --args -- [program args]
+.Ve
+.Sp
+The \*(L"\-\-\*(R" right after the \fB\-\-args\fR option tells \fBbugpoint\fR to consider any
+options starting with \f(CW\*(C`\-\*(C'\fR to be part of the \fB\-\-args\fR option, not as options to
+\&\fBbugpoint\fR itself.
+.IP "\fB\-\-tool\-args\fR \fItool args\fR" 4
+.IX Item "--tool-args tool args"
+Pass all arguments specified after \-\-tool\-args to the \s-1LLVM\s0 tool under test
+(\fBllc\fR, \fBlli\fR, etc.) whenever it runs.  You should use this option in the
+following way:
+.Sp
+.Vb 1
+\&    bugpoint [bugpoint args] --tool-args -- [tool args]
+.Ve
+.Sp
+The \*(L"\-\-\*(R" right after the \fB\-\-tool\-args\fR option tells \fBbugpoint\fR to consider any
+options starting with \f(CW\*(C`\-\*(C'\fR to be part of the \fB\-\-tool\-args\fR option, not as
+options to \fBbugpoint\fR itself. (See \fB\-\-args\fR, above.)
+.IP "\fB\-\-check\-exit\-code\fR=\fI{true,false}\fR" 4
+.IX Item "--check-exit-code={true,false}"
+Assume a non-zero exit code or core dump from the test program is a failure.
+Defaults to true.
+.IP "\fB\-\-disable\-{dce,simplifycfg}\fR" 4
+.IX Item "--disable-{dce,simplifycfg}"
+Do not run the specified passes to clean up and reduce the size of the test
+program. By default, \fBbugpoint\fR uses these passes internally when attempting to
+reduce test programs.  If you're trying to find a bug in one of these passes,
+\&\fBbugpoint\fR may crash.
+.IP "\fB\-find\-bugs\fR" 4
+.IX Item "-find-bugs"
+Continually randomize the specified passes and run them on the test program
+until a bug is found or the user kills \fBbugpoint\fR. 
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a summary of command line options.
+.IP "\fB\-\-input\fR \fIfilename\fR" 4
+.IX Item "--input filename"
+Open \fIfilename\fR and redirect the standard input of the test program, whenever
+it runs, to come from that file.
+.IP "\fB\-\-load\fR \fIplugin\fR" 4
+.IX Item "--load plugin"
+Load the dynamic object \fIplugin\fR into \fBbugpoint\fR itself.  This object should
+register new optimization passes.  Once loaded, the object will add new command
+line options to enable various optimizations.  To see the new complete list of
+optimizations, use the \fB\-\-help\fR and \fB\-\-load\fR options together; for example:
+.Sp
+.Vb 1
+\&    bugpoint --load myNewPass.so --help
+.Ve
+.IP "\fB\-\-output\fR \fIfilename\fR" 4
+.IX Item "--output filename"
+Whenever the test program produces output on its standard output stream, it
+should match the contents of \fIfilename\fR (the \*(L"reference output\*(R"). If you
+do not use this option, \fBbugpoint\fR will attempt to generate a reference output
+by compiling the program with the C backend and running it.
+.IP "\fB\-\-profile\-info\-file\fR \fIfilename\fR" 4
+.IX Item "--profile-info-file filename"
+Profile file loaded by \fB\-\-profile\-loader\fR.
+.IP "\fB\-\-run\-{int,jit,llc,cbe}\fR" 4
+.IX Item "--run-{int,jit,llc,cbe}"
+Whenever the test program is compiled, \fBbugpoint\fR should generate code for it
+using the specified code generator.  These options allow you to choose the
+interpreter, the \s-1JIT\s0 compiler, the static native code compiler, or the C
+backend, respectively.
+.IP "\fB\-\-enable\-valgrind\fR" 4
+.IX Item "--enable-valgrind"
+Use valgrind to find faults in the optimization phase. This will allow
+bugpoint to find otherwise asymptomatic problems caused by memory
+mis\-management.
+.SH "EXIT STATUS"
+.IX Header "EXIT STATUS"
+If \fBbugpoint\fR succeeds in finding a problem, it will exit with 0.  Otherwise,
+if an error occurs, it will exit with a non-zero value.

+llc \- LLVM static compiler
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+\&\fBllc\fR [\fIoptions\fR] [\fIfilename\fR]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBllc\fR command compiles \s-1LLVM\s0 bytecode into assembly language for a
+specified architecture.  The assembly language output can then be passed through
+a native assembler and linker to generate a native executable.
+.PP
+The choice of architecture for the output assembly code is automatically
+determined from the input bytecode file, unless the \fB\-march\fR option is used to
+override the default.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+If \fIfilename\fR is \- or omitted, \fBllc\fR reads \s-1LLVM\s0 bytecode from standard input.
+Otherwise, it will read \s-1LLVM\s0 bytecode from \fIfilename\fR.
+.PP
+If the \fB\-o\fR option is omitted, then \fBllc\fR will send its output to standard
+output if the input is from standard input.  If the \fB\-o\fR option specifies \-,
+then the output will also be sent to standard output.
+.PP
+If no \fB\-o\fR option is specified and an input file other than \- is specified,
+then \fBllc\fR creates the output filename by taking the input filename,
+removing any existing \fI.bc\fR extension, and adding a \fI.s\fR suffix.
+.PP
+Other \fBllc\fR options are as follows:
+.Sh "End-user Options"
+.IX Subsection "End-user Options"
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a summary of command line options.
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Overwrite output files. By default, \fBllc\fR will refuse to overwrite
+an output file which already exists.
+.IP "\fB\-mtriple\fR=\fItarget triple\fR" 4
+.IX Item "-mtriple=target triple"
+Override the target triple specified in the input bytecode file with the 
+specified string.
+.IP "\fB\-march\fR=\fIarch\fR" 4
+.IX Item "-march=arch"
+Specify the architecture for which to generate assembly, overriding the target
+encoded in the bytecode file.  See the output of \fBllc \-\-help\fR for a list of
+valid architectures.  By default this is inferred from the target triple or
+autodetected to the current architecture.
+.IP "\fB\-mcpu\fR=\fIcpuname\fR" 4
+.IX Item "-mcpu=cpuname"
+Specify a specific chip in the current architecture to generate code for.
+By default this is inferred from the target triple and autodetected to 
+the current architecture.  For a list of available CPUs, use:
+\&\fBllvm-as < /dev/null | llc \-march=xyz \-mcpu=help\fR
+.IP "\fB\-mattr\fR=\fIa1,+a2,\-a3,...\fR" 4
+.IX Item "-mattr=a1,+a2,-a3,..."
+Override or control specific attributes of the target, such as whether \s-1SIMD\s0
+operations are enabled or not.  The default set of attributes is set by the
+current \s-1CPU\s0.  For a list of available attributes, use:
+\&\fBllvm-as < /dev/null | llc \-march=xyz \-mattr=help\fR
+.IP "\fB\-\-disable\-fp\-elim\fR" 4
+.IX Item "--disable-fp-elim"
+Disable frame pointer elimination optimization.
+.IP "\fB\-\-disable\-excess\-fp\-precision\fR" 4
+.IX Item "--disable-excess-fp-precision"
+Disable optimizations that may produce excess precision for floating point.
+Note that this option can dramatically slow down code on some systems
+(e.g. X86).
+.IP "\fB\-\-enable\-unsafe\-fp\-math\fR" 4
+.IX Item "--enable-unsafe-fp-math"
+Enable optimizations that make unsafe assumptions about \s-1IEEE\s0 math (e.g. that
+addition is associative) or may not work for all input ranges.  These
+optimizations allow the code generator to make use of some instructions which
+would otherwise not be usable (such as fsin on X86).
+.IP "\fB\-\-enable\-correct\-eh\-support\fR" 4
+.IX Item "--enable-correct-eh-support"
+Instruct the \fBlowerinvoke\fR pass to insert code for correct exception handling
+support.  This is expensive and is by default omitted for efficiency.
+.IP "\fB\-\-stats\fR" 4
+.IX Item "--stats"
+Print statistics recorded by code-generation passes.
+.IP "\fB\-\-time\-passes\fR" 4
+.IX Item "--time-passes"
+Record the amount of time needed for each pass and print a report to standard
+error.
+.IP "\fB\-\-load\fR=\fIdso_path\fR" 4
+.IX Item "--load=dso_path"
+Dynamically load \fIdso_path\fR (a path to a dynamically shared object) that
+implements an \s-1LLVM\s0 target. This will permit the target name to be used with the
+\&\fB\-march\fR option so that code can be generated for that target.

+.IX Header "DESCRIPTION"
+\&\fBlli\fR directly executes programs in \s-1LLVM\s0 bytecode format.  It takes a program
+in \s-1LLVM\s0 bytecode format and executes it using a just-in-time compiler, if one is
+available for the current architecture, or an interpreter.  \fBlli\fR takes all of
+the same code generator options as llc, but they are only effective when
+\&\fBlli\fR is using the just-in-time compiler.
+.PP
+If \fIfilename\fR is not specified, then \fBlli\fR reads the \s-1LLVM\s0 bytecode for the
+program from standard input.

+.IX Title "LLVM-AR 1"
+.TH LLVM-AR 1 "2006-11-20" "CVS" "LLVM Command Guide"
+.SH "NAME"
+llvm\-ar \- LLVM archiver
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+\&\fBllvm-ar\fR [\-]{dmpqrtx}[Rabfikouz] [relpos] [count] <archive> [files...]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBllvm-ar\fR command is similar to the common Unix utility, \f(CW\*(C`ar\*(C'\fR. It 
+archives several files together into a single file. The intent for this is
+to produce archive libraries by \s-1LLVM\s0 bytecode that can be linked into an
+\&\s-1LLVM\s0 program. However, the archive can contain any kind of file. By default,
+\&\fBllvm-ar\fR generates a symbol table that makes linking faster because
+only the symbol table needs to be consulted, not each individual file member
+of the archive. 
+.PP
+The \fBllvm-ar\fR command can be used to \fIread\fR both \s-1SVR4\s0 and \s-1BSD\s0 style archive
+files. However, it cannot be used to write them.  While the \fBllvm-ar\fR command 
+produces files that are \fIalmost\fR identical to the format used by other \f(CW\*(C`ar\*(C'\fR 
+implementations, it has two significant departures in order to make the 
+archive appropriate for \s-1LLVM\s0. The first departure is that \fBllvm-ar\fR only
+uses \s-1BSD4\s0.4 style long path names (stored immediately after the header) and
+never contains a string table for long names. The second departure is that the
+symbol table is formated for efficient construction of an in-memory data
+structure that permits rapid (red\-black tree) lookups. Consequently, archives 
+produced with \fBllvm-ar\fR usually won't be readable or editable with any
+\&\f(CW\*(C`ar\*(C'\fR implementation or useful for linking.  Using the \f(CW\*(C`f\*(C'\fR modifier to flatten
+file names will make the archive readable by other \f(CW\*(C`ar\*(C'\fR implementations
+but not for linking because the symbol table format for \s-1LLVM\s0 is unique. If an
+\&\s-1SVR4\s0 or \s-1BSD\s0 style archive is used with the \f(CW\*(C`r\*(C'\fR (replace) or \f(CW\*(C`q\*(C'\fR (quick
+update) operations, the archive will be reconstructed in \s-1LLVM\s0 format. This 
+means that the string table will be dropped (in deference to \s-1BSD\s0 4.4 long names)
+and an \s-1LLVM\s0 symbol table will be added (by default). The system symbol table
+will be retained.
+.PP
+Here's where \fBllvm-ar\fR departs from previous \f(CW\*(C`ar\*(C'\fR implementations:
+.IP "\fISymbol Table\fR" 4
+.IX Item "Symbol Table"
+Since \fBllvm-ar\fR is intended to archive bytecode files, the symbol table
+won't make much sense to anything but \s-1LLVM\s0. Consequently, the symbol table's
+format has been simplified. It consists simply of a sequence of pairs
+of a file member index number as an \s-1LSB\s0 4byte integer and a null-terminated 
+string.
+.IP "\fILong Paths\fR" 4
+.IX Item "Long Paths"
+Some \f(CW\*(C`ar\*(C'\fR implementations (\s-1SVR4\s0) use a separate file member to record long
+path names (> 15 characters). \fBllvm-ar\fR takes the \s-1BSD\s0 4.4 and Mac \s-1OS\s0 X 
+approach which is to simply store the full path name immediately preceding
+the data for the file. The path name is null terminated and may contain the
+slash (/) character. 
+.IP "\fICompression\fR" 4
+.IX Item "Compression"
+\&\fBllvm-ar\fR can compress the members of an archive to save space. The 
+compression used depends on what's available on the platform and what choices
+the \s-1LLVM\s0 Compressor utility makes. It generally favors bzip2 but will select
+between \*(L"no compression\*(R" or bzip2 depending on what makes sense for the
+file's content.
+.IP "\fIDirectory Recursion\fR" 4
+.IX Item "Directory Recursion"
+Most \f(CW\*(C`ar\*(C'\fR implementations do not recurse through directories but simply
+ignore directories if they are presented to the program in the \fIfiles\fR 
+option. \fBllvm-ar\fR, however, can recurse through directory structures and
+add all the files under a directory, if requested.
+.IP "\fI\s-1TOC\s0 Verbose Output\fR" 4
+.IX Item "TOC Verbose Output"
+When \fBllvm-ar\fR prints out the verbose table of contents (\f(CW\*(C`tv\*(C'\fR option), it
+precedes the usual output with a character indicating the basic kind of 
+content in the file. A blank means the file is a regular file. A 'Z' means
+the file is compressed. A 'B' means the file is an \s-1LLVM\s0 bytecode file. An
+\&'S' means the file is the symbol table.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+The options to \fBllvm-ar\fR are compatible with other \f(CW\*(C`ar\*(C'\fR implementations.
+However, there are a few modifiers (\fIzR\fR) that are not found in other
+\&\f(CW\*(C`ar\*(C'\fRs. The options to \fBllvm-ar\fR specify a single basic operation to 
+perform on the archive, a variety of modifiers for that operation, the
+name of the archive file, and an optional list of file names. These options
+are used to determine how \fBllvm-ar\fR should process the archive file.
+.PP
+The Operations and Modifiers are explained in the sections below. The minimal
+set of options is at least one operator and the name of the archive. Typically
+archive files end with a \f(CW\*(C`.a\*(C'\fR suffix, but this is not required. Following
+the \fIarchive-name\fR comes a list of \fIfiles\fR that indicate the specific members
+of the archive to operate on. If the \fIfiles\fR option is not specified, it
+generally means either \*(L"none\*(R" or \*(L"all\*(R" members, depending on the operation.
+.Sh "Operations"
+.IX Subsection "Operations"
+.IP "d" 4
+.IX Item "d"
+Delete files from the archive. No modifiers are applicable to this operation.
+The \fIfiles\fR options specify which members should be removed from the
+archive. It is not an error if a specified file does not appear in the archive.
+If no \fIfiles\fR are specified, the archive is not modified.
+.IP "m[abi]" 4
+.IX Item "m[abi]"
+Move files from one location in the archive to another. The \fIa\fR, \fIb\fR, and 
+\&\fIi\fR modifiers apply to this operation. The \fIfiles\fR will all be moved
+to the location given by the modifiers. If no modifiers are used, the files
+will be moved to the end of the archive. If no \fIfiles\fR are specified, the
+archive is not modified.
+.IP "p[k]" 4
+.IX Item "p[k]"
+Print files to the standard output. The \fIk\fR modifier applies to this
+operation. This operation simply prints the \fIfiles\fR indicated to the
+standard output. If no \fIfiles\fR are specified, the entire archive is printed.
+Printing bytecode files is ill-advised as they might confuse your terminal
+settings. The \fIp\fR operation never modifies the archive.
+.IP "q[Rfz]" 4
+.IX Item "q[Rfz]"
+Quickly append files to the end of the archive. The \fIR\fR, \fIf\fR, and \fIz\fR
+modifiers apply to this operation.  This operation quickly adds the 
+\&\fIfiles\fR to the archive without checking for duplicates that should be 
+removed first. If no \fIfiles\fR are specified, the archive is not modified. 
+Because of the way that \fBllvm-ar\fR constructs the archive file, its dubious 
+whether the \fIq\fR operation is any faster than the \fIr\fR operation.
+.IP "r[Rabfuz]" 4
+.IX Item "r[Rabfuz]"
+Replace or insert file members. The \fIR\fR, \fIa\fR, \fIb\fR, \fIf\fR, \fIu\fR, and \fIz\fR
+modifiers apply to this operation. This operation will replace existing
+\&\fIfiles\fR or insert them at the end of the archive if they do not exist. If no
+\&\fIfiles\fR are specified, the archive is not modified.
+.IP "t[v]" 4
+.IX Item "t[v]"
+Print the table of contents. Without any modifiers, this operation just prints
+the names of the members to the standard output. With the \fIv\fR modifier,
+\&\fBllvm-ar\fR also prints out the file type (B=bytecode, Z=compressed, S=symbol
+table, blank=regular file), the permission mode, the owner and group, the
+size, and the date. If any \fIfiles\fR are specified, the listing is only for
+those files. If no \fIfiles\fR are specified, the table of contents for the
+whole archive is printed.
+.IP "x[oP]" 4
+.IX Item "x[oP]"
+Extract archive members back to files. The \fIo\fR modifier applies to this
+operation. This operation retrieves the indicated \fIfiles\fR from the archive 
+and writes them back to the operating system's file system. If no 
+\&\fIfiles\fR are specified, the entire archive is extract. 
+.Sh "Modifiers (operation specific)"
+.IX Subsection "Modifiers (operation specific)"
+The modifiers below are specific to certain operations. See the Operations
+section (above) to determine which modifiers are applicable to which operations.
+.IP "[a]" 4
+.IX Item "[a]"
+When inserting or moving member files, this option specifies the destination of
+the new files as being \f(CW\*(C`a\*(C'\fRfter the \fIrelpos\fR member. If \fIrelpos\fR is not found,
+the files are placed at the end of the archive.
+.IP "[b]" 4
+.IX Item "[b]"
+When inserting or moving member files, this option specifies the destination of
+the new files as being \f(CW\*(C`b\*(C'\fRefore the \fIrelpos\fR member. If \fIrelpos\fR is not 
+found, the files are placed at the end of the archive. This modifier is 
+identical to the the \fIi\fR modifier.
+.IP "[f]" 4
+.IX Item "[f]"
+Normally, \fBllvm-ar\fR stores the full path name to a file as presented to it on
+the command line. With this option, truncated (15 characters max) names are
+used. This ensures name compatibility with older versions of \f(CW\*(C`ar\*(C'\fR but may also
+thwart correct extraction of the files (duplicates may overwrite). If used with
+the \fIR\fR option, the directory recursion will be performed but the file names
+will all be \f(CW\*(C`f\*(C'\fRlattened to simple file names.
+.IP "[i]" 4
+.IX Item "[i]"
+A synonym for the \fIb\fR option.
+.IP "[k]" 4
+.IX Item "[k]"
+Normally, \fBllvm-ar\fR will not print the contents of bytecode files when the 
+\&\fIp\fR operation is used. This modifier defeats the default and allows the 
+bytecode members to be printed.
+.IP "[N]" 4
+.IX Item "[N]"
+This option is ignored by \fBllvm-ar\fR but provided for compatibility.
+.IP "[o]" 4
+.IX Item "[o]"
+When extracting files, this option will cause \fBllvm-ar\fR to preserve the
+original modification times of the files it writes. 
+.IP "[P]" 4
+.IX Item "[P]"
+use full path names when matching
+.IP "[R]" 4
+.IX Item "[R]"
+This modifier instructions the \fIr\fR option to recursively process directories.
+Without \fIR\fR, directories are ignored and only those \fIfiles\fR that refer to
+files will be added to the archive. When \fIR\fR is used, any directories specified
+with \fIfiles\fR will be scanned (recursively) to find files to be added to the
+archive. Any file whose name begins with a dot will not be added.
+.IP "[u]" 4
+.IX Item "[u]"
+When replacing existing files in the archive, only replace those files that have
+a time stamp than the time stamp of the member in the archive.
+.IP "[z]" 4
+.IX Item "[z]"
+When inserting or replacing any file in the archive, compress the file first.
+This
+modifier is safe to use when (previously) compressed bytecode files are added to
+the archive; the compressed bytecode files will not be doubly compressed.
+.Sh "Modifiers (generic)"
+.IX Subsection "Modifiers (generic)"
+The modifiers below may be applied to any operation.
+.IP "[c]" 4
+.IX Item "[c]"
+For all operations, \fBllvm-ar\fR will always create the archive if it doesn't 
+exist. Normally, \fBllvm-ar\fR will print a warning message indicating that the
+archive is being created. Using this modifier turns off that warning.
+.IP "[s]" 4
+.IX Item "[s]"
+This modifier requests that an archive index (or symbol table) be added to the
+archive. This is the default mode of operation. The symbol table will contain
+all the externally visible functions and global variables defined by all the
+bytecode files in the archive. Using this modifier is more efficient that using
+llvm-ranlib which also creates the symbol table.
+.IP "[S]" 4
+.IX Item "[S]"
+This modifier is the opposite of the \fIs\fR modifier. It instructs \fBllvm-ar\fR to
+not build the symbol table. If both \fIs\fR and \fIS\fR are used, the last modifier to
+occur in the options will prevail. 
+.IP "[v]" 4
+.IX Item "[v]"
+This modifier instructs \fBllvm-ar\fR to be verbose about what it is doing. Each
+editing operation taken against the archive will produce a line of output saying
+what is being done.
+.SH "STANDARDS"
+.IX Header "STANDARDS"
+The \fBllvm-ar\fR utility is intended to provide a superset of the \s-1IEEE\s0 Std 1003.2
+(\s-1POSIX\s0.2) functionality for \f(CW\*(C`ar\*(C'\fR. \fBllvm-ar\fR can read both \s-1SVR4\s0 and \s-1BSD4\s0.4 (or
+Mac \s-1OS\s0 X) archives. If the \f(CW\*(C`f\*(C'\fR modifier is given to the \f(CW\*(C`x\*(C'\fR or \f(CW\*(C`r\*(C'\fR operations
+then \fBllvm-ar\fR will write \s-1SVR4\s0 compatible archives. Without this modifier, 
+\&\fBllvm-ar\fR will write \s-1BSD4\s0.4 compatible archives that have long names
+immediately after the header and indicated using the \*(L"#1/ddd\*(R" notation for the
+name in the header.
+.SH "FILE FORMAT"
+.IX Header "FILE FORMAT"
+The file format for \s-1LLVM\s0 Archive files is similar to that of \s-1BSD\s0 4.4 or Mac \s-1OSX\s0
+archive files. In fact, except for the symbol table, the \f(CW\*(C`ar\*(C'\fR commands on those
+operating systems should be able to read \s-1LLVM\s0 archive files. The details of the
+file format follow.

+Each archive begins with the archive magic number which is the eight printable
+characters \*(L"!<arch>\en\*(R" where \en represents the newline character (0x0A). 
+Following the magic number, the file is composed of even length members that 
+begin with an archive header and end with a \en padding character if necessary 
+(to make the length even). Each file member is composed of a header (defined 
+below), an optional newline-terminated \*(L"long file name\*(R" and the contents of 
+the file. 
+.PP
+The fields of the header are described in the items below. All fields of the
+header contain only \s-1ASCII\s0 characters, are left justified and are right padded 
+with space characters.
+.IP "name \- char[16]" 4
+.IX Item "name - char[16]"
+This field of the header provides the name of the archive member. If the name is
+longer than 15 characters or contains a slash (/) character, then this field
+contains \f(CW\*(C`#1/nnn\*(C'\fR where \f(CW\*(C`nnn\*(C'\fR provides the length of the name and the \f(CW\*(C`#1/\*(C'\fR
+is literal.  In this case, the actual name of the file is provided in the \f(CW\*(C`nnn\*(C'\fR
+bytes immediately following the header. If the name is 15 characters or less, it
+is contained directly in this field and terminated with a slash (/) character.
+.IP "date \- char[12]" 4
+.IX Item "date - char[12]"
+This field provides the date of modification of the file in the form of a
+decimal encoded number that provides the number of seconds since the epoch 
+(since 00:00:00 Jan 1, 1970) per Posix specifications.
+.IP "uid \- char[6]" 4
+.IX Item "uid - char[6]"
+This field provides the user id of the file encoded as a decimal \s-1ASCII\s0 string.
+This field might not make much sense on non-Unix systems. On Unix, it is the
+same value as the st_uid field of the stat structure returned by the \fIstat\fR\|(2)
+operating system call.
+.IP "gid \- char[6]" 4
+.IX Item "gid - char[6]"
+This field provides the group id of the file encoded as a decimal \s-1ASCII\s0 string.
+This field might not make much sense on non-Unix systems. On Unix, it is the
+same value as the st_gid field of the stat structure returned by the \fIstat\fR\|(2)
+operating system call.
+.IP "mode \- char[8]" 4
+.IX Item "mode - char[8]"
+This field provides the access mode of the file encoded as an octal \s-1ASCII\s0 
+string. This field might not make much sense on non-Unix systems. On Unix, it 
+is the same value as the st_mode field of the stat structure returned by the 
+\&\fIstat\fR\|(2) operating system call.
+.IP "size \- char[10]" 4
+.IX Item "size - char[10]"
+This field provides the size of the file, in bytes, encoded as a decimal \s-1ASCII\s0
+string. If the size field is negative (starts with a minus sign, 0x02D), then
+the archive member is stored in compressed form. The first byte of the archive
+member's data indicates the compression type used. A value of 0 (0x30) indicates
+that no compression was used. A value of 2 (0x32) indicates that bzip2
+compression was used.
+.IP "fmag \- char[2]" 4
+.IX Item "fmag - char[2]"
+This field is the archive file member magic number. Its content is always the
+two characters back tick (0x60) and newline (0x0A). This provides some measure 
+utility in identifying archive files that have been corrupted.
+.PP
+The \s-1LLVM\s0 symbol table has the special name \*(L"#_LLVM_SYM_TAB_#\*(R". It is presumed
+that no regular archive member file will want this name. The \s-1LLVM\s0 symbol table 
+is simply composed of a sequence of triplets: byte offset, length of symbol, 
+and the symbol itself. Symbols are not null or newline terminated. Here are 
+the details on each of these items:
+.IP "offset \- vbr encoded 32\-bit integer" 4
+.IX Item "offset - vbr encoded 32-bit integer"
+The offset item provides the offset into the archive file where the bytecode
+member is stored that is associated with the symbol. The offset value is 0
+based at the start of the first \*(L"normal\*(R" file member. To derive the actual
+file offset of the member, you must add the number of bytes occupied by the file
+signature (8 bytes) and the symbol tables. The value of this item is encoded
+using variable bit rate encoding to reduce the size of the symbol table.
+Variable bit rate encoding uses the high bit (0x80) of each byte to indicate 
+if there are more bytes to follow. The remaining 7 bits in each byte carry bits
+from the value. The final byte does not have the high bit set.
+.IP "length \- vbr encoded 32\-bit integer" 4
+.IX Item "length - vbr encoded 32-bit integer"
+The length item provides the length of the symbol that follows. Like this
+\&\fIoffset\fR item, the length is variable bit rate encoded.
+.IP "symbol \- character array" 4
+.IX Item "symbol - character array"
+The symbol item provides the text of the symbol that is associated with the
+\&\fIoffset\fR. The symbol is not terminated by any character. Its length is provided
+by the \fIlength\fR field. Note that is allowed (but unwise) to use non-printing
+characters (even 0x00) in the symbol. This allows for multiple encodings of 
+symbol names.
+.SH "EXIT STATUS"
+.IX Header "EXIT STATUS"
+If \fBllvm-ar\fR succeeds, it will exit with 0.  A usage error, results
+in an exit code of 1. A hard (file system typically) error results in an

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBllvm-bcanalyzer\fR command is a small utility for analyzing bytecode files.
+The tool reads a bytecode file (such as generated with the \fBllvm-as\fR tool) and
+produces a statistical report on the contents of the byteocde file.  The tool
+can also dump a low level but human readable version of the bytecode file. 
+This tool is probably not of much interest or utility except for those working 
+directly with the bytecode file format. Most \s-1LLVM\s0 users can just ignore
+this tool.
+.PP
+If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-bcanalyzer\fR reads its input 
+from standard input. This is useful for combining the tool into a pipeline.
+Output is written to the standard output.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-nodetails\fR" 4
+.IX Item "-nodetails"
+Causes \fBllvm-bcanalyzer\fR to abbreviate its output by writing out only a module 
+level summary. The details for individual functions are not displayed.
+.IP "\fB\-dump\fR" 4
+.IX Item "-dump"
+Causes \fBllvm-bcanalyzer\fR to dump the bytecode in a human readable format. This 
+format is significantly different from \s-1LLVM\s0 assembly and provides details about 
+the encoding of the bytecode file.
+.IP "\fB\-verify\fR" 4
+.IX Item "-verify"
+Causes \fBllvm-bcanalyzer\fR to verify the module produced by reading the 
+bytecode. This ensures that the statistics generated are based on a consistent
+module.

+If filename is omitted or specified as \f(CW\*(C`\-\*(C'\fR, \fBllvm-dis\fR reads its
+input from standard input.
+.PP
+If the input is being read from standard input, then \fBllvm-dis\fR
+will send its output to standard output by default.  Otherwise, the
+output will be written to a file named after the input file, with
+a \f(CW\*(C`.ll\*(C'\fR suffix added (any existing \f(CW\*(C`.bc\*(C'\fR suffix will first be

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBllvm-ld\fR tool takes a set of \s-1LLVM\s0 bytecode files and links them
+together into a single \s-1LLVM\s0 bytecode file.  The output bytecode file can be
+another bytecode file or an executable bytecode program.  Using additional
+options, \fBllvm-ld\fR is able to produce native code executables.
+.PP
+The \fBllvm-ld\fR tool is the main linker for \s-1LLVM\s0. It is used to link together
+the output of \s-1LLVM\s0 front-end compilers and run \*(L"link time\*(R" optimizations (mostly
+the inter-procedural kind).
+.PP
+The \fBllvm-ld\fR tools attemps to mimic the interface provided by the default
+system linker so that it can act as a \fIdrop-in\fR replacement.
+.Sh "Search Order"
+.IX Subsection "Search Order"
+When looking for objects specified on the command line, \fBllvm-ld\fR will search 
+for the object first in the current directory and then in the directory 
+specified by the \fB\s-1LLVM_LIB_SEARCH_PATH\s0\fR environment variable.  If it cannot 
+find the object, it fails.
+.PP
+When looking for a library specified with the \fB\-l\fR option, \fBllvm-ld\fR first
+attempts to load a file with that name from the current directory.  If that
+fails, it looks for lib\fIlibrary\fR.bc, lib\fIlibrary\fR.a, or lib\fIlibrary\fR.\fIshared
+library extension\fR, in that order, in each directory added to the library search
+path with the \fB\-L\fR option.  These directories are searched in the order they
+are specified.  If the library cannot be located, then \fBllvm-ld\fR looks in the
+directory specified by the \fB\s-1LLVM_LIB_SEARCH_PATH\s0\fR environment variable.  If it
+does not find a library there, it fails.
+.PP
+The \fIshared library extension\fR may be \fI.so\fR, \fI.dyld\fR, \fI.dll\fR, or something
+different, depending upon the system.
+.PP
+The \fB\-L\fR option is global.  It does not matter where it is specified in the
+list of command line arguments; the directory is simply added to the search path
+and is applied to all libraries, preceding or succeeding, in the command line.
+.Sh "Link order"
+.IX Subsection "Link order"
+All object and bytecode files are linked first in the order they were 
+specified on the command line.  All library files are linked next.  
+Some libraries may not be linked into the object program; see below.
+.Sh "Library Linkage"
+.IX Subsection "Library Linkage"
+Object files and static bytecode objects are always linked into the output
+file.  Library archives (.a files) load only the objects within the archive
+that define symbols needed by the output file.  Hence, libraries should be
+listed after the object files and libraries which need them; otherwise, the
+library may not be linked in, and the dependent library will not have its
+undefined symbols defined.
+.Sh "Native code generation"
+.IX Subsection "Native code generation"
+The \fBllvm-ld\fR program has limited support for native code generation, when
+using the \fB\-native\fR or \fB\-native\-cbe\fR options. Native code generation is
+perfomed by converting the linked bytecode into native assembly (.s) or C code
+and running the system compiler (typically gcc) on the result.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.Sh "General Options"
+.IX Subsection "General Options"
+.IP "\fB\-help\fR" 4
+.IX Item "-help"
+Print a summary of command line options.
+.IP "\fB\-v\fR" 4
+.IX Item "-v"
+Specifies verbose mode. In this mode the linker will print additional
+information about the actions it takes, programs it executes, etc. 
+.IP "\fB\-stats\fR" 4
+.IX Item "-stats"
+Print statistics.
+.IP "\fB\-time\-passes\fR" 4
+.IX Item "-time-passes"
+Record the amount of time needed for each pass and print it to standard
+error.
+.Sh "Input/Output Options"
+.IX Subsection "Input/Output Options"
+.IP "\fB\-o\fR \fIfilename\fR" 4
+.IX Item "-o filename"
+This overrides the default output file and specifies the name of the file that
+should be generated by the linker. By default, \fBllvm-ld\fR generates a file named
+\&\fIa.out\fR for compatibility with \fBld\fR. The output will be written to
+\&\fIfilename\fR.
+.IP "\fB\-l\fR\fIname\fR" 4
+.IX Item "-lname"
+This option specifies the \fIname\fR of a library to search when resolving symbols
+for the program. Only the base name should be specified as \fIname\fR, without a
+\&\fIlib\fR prefix or any suffix. 
+.IP "\fB\-L\fR\fIPath\fR" 4
+.IX Item "-LPath"
+This option tells \fBllvm-ld\fR to look in \fIPath\fR to find any library subsequently
+specified with the \fB\-l\fR option. The paths will be searched in the order in
+which they are specified on the command line. If the library is still not found,
+a small set of system specific directories will also be searched. Note that
+libraries specified with the \fB\-l\fR option that occur \fIbefore\fR any \fB\-L\fR options
+will not search the paths given by the \fB\-L\fR options following it.
+.IP "\fB\-link\-as\-library\fR" 4
+.IX Item "-link-as-library"
+Link the bytecode files together as a library, not an executable. In this mode,
+undefined symbols will be permitted.
+.IP "\fB\-r\fR" 4
+.IX Item "-r"
+An alias for \-link\-as\-library.
+.ie n .IP "\fB\-march=\fR""target""" 4
+.el .IP "\fB\-march=\fR\f(CWtarget\fR" 4
+.IX Item "-march=target"
+Specifies the kind of machine for which code or assembly should be generated.
+.IP "\fB\-native\fR" 4
+.IX Item "-native"
+Generate a native machine code executable.
+.Sp
+When generating native executables, \fBllvm-ld\fR first checks for a bytecode
+version of the library and links it in, if necessary.  If the library is
+missing, \fBllvm-ld\fR skips it.  Then, \fBllvm-ld\fR links in the same
+libraries as native code.
+.Sp
+In this way, \fBllvm-ld\fR should be able to link in optimized bytecode
+subsets of common libraries and then link in any part of the library that
+hasn't been converted to bytecode.
+.IP "\fB\-native\-cbe\fR" 4
+.IX Item "-native-cbe"
+Generate a native machine code executable with the \s-1LLVM\s0 C backend.
+.Sp
+This option is identical to the \fB\-native\fR option, but uses the
+C backend to generate code for the program instead of an \s-1LLVM\s0 native
+code generator.
+.Sh "Optimization Options"
+.IX Subsection "Optimization Options"
+.IP "\fB\-O0\fR" 4
+.IX Item "-O0"
+An alias for the \-O1 option.
+.IP "\fB\-O1\fR" 4
+.IX Item "-O1"
+Optimize for linking speed, not execution speed. The optimizer will attempt to
+reduce the size of the linked program to reduce I/O but will not otherwise
+perform any link-time optimizations.
+.IP "\fB\-O2\fR" 4
+.IX Item "-O2"
+Perform only the minimal or required set of scalar optimizations.
+.IP "\fB\-03\fR" 4
+.IX Item "-03"
+An alias for the \-O2 option.
+.IP "\fB\-04\fR" 4
+.IX Item "-04"
+Perform the standard link time inter-procedural optimizations. This will 
+attempt to optimize the program taking the entire program into consideration.
+.IP "\fB\-O5\fR" 4
+.IX Item "-O5"
+Perform aggressive link time optimizations. This is the same as \-O4 but works
+more aggressively to optimize the program.
+.IP "\fB\-disable\-inlining\fR" 4
+.IX Item "-disable-inlining"
+Do not run the inlining pass. Functions will not be inlined into other
+functions.
+.IP "\fB\-disable\-opt\fR" 4
+.IX Item "-disable-opt"
+Completely disable optimization. The various \fB\-On\fR options will be ignored and
+no link time optimization passes will be run.
+.IP "\fB\-disable\-internalize\fR" 4
+.IX Item "-disable-internalize"
+Do not mark all symbols as internal.
+.IP "\fB\-verify\-each\fR" 4
+.IX Item "-verify-each"
+Run the verification pass after each of the passes to verify intermediate
+results.
+.IP "\fB\-strip\-all\fR" 4
+.IX Item "-strip-all"
+Strip all debug and symbol information from the executable to make it smaller.
+.IP "\fB\-strip\-debug\fR" 4
+.IX Item "-strip-debug"
+Strip all debug information from the executable to make it smaller.
+.IP "\fB\-s\fR" 4
+.IX Item "-s"
+An alias for \fB\-strip\-all\fR.
+.IP "\fB\-S\fR" 4
+.IX Item "-S"
+An alias for \fB\-strip\-debug\fR.
+.IP "\fB\-export\-dynamic\fR" 4
+.IX Item "-export-dynamic"
+An alias for \fB\-disable\-internalize\fR
+.IP "\fB\-load\fR \fImodule\fR" 4
+.IX Item "-load module"
+Load an optimization module, \fImodule\fR, which is expected to be a dynamic
+library that provides the function name \f(CW\*(C`RunOptimizations\*(C'\fR. This function will
+be passed the PassManager, and the optimization level (values 0\-5 based on the
+\&\fB\-On\fR option). This function may add passes to the PassManager that should be
+run. This feature allows the optimization passes of \fBllvm-ld\fR to be extended.
+.IP "\fB\-post\-link\-opt\fR\fIPath\fR" 4
+.IX Item "-post-link-optPath"
+Run post-link optimization program. After linking is completed a bytecode file
+will be generated. It will be passed to the program specified by \fIPath\fR as the
+first argument. The second argument to the program will be the name of a
+temporary file into which the program should place its optimized output. For
+example, the \*(L"no\-op optimization\*(R" would be a simple shell script:

+Each such output record consists of an (optional) 8\-digit hexadecimal address,
+followed by a type code character, followed by a name, for each symbol. One
+record is printed per line; fields are separated by spaces. When the address is
+omitted, it is replaced by 8 spaces.
+.PP
+Type code characters currently supported, and their meanings, are as follows:
+.IP "U" 4
+.IX Item "U"
+Named object is referenced but undefined in this bytecode file
+.IP "C" 4
+.IX Item "C"
+Common (multiple defs link together into one def)
+.IP "W" 4
+.IX Item "W"
+Weak reference (multiple defs link together into zero or one defs)
+.IP "t" 4
+.IX Item "t"
+Local function (text) object
+.IP "T" 4
+.IX Item "T"
+Global function (text) object
+.IP "d" 4
+.IX Item "d"
+Local data object
+.IP "D" 4
+.IX Item "D"
+Global data object
+.IP "?" 4
+Something unrecognizable
+.PP
+Because \s-1LLVM\s0 bytecode files typically contain objects that are not considered to
+have addresses until they are linked into an executable image or dynamically
+compiled \*(L"just\-in\-time\*(R", \fBllvm-nm\fR does not print an address for any symbol,
+even symbols which are defined in the bytecode file.
+.SH "OPTIONS"

+.IX Item "-B    (default)"
+Use \s-1BSD\s0 output format. Alias for \fB\-\-format=bsd\fR.
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a summary of command-line options and their meanings.
+.IP "\fB\-\-defined\-only\fR" 4
+.IX Item "--defined-only"
+Print only symbols defined in this bytecode file (as opposed to
+symbols which may be referenced by objects in this file, but not
+defined in this file.)
+.IP "\fB\-\-extern\-only\fR, \fB\-g\fR" 4
+.IX Item "--extern-only, -g"
+Print only symbols whose definitions are external; that is, accessible
+from other bytecode files.
+.IP "\fB\-\-undefined\-only\fR, \fB\-u\fR" 4
+.IX Item "--undefined-only, -u"
+Print only symbols referenced but not defined in this bytecode file.

+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBllvm-prof\fR tool reads in an \fIllvmprof.out\fR file (which can
+optionally use a specific file with the third program argument), a bytecode file
+for the program, and produces a human readable report, suitable for determining
+where the program hotspots are.
+.PP
+This program is often used in conjunction with the \fIutils/profile.pl\fR
+script.  This script automatically instruments a program, runs it with the \s-1JIT\s0,
+then runs \fBllvm-prof\fR to format a report.  To get more information about
+\&\fIutils/profile.pl\fR, execute it with the \fB\-\-help\fR option.

+In addition to the normal report printed, print out the code for the
+program, annotated with execution frequency information. This can be
+particularly useful when trying to visualize how frequently basic blocks
+are executed.  This is most useful with basic block profiling
+information or better.
+.IP "\fB\-\-print\-all\-code\fR" 4

+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+\&\fBllvm2cpp\fR [\fIoptions\fR] [\fIfilename\fR]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBllvm2cpp\fR translates from \s-1LLVM\s0 bytecode (.bc files) to a 
+corresponding \*(C+ source file that will make calls against the \s-1LLVM\s0 \*(C+ \s-1API\s0 to
+build the same module as the input. By default, the \*(C+ output is a complete
+program that builds the module, verifies it and then emits the module as
+\&\s-1LLVM\s0 assembly. This technique assists with testing because the input to
+\&\fBllvm2cpp\fR and the output of the generated \*(C+ program should be identical.
+.PP
+If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm2cpp\fR reads its input from
+standard input.
+.PP
+If an output file is not specified with the \fB\-o\fR option, then
+\&\fBllvm2cpp\fR sends its output to a file or standard output by following
+these rules:
+.IP "\(bu" 4
+If the input is standard input, then the output is standard output.
+.IP "\(bu" 4
+If the input is a file that ends with \f(CW\*(C`.bc\*(C'\fR, then the output file is of
+the same name, except that the suffix is changed to \f(CW\*(C`.cpp\*(C'\fR.
+.IP "\(bu" 4
+If the input is a file that does not end with the \f(CW\*(C`.bc\*(C'\fR suffix, then the
+output file has the same name as the input file, except that the \f(CW\*(C`.cpp\*(C'\fR
+suffix is appended.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Force overwrite.  Normally, \fBllvm2cpp\fR will refuse to overwrite an
+output file that already exists.  With this option, \fBllvm2cpp\fR
+will overwrite the output file and replace it with new \*(C+ source code.
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a summary of command line options.
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Normally, \fBllvm2cpp\fR will not overwrite an existing output file. With this
+option, that default behavior is changed and the program will overwrite existing
+output files.
+.IP "\fB\-o\fR \fIfilename\fR" 4
+.IX Item "-o filename"
+Specify the output file name.  If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm2cpp\fR
+sends its output to standard output.
+.IP "\fB\-funcname\fR \fIfunctionName\fR" 4
+.IX Item "-funcname functionName"
+Specify the name of the function to be generated. The generated code contains a
+single function that produces the input module. By default its name is
+\&\fImakeLLVMModule\fR. The \fB\-funcname\fR option overrides this default and allows
+you to control the name of the generated function. This is handy in conjunction
+with the \fB\-fragment\fR option when you only want \fBllvm2cpp\fR to generate a
+single function that produces the module. With both options, such generated code
+could be \fI#included\fR into another program.
+.IP "\fB\-for\fR" 4
+.IX Item "-for"
+Specify the name of the thing for which \*(C+ code should be generated. By default
+the entire input module is re\-generated. However, use of the various \fB\-gen\-*\fR
+options can restrict what is produced. This option indicates what that
+restriction is.
+.IP "\fB\-gen\-program\fR" 4
+.IX Item "-gen-program"
+Specify that the output should be a complete program. Such program will recreate
+\&\fBllvm2cpp\fR's input as an \s-1LLVM\s0 module, verify that module, and then write out
+the module in \s-1LLVM\s0 assembly format. This is useful for doing identity tests
+where the output of the generated program is identical to the input to
+\&\fBllvm2cpp\fR. The \s-1LLVM\s0 DejaGnu test suite can make use of this fact. This is the
+default form of generated output.
+.Sp
+If the \fB\-for\fR option is given with this option, it specifies the module
+identifier to use for the module created.
+.IP "\fB\-gen\-module\fR" 4
+.IX Item "-gen-module"
+Specify that the output should be a function that regenerates the module. It is
+assumed that this output will be #included into another program that has already
+arranged for the correct header files to be #included. The function generated
+takes no arguments and returns a \fIModule*\fR. 
+.Sp
+If the \fB\-for\fR option is given with this option, it specifies the module
+identifier to use in creating the module returned by the generated function.
+.IP "\fB\-gen\-contents\fR" 4
+.IX Item "-gen-contents"
+Specify that the output should be a function that adds the contents of the input
+module to another module. It is assumed that the output will be #included into
+another program that has already arranged for the correct header files to be
+#included. The function generated takes a single argument of type \fIModule*\fR and
+returns that argument. Note that Module level attributes such as endianess,
+pointer size, target triple and inline asm are not passed on from the input
+module to the destination module. Only the sub-elements of the module (types,
+constants, functions, global variables) will be added to the input module.
+.Sp
+If the \fB\-for\fR option is given with this option, it specifies the module
+identifier to set in the input module by the generated function.
+.IP "\fB\-gen\-function\fR" 4
+.IX Item "-gen-function"
+Specify that the output should be a function that produces the definitions
+necessary for a specific function to be added to a module.  It is assumed that 
+the output will be #included into another program that has already arranged 
+for the correct header files to be #included. The function generated takes a 
+single argument of type \fIModule*\fR and returns the \fIFunction*\fR that it added to
+the module.  Note that only those things (types, constants, etc.) directly 
+needed in the definition of the function will be placed in the generated
+function. 
+.Sp
+The \fB\-for\fR option must be given with this option or an error will be produced.
+The value of the option must be the name of a function in the input module for
+which code should be generated. If the named function does not exist an error
+will be produced.
+.IP "\fB\-gen\-inline\fR" 4
+.IX Item "-gen-inline"
+This option is very analagous to \fB\-gen\-function\fR except that the generated
+function will not re-produce the target function's definition. Instead, the body
+of the target function is inserted into some other function passed as an
+argument to the generated function. Similarly any arguments to the function must
+be passed to the generated function. The result of the generated function is the
+first basic block of the target function.
+.Sp
+The \fB\-for\fR option works the same way as it does for \fB\-gen\-function\fR.
+.IP "\fB\-gen\-variable\fR" 4
+.IX Item "-gen-variable"
+Specify that the output should be a function that produces the definitions
+necessary for a specific global variable to be added to a module. It is assumed
+that the output will be #included into another program that has already arranged
+for the correct header files to be #included. The function generated takes a
+single argument of type \fIModule*\fR and returns the \fIGlobalVariable*\fR that it 
+added to the module. Note that only those things (types, constants, etc.)
+directly needed in the definition of the global variable will be placed in the
+generated function.
+.Sp
+The \fB\-for\fR option must be given with this option or an error will be produced.
+THe value of the option must be the name of a global variable in the input
+module for which code should be generated. If the named global variable does not
+exist an error will be produced.
+.IP "\fB\-gen\-type\fR" 4
+.IX Item "-gen-type"
+Specify that the output should be a function that produces the definitions
+necessary for specific type to be added to a module. It is assumed that the
+otuput will be #included into another program that has already arranged for the
+correct header files to be #included. The function generated take a single
+argument of type \fIModule*\fR and returns the \fIType*\fR that it added to the
+module. Note that the generated function will only add the necessary type
+definitions to (possibly recursively) define the requested type.
+.Sp
+The \fB\-for\fR option must be given with this option or an error will be produced.
+The value of the option must be the name of a global type in the input module
+for which code should be generated. If the named type does not exist an error
+will be produced.
+.IP "\fB\-stats\fR" 4
+.IX Item "-stats"
+Show pass statistics (not interesting in this program).
+.IP "\fB\-time\-passes\fR" 4

+\&\fBllvmc\fR [\fIoptions\fR] [\fIfilenames\fR...]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBllvmc\fR is a configurable driver for invoking other \s-1LLVM\s0 (and non\-LLVM) tools
+in order to compile, optimize and link software for multiple languages. For
+those familiar with \s-1FSF\s0's \fBgcc\fR tool, it is very similar.  Please note that
+\&\fBllvmc\fR is considered an experimental tool.  \fBllvmc\fR has the following goals:
+.IP "* provide a single point of access to the \s-1LLVM\s0 tool set," 4
+.IX Item "provide a single point of access to the LLVM tool set,"
+.PD 0
+.IP "* hide the complexities of the \s-1LLVM\s0 tools through a single interface," 4
+.IX Item "hide the complexities of the LLVM tools through a single interface,"
+.IP "* make integration of existing non-LLVM tools simple," 4
+.IX Item "make integration of existing non-LLVM tools simple,"
+.IP "* extend the capabilities of minimal front ends, and" 4
+.IX Item "extend the capabilities of minimal front ends, and"
+.IP "* make the interface for compiling consistent for all languages." 4
+.IX Item "make the interface for compiling consistent for all languages."
+.PD
+.PP
+The tool itself does nothing with a user's program. It merely invokes other
+tools to get the compilation tasks done.
+.PP
+The options supported by \fBllvmc\fR generalize the compilation process and
+provide a consistent and simple interface for multiple programming languages.
+This makes it easier for developers to get their software compiled with \s-1LLVM\s0.
+Without \fBllvmc\fR, developers would need to understand how to invoke the 
+front-end compiler, optimizer, assembler, and linker in order to compile their 
+programs. \fBllvmc\fR's sole mission is to trivialize that process.
+.Sh "Basic Operation"
+.IX Subsection "Basic Operation"
+\&\fBllvmc\fR always takes the following basic actions:
+.IP "* Command line options and filenames are collected." 4
+.IX Item "Command line options and filenames are collected."
+The command line options provide the marching orders to \fBllvmc\fR on what actions
+it should perform. This is the \fIrequest\fR the user is making of \fBllvmc\fR and it
+is interpreted first.
+.IP "* Configuration files are read." 4
+.IX Item "Configuration files are read."
+Based on the options and the suffixes of the filenames presented, a set of 
+configuration files are read to configure the actions \fBllvmc\fR will take. 
+Configuration files are provided by either \s-1LLVM\s0 or the front end compiler tools
+that \fBllvmc\fR invokes. Users generally don't need to be concerned with the
+contents of the configuration files. 
+.IP "* Determine actions to take." 4
+.IX Item "Determine actions to take."
+The tool chain needed to complete the task is determined. This is the primary 
+work of \fBllvmc\fR. It breaks the request specified by the command line options 
+into a set of basic actions to be done: 
+.RS 4
+.IP "* Pre\-processing: gathering/filtering compiler input (optional)." 4
+.IX Item "Pre-processing: gathering/filtering compiler input (optional)."

+.IP "* Execute actions." 4
+.IX Item "Execute actions."

+The actions determined previously are executed sequentially and then
+\&\fBllvmc\fR terminates.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.Sh "Control Options"
+.IX Subsection "Control Options"
+Control options tell \fBllvmc\fR what to do at a high level. The 
+following control options are defined:
+.IP "\fB\-c\fR or \fB\-\-compile\fR" 4
+.IX Item "-c or --compile"
+This option specifies that the linking phase is not to be run. All
+previous phases, if applicable will run. This is generally how a given
+bytecode file is compiled and optimized for a source language module.
+.IP "\fB\-k\fR or \fB\-\-link\fR or default" 4
+.IX Item "-k or --link or default"
+This option (or the lack of any control option) specifies that all stages
+of compilation, optimization, and linking should be attempted.  Source files
+specified on the command line will be compiled and linked with objects and
+libraries also specified. 
+.IP "\fB\-S\fR" 4
+.IX Item "-S"
+This option specifies that compilation should end in the creation of
+an \s-1LLVM\s0 assembly file that can be later converted to an \s-1LLVM\s0 object
+file.
+.IP "\fB\-E\fR" 4
+.IX Item "-E"
+This option specifies that no compilation or linking should be 
+performed. Only pre\-processing, if applicable to the language being
+compiled, is performed. For languages that support it, this will
+result in the output containing the raw input to the compiler.
+.Sh "Optimization Options"
+.IX Subsection "Optimization Options"
+Optimization with \fBllvmc\fR is based on goals and specified with
+the following \-O options. The specific details of which
+optimizations run is controlled by the configuration files because
+each source language will have different needs. 
+.IP "\fB\-O1\fR or \fB\-O0\fR (default, fast compilation)" 4
+.IX Item "-O1 or -O0 (default, fast compilation)"
+Only those optimizations that will hasten the compilation (mostly by reducing
+the output) are applied. In general these are extremely fast and simple 
+optimizations that reduce emitted code size. The goal here is not to make the 
+resulting program fast but to make the compilation fast.  If not specified, 
+this is the default level of optimization.
+.IP "\fB\-O2\fR (basic optimization)" 4
+.IX Item "-O2 (basic optimization)"
+This level of optimization specifies a balance between generating good code 
+that will execute reasonably quickly and not spending too much time optimizing
+the code to get there. For example, this level of optimization may include 
+things like global common subexpression elimination, aggressive dead code 
+elimination, and scalar replication.
+.IP "\fB\-O3\fR (aggressive optimization)" 4
+.IX Item "-O3 (aggressive optimization)"
+This level of optimization aggressively optimizes each set of files compiled 
+together. However, no link-time inter-procedural optimization is performed.
+This level implies all the optimizations of the \fB\-O1\fR and \fB\-O2\fR optimization
+levels, and should also provide loop optimizations and compile time 
+inter-procedural optimizations. Essentially, this level tries to do as much
+as it can with the input it is given but doesn't do any link time \s-1IPO\s0.
+.IP "\fB\-O4\fR (link time optimization)" 4
+.IX Item "-O4 (link time optimization)"
+In addition to the previous three levels of optimization, this level of 
+optimization aggressively optimizes each program at link time. It employs
+basic analysis and basic link-time inter-procedural optimizations, 
+considering the program as a whole.
+.IP "\fB\-O5\fR (aggressive link time optimization)" 4
+.IX Item "-O5 (aggressive link time optimization)"
+This is the same as \fB\-O4\fR except it employs aggressive analyses and
+aggressive inter-procedural optimization. 
+.IP "\fB\-O6\fR (profile guided optimization: not implemented)" 4
+.IX Item "-O6 (profile guided optimization: not implemented)"
+This is the same as \fB\-O5\fR except that it employs profile-guided
+re-optimization of the program after it has executed. Note that this implies
+a single level of re-optimization based on runtime profile analysis. Once
+the re-optimization has completed, the profiling instrumentation is
+removed and final optimizations are employed.
+.IP "\fB\-O7\fR (lifelong optimization: not implemented)" 4
+.IX Item "-O7 (lifelong optimization: not implemented)"
+This is the same as \fB\-O5\fR and similar to \fB\-O6\fR except that re-optimization
+is performed through the life of the program. That is, each run will update
+the profile by which future re-optimizations are directed.
+.Sh "Input Options"
+.IX Subsection "Input Options"
+.IP "\fB\-l\fR \fI\s-1LIBRARY\s0\fR" 4
+.IX Item "-l LIBRARY"
+This option instructs \fBllvmc\fR to locate a library named \fI\s-1LIBRARY\s0\fR and search
+it for unresolved symbols when linking the program.
+.IP "\fB\-L\fR \fIpath\fR" 4
+.IX Item "-L path"
+This option instructs \fBllvmc\fR to add \fIpath\fR to the list of places in which
+the linker will
+.IP "\fB\-x\fR \fI\s-1LANGUAGE\s0\fR" 4
+.IX Item "-x LANGUAGE"
+This option instructs \fBllvmc\fR to regard the following input files as 
+containing programs in the language \fI\s-1LANGUAGE\s0\fR. Normally, input file languages
+are identified by their suffix but this option will override that default
+behavior. The \fB\-x\fR option stays in effect until the end of the options or
+a new \fB\-x\fR option is encountered.
+.Sh "Output Options"
+.IX Subsection "Output Options"
+.IP "\fB\-m\fR\fIarch\fR" 4
+.IX Item "-march"
+This option selects the back end code generator to use. The \fIarch\fR portion
+of the option names the back end to use.
+.IP "\fB\-\-native\fR" 4
+.IX Item "--native"
+Normally, \fBllvmc\fR produces bytecode files at most stages of compilation.
+With this option, \fBllvmc\fR will arrange for native object files to be
+generated with the \fB\-c\fR option, native assembly files to be generated
+with the \fB\-S\fR option, and native executables to be generated with the
+\&\fB\-\-link\fR option. In the case of the \fB\-E\fR option, the output will not
+differ as there is no \fInative\fR version of pre-processed output.
+.IP "\fB\-o\fR \fIfilename\fR" 4
+.IX Item "-o filename"
+Specify the output file name.  The contents of the file  depend on other 
+options. 
+.Sh "Information Options"
+.IX Subsection "Information Options"
+.IP "\fB\-n\fR or \fB\-\-no\-op\fR" 4
+.IX Item "-n or --no-op"
+This option tells \fBllvmc\fR to do everything but actually execute the
+resulting tools. In combination with the \fB\-v\fR option, this causes \fBllvmc\fR
+to merely print out what it would have done.
+.IP "\fB\-v\fR or \fB\-\-verbose\fR" 4
+.IX Item "-v or --verbose"
+This option will cause \fBllvmc\fR to print out (on standard output) each of the 
+actions it takes to accomplish the objective. The output will immediately
+precede the invocation of other tools.
+.IP "\fB\-\-stats\fR" 4
+.IX Item "--stats"
+Print all statistics gathered during the compilation to the standard error. 
+Note that this option is merely passed through to the sub-tools to do with 
+as they please.
+.IP "\fB\-\-time\-passes\fR" 4
+.IX Item "--time-passes"
+Record the amount of time needed for each optimization pass and print it 
+to standard error. Like \fB\-\-stats\fR this option is just passed through to
+the sub-tools to do with as they please.
+.IP "\fB\-\-time\-programs\fR" 4
+.IX Item "--time-programs"
+Record the amount of time each program (compilation tool) takes and print
+it to the standard error. 
+.Sh "Language Specific Options"
+.IX Subsection "Language Specific Options"
+.IP "\fB\-T,pre\fR=\fIoptions\fR" 4
+.IX Item "-T,pre=options"
+Pass an arbitrary option to the pre\-processor.
+.IP "\fB\-T,opt\fR=\fIoptions\fR" 4
+.IX Item "-T,opt=options"
+Pass an arbitrary option to the optimizer.
+.IP "\fB\-T,lnk\fR=\fIoptions\fR" 4
+.IX Item "-T,lnk=options"
+Pass an arbitrary option to the linker.
+.IP "\fB\-T,asm\fR=\fIoptions\fR" 4
+.IX Item "-T,asm=options"
+Pass an arbitrary option to the code generator.
+.Sh "C/\*(C+ Specific Options"
+.IX Subsection "C/ Specific Options"
+.IP "\fB\-I\fR\fIpath\fR" 4
+.IX Item "-Ipath"
+This option is just passed through to a C or \*(C+ front end compiler to tell it
+where include files can be found.
+.IP "\fB\-D\fR\fIsymbol\fR" 4
+.IX Item "-Dsymbol"
+This option is just passed through to a C or \*(C+ front end compiler to tell it
+to define a symbol.
+.Sh "Miscellaneous Options"
+.IX Subsection "Miscellaneous Options"
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+Print a summary of command line options.
+.IP "\fB\-\-version\fR" 4
+.IX Item "--version"
+This option will cause \fBllvmc\fR to print out its version number and terminate.
+.Sh "Advanced Options"
+.IX Subsection "Advanced Options"
+You better know what you're doing if you use these options. Improper use
+of these options can produce drastically wrong results.
+.IP "\fB\-\-config\-dir\fR \fIdirname\fR" 4
+.IX Item "--config-dir dirname"
+This option tells \fBllvmc\fR to read configuration data from the \fIdirectory\fR
+named \fIdirname\fR. Data from such directories will be read in the order
+specified on the command line after all other standard configuration files have
+been read. This allows users or groups of users to conveniently create 
+their own configuration directories in addition to the standard ones to which 
+they may not have write access.
+.Sh "Unimplemented Options"
+.IX Subsection "Unimplemented Options"
+The options below are not currently implemented in \fBllvmc\fR but will be
+eventually. They are documented here as \*(L"future design\*(R".
+.IP "\fB\-\-show\-config\fR \fI[suffixes...]\fR" 4
+.IX Item "--show-config [suffixes...]"
+When this option is given, the only action taken by \fBllvmc\fR is to show its
+final configuration state in the form of a configuration file. No compilation
+tasks will be conducted when this option is given; processing will stop once
+the configuration has been printed. The optional (comma separated) list of 
+suffixes controls what is printed. Without any suffixes, the configuration
+for all languages is printed. With suffixes, only the languages pertaining
+to those file suffixes will be printed. The configuration information is
+printed after all command line options and configuration files have been
+read and processed. This allows the user to verify that the correct
+configuration data has been read by \fBllvmc\fR.
+.IP "\fB\-\-config\fR :\fIsection\fR:\fIname\fR=\fIvalue\fR" 4
+.IX Item "--config :section:name=value"
+This option instructs \fBllvmc\fR to accept \fIvalue\fR as the value for configuration
+item \fIname\fR in the section named \fIsection\fR. This is a quick way to override
+a configuration item on the command line without resorting to changing the
+configuration files. 
+.IP "\fB\-\-config\-only\-from\fR \fIdirname\fR" 4
+.IX Item "--config-only-from dirname"
+This option tells \fBllvmc\fR to skip the normal processing of configuration
+files and only configure from the contents of the \fIdirname\fR directory. Multiple
+\&\fB\-\-config\-only\-from\fR options may be given in which case the directories are
+read in the order given on the command line.
+.IP "\fB\-\-emit\-raw\-code\fR" 4
+.IX Item "--emit-raw-code"
+No optimization is done whatsoever. The compilers invoked by \fBllvmc\fR with 
+this option given will be instructed to produce raw, unoptimized code.  This 
+option is useful only to front end language developers and therefore does not 
+participate in the list of \fB\-O\fR options. This is distinctly different from
+the \fB\-O0\fR option (a synonym for \fB\-O1\fR) because those optimizations will
+reduce code size to make compilation faster. With \fB\-\-emit\-raw\-code\fR, only
+the full raw code produced by the compiler will be generated.
+.SH "EXIT STATUS"
+.IX Header "EXIT STATUS"
+If \fBllvmc\fR succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value and no compilation actions
+will be taken. If one of the compilation tools returns a non-zero 
+status, pending actions will be discarded and \fBllvmc\fR will return the
+same result code as the failing compilation tool.
+.SH "DEFICIENCIES"
+.IX Header "DEFICIENCIES"
+\&\fBllvmc\fR is considered an experimental \s-1LLVM\s0 tool because it has these
+deficiencies: 
+.IP "Insufficient support for native linking" 4
+.IX Item "Insufficient support for native linking"
+Because \fBllvm-ld\fR doesn't handle native linking, neither can \fBllvmc\fR
+.IP "Poor configuration support" 4
+.IX Item "Poor configuration support"
+The support for configuring new languages, etc. is weak. There are many
+command line configurations that cannot be achieved with the current
+support. Furthermore the grammar is cumbersome for configuration files.
+Please see <http://llvm.org/PR686> for further details.

+.IX Header "DESCRIPTION"
+The \fBllvm-gcc\fR command is the \s-1LLVM\s0 C front end.  It is a modified
+version of gcc that compiles C/ObjC programs into native objects, \s-1LLVM\s0
+bytecode or \s-1LLVM\s0 assembly language, depending upon the options.
+.PP
+By default, \fBllvm-gcc\fR compiles to native objects just like \s-1GCC\s0 does. If the
+\&\fB\-emit\-llvm\fR option is given then it will generate \s-1LLVM\s0 bytecode files instead.
+If \fB\-S\fR (assembly) is also given, then it will generate \s-1LLVM\s0 assembly. 
+.PP
+Being derived from the \s-1GNU\s0 Compiler Collection, \fBllvm-gcc\fR has many
+of gcc's features and accepts most of gcc's options.  It handles a
+number of gcc's extensions to the C programming language.

+.IX Header "DESCRIPTION"
+The \fBllvm\-g++\fR command is the \s-1LLVM\s0 \*(C+ front end.  It is a modified
+version of g++ that compiles \*(C+/ObjC++ programs into native code, 
+\&\s-1LLVM\s0 bytecode or assembly language, depending upon the options.
+.PP
+By default, \fBllvm\-g++\fR compiles to native objects just like \s-1GCC\s0 does. If the
+\&\fB\-emit\-llvm\fR option is given then it will generate \s-1LLVM\s0 bytecode files instead.
+If \fB\-S\fR (assembly) is also given, then it will generate \s-1LLVM\s0 assembly. 
+.PP
+Being derived from the \s-1GNU\s0 Compiler Collection, \fBllvm\-g++\fR has many
+of g++'s features and accepts most of g++'s options.  It handles a
+number of g++'s extensions to the \*(C+ programming language.

+opt \- LLVM optimizer
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+\&\fBopt\fR [\fIoptions\fR] [\fIfilename\fR]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBopt\fR command is the modular \s-1LLVM\s0 optimizer and analyzer.  It takes \s-1LLVM\s0 
+bytecode as input, runs the specified optimizations or analyses on it, and then
+outputs the optimized \s-1LLVM\s0 bytecode or the analysis results.  The function of 
+\&\fBopt\fR depends on whether the \fB\-analyze\fR option is given. 
+.PP
+When \fB\-analyze\fR is specified, \fBopt\fR performs various analyses of \s-1LLVM\s0 
+bytecode.  It will usually print the results on standard output, but in a few 
+cases, it will print output to standard error or generate a file with the 
+analysis output, which is usually done when the output is meant for another 
+program.  
+.PP
+While \fB\-analyze\fR is \fInot\fR given, \fBopt\fR attempts to produce an optimized 
+bytecode file.  The optimizations available via \fBopt\fR depend upon what 
+libraries were linked into it as well as any additional libraries that have 
+been loaded with the \fB\-load\fR option.  Use the \fB\-help\fR option to determine 
+what optimizations you can use.
+.PP
+If \fIfilename\fR is omitted from the command line or is \fI\-\fR, \fBopt\fR reads its
+input from standard input. The input must be an \s-1LLVM\s0 bytecode file.
+.PP
+If an output filename is not specified with the \fB\-o\fR option, \fBopt\fR
+writes its output to the standard output.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Force overwrite.  Normally, \fBopt\fR will refuse to overwrite an
+output file that already exists.  With this option, \fBopt\fR will
+overwrite the output file and replace it with new bytecode.
+.IP "\fB\-help\fR" 4
+.IX Item "-help"
+Print a summary of command line options. 
+.IP "\fB\-o\fR \fIfilename\fR" 4
+.IX Item "-o filename"
+Specify the output filename.
+.IP "\fB\-{passname}\fR" 4
+.IX Item "-{passname}"
+\&\fBopt\fR provides the ability to run any of \s-1LLVM\s0's optimization or analysis passes
+in any order. The \fB\-help\fR option lists all the passes available. The order in
+which the options occur on the command line are the order in which they are
+executed (within pass constraints). 
+.IP "\fB\-std\-compile\-opts\fR" 4
+.IX Item "-std-compile-opts"
+This is short hand for a standard list of \fIcompile time optimization\fR passes.
+This is typically used to optimize the output from the llvm-gcc front end. It
+might be useful for other front end compilers as well. To discover the full set
+of options available, use the following command:
+.Sp
+.Vb 1
+\&   llvm-as < /dev/null | opt -std-compile-opts -disable-output -debug-pass=Arguments
+.Ve
+.IP "\fB\-disable\-inlining\fR" 4
+.IX Item "-disable-inlining"
+This option is only meaningful when \fB\-std\-compile\-opts\fR is given. It simply
+removes the inlining pass from the standard list.
+.IP "\fB\-disable\-opt\fR" 4
+.IX Item "-disable-opt"
+This option is only meaningful when \fB\-std\-compile\-opts\fR is given. It disables
+most, but not all, of the \fB\-std\-compile\-opts\fR. The ones that remain are
+\&\fB\-verify\fR, \fB\-lower\-setjmp\fR, and \fB\-funcresolve\fR.
+.IP "\fB\-strip\-debug\fR" 4
+.IX Item "-strip-debug"
+This option causes opt to strip debug information from the module before 
+applying other optimizations. It is essentially the same as \fB\-strip\fR but it
+ensures that stripping of debug information is done first.
+.IP "\fB\-verify\-each\fR" 4
+.IX Item "-verify-each"
+This option causes opt to add a verify pass after every pass otherwise specified
+on the command line (including \fB\-verify\fR).  This is useful for cases where it 
+is suspected that a pass is creating an invalid module but it is not clear which
+pass is doing it. The combination of \fB\-std\-compile\-opts\fR and \fB\-verify\-each\fR
+can quickly track down this kind of problem.
+.IP "\fB\-profile\-info\-file\fR \fIfilename\fR" 4
+.IX Item "-profile-info-file filename"
+Specify the name of the file loaded by the \-profile\-loader option.
+.IP "\fB\-stats\fR" 4
+.IX Item "-stats"
+Print statistics.
+.IP "\fB\-time\-passes\fR" 4
+.IX Item "-time-passes"
+Record the amount of time needed for each pass and print it to standard
+error.
+.IP "\fB\-debug\fR" 4
+.IX Item "-debug"
+If this is a debug build, this option will enable debug printouts
+from passes which use the \fI\s-1\fIDEBUG\s0()\fI\fR macro.  See the \fB\s-1LLVM\s0 Programmer's
+Manual\fR, section \fI#DEBUG\fR for more information.
+.IP "\fB\-load\fR=\fIplugin\fR" 4
+.IX Item "-load=plugin"
+Load the dynamic object \fIplugin\fR.  This object should register new optimization
+or analysis passes. Once loaded, the object will add new command line options to
+enable various optimizations or analyses.  To see the new complete list of 
+optimizations, use the \fB\-help\fR and \fB\-load\fR options together. For example:
+.Sp

+stkrc \- Stacker Compiler
+.SH "SYNOPSIS"
+.IX Header "SYNOPSIS"
+\&\fBstkrc\fR [\fIoptions\fR] [\fIfilename\fR]
+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The \fBstkrc\fR command is the compiler for the Stacker language. Stacker is a
+simple stack based, Forth-like language that was written as a demonstration
+language for \s-1LLVM\s0. For details on the language, please see
+<http://llvm.org/docs/Stacker.html> . The \fBstkrc\fR compiler is fairly 
+minimal. It compiles to bytecode only and doesn't perform any optimizations.
+The output of stkrc (a bytecode file) can be piped through other \s-1LLVM\s0 tools
+for optimization and linking.
+.PP
+If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBstkrc\fR reads its input 
+from standard input. This is useful for combining the tool into a pipeline.
+.PP
+If an output file is not specified with the \fB\-o\fR option, then
+\&\fBllvm-as\fR sends its output to a file or standard output by following
+these rules:
+.IP "\(bu" 4
+If the input is standard input, then the output is standard output.
+.IP "\(bu" 4
+If the input is a file that ends with \f(CW\*(C`.st\*(C'\fR, then the output file is of
+the same name, except that the suffix is changed to \f(CW\*(C`.bc\*(C'\fR.
+.IP "\(bu" 4
+If the input is a file that does not end with the \f(CW\*(C`.st\*(C'\fR suffix, then the
+output file has the same name as the input file, except that the \f(CW\*(C`.bc\*(C'\fR
+suffix is appended.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-o\fR \fIfilename\fR" 4
+.IX Item "-o filename"
+Specify the output file name.  If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR
+sends its output to standard output.
+.IP "\fB\-stats\fR" 4
+.IX Item "-stats"
+Print statistics acquired during compilation.
+.IP "\fB\-time\-passes\fR" 4
+.IX Item "-time-passes"
+Record the amount of time needed for each pass and print it to standard
+error.
+.IP "\fB\-f\fR" 4
+.IX Item "-f"
+Force the output to be written. Normally, \fBstkrc\fR won't overwrite an existing
+bytecode file. This option overrides that behavior. 
+.IP "\fB\-s\fR \fIstacksize\fR" 4
+.IX Item "-s stacksize"
+Specify the stack size for the program. The default stack size, 1024, should be
+sufficient for most programs. For very large programs, especially those that 
+recurse a lot, you might want to provide a larger value. Each unit of this
+value consumes 8 bytes of memory.
+.IP "\fB\-help\fR" 4
+.IX Item "-help"
+Print a summary of command line options.
+.SH "EXIT STATUS"
+.IX Header "EXIT STATUS"
+If \fBstkrc\fR succeeds, it will exit with 0.  Otherwise, if an error
+occurs, it will exit with a non-zero value, usually 1.

-</p>
+<p>This is the eleventh public release of the LLVM Compiler Infrastructure. 
+Being the first major release since 1.0, this release is different in several
+ways from our previous releases:</p>
+
+<ol>
+<li>We took this as an opportunity to
+break backwards compatibility with the LLVM 1.x bytecode and .ll file format.
+If you have LLVM 1.9 .ll files that you would like to upgrade to LLVM 2.x, we 
+recommend the use of the stand alone <a href="#llvm-upgrade">llvm-upgrade</a>
+tool (which is included with 2.0).  We intend to keep compatibility with .ll 
+and .bc formats within the 2.x release series, like we did within the 1.x 
+series.</li>
+<li>There are several significant change to the LLVM IR and internal APIs, such
+    as a major overhaul of the type system, the completely new bitcode file
+    format, etc (described below).</li>
+<li>We designed the release around a 6 month release cycle instead of the usual
+    3-month cycle.  This gave us extra time to develop and test some of the
+    more invasive features in this release.</li>
+<li>LLVM 2.0 no longer supports the llvm-gcc3 front-end.  Users are required to
+    upgrade to llvm-gcc4.  llvm-gcc4 includes many features over
+    llvm-gcc3, is faster, and is <a href="CFEBuildInstrs.html">much easier to
+    build from source</a>.</li>
+</ol>
+
+<p>Note that while this is a major version bump, this release has been
+   extensively tested on a wide range of software.  It is easy to say that this
+   is our best release yet, in terms of both features and correctness.  This is
+   the first LLVM release to correctly compile and optimize major software like
+   LLVM itself, Mozilla/Seamonkey, Qt 4.3rc1, kOffice, etc out of the box on
+   linux/x86.

-<div class="doc_text">
-<p>LLVM now includes <a href="LinkTimeOptimization.html">liblto</a> which can
-be used to integrate LLVM Link-Time Optimization support into a native linker.
-This allows LLVM .bc to transparently participate with linking an application,
-even when some .o files are in LLVM form and some are not.</p>
+<p>Changes to the LLVM IR itself:</p>
+
+<ul>
+
+<li>Integer types are now completely signless. This means that we
+    have types like i8/i16/i32 instead of ubyte/sbyte/short/ushort/int
+    etc. LLVM operations that depend on sign have been split up into 
+    separate instructions (<a href="http://llvm.org/PR950">PR950</a>).  This
+    eliminates cast instructions that just change the sign of the operands (e.g.
+    int -> uint), which reduces the size of the IR and makes optimizers
+    simpler to write.</li>
+
+<li>Integer types with arbitrary bitwidths (e.g. i13, i36, i42, i1057, etc) are
+    now supported in the LLVM IR and optimizations (<a 
+    href="http://llvm.org/PR1043">PR1043</a>).  However, neither llvm-gcc
+    (<a href="http://llvm.org/PR1284">PR1284</a>) nor the native code generators
+    (<a href="http://llvm.org/PR1270">PR1270</a>) support non-standard width
+    integers yet.</li>
+
+<li>'Type planes' have been removed (<a href="http://llvm.org/PR411">PR411</a>).
+    It is no longer possible to have two values with the same name in the 
+    same symbol table.  This simplifies LLVM internals, allowing significant 
+    speedups.</li>
+
+<li>Global variables and functions in .ll files are now prefixed with
+    @ instead of % (<a href="http://llvm.org/PR645">PR645</a>).</li>
+
+<li>The LLVM 1.x "bytecode" format has been replaced with a  
+    completely new binary representation, named 'bitcode'. The <a
+    href="BitCodeFormat.html">Bitcode Format</a> brings a
+    number of advantages to the LLVM over the old bytecode format: it is denser  
+    (files are smaller), more extensible, requires less memory to read,  
+    is easier to keep backwards compatible (so LLVM 2.5 will read 2.0 .bc  
+    files), and has many other nice features.</li>
+
+<li>Load and store instructions now track the alignment of their pointer
+    (<a href="http://www.llvm.org/PR400">PR400</a>).  This allows the IR to
+    express loads that are not sufficiently aligned (e.g. due to '<tt>#pragma
+    packed</tt>') or to capture extra alignment information.</li>
+</ul>
+
+<p>Major new features:</p>
+
+<ul>
+
+<li>A number of ELF features are now supported by LLVM, including 'visibility',
+    extern weak linkage, Thread Local Storage (TLS) with the <tt>__thread</tt>
+    keyword, and symbol aliases.
+    Among other things, this means that many of the special options needed to
+    configure llvm-gcc on linux are no longer needed, and special hacks to build
+    large C++ libraries like Qt are not needed.</li>
+
+<li>LLVM now has a new MSIL backend. <tt>llc -march=msil</tt> will now turn LLVM
+    into MSIL (".net") bytecode.  This is still fairly early development 
+    with a number of limitations.</li>
+
+<li>A new <a href="CommandGuide/html/llvm-upgrade.html">llvm-upgrade</a> tool 
+    exists to migrates LLVM 1.9 .ll files to LLVM 2.0 syntax.</li>

-<li>The register coalescer is now more aggressive than before,  
-     allowing it to eliminate more copies.</li>
+
+<li>LLVM now supports software floating point, which allows LLVM to target
+    chips that don't have hardware FPUs (e.g. ARM thumb mode).</li>
+
+<li>A new register scavenger has been implemented, which is useful for
+    finding free registers after register allocation.  This is useful when
+    rewriting frame references on RISC targets, for example.</li>
+
+<li>Heuristics have been added to avoid coalescing vregs with very large live 
+    ranges to physregs.  This was bad because it effectively pinned the physical
+    register for the entire lifetime of the virtual register (<a 
+    href="http://llvm.org/PR711">PR711</a>).</li>
+
+<li>Support now exists for very simple (but still very useful) 
+    rematerialization the register allocator, enough to move  
+    instructions like "load immediate" and constant pool loads.</li>
+
+<li>Switch statement lowering is significantly better, improving codegen for 
+    sparse switches that have dense subregions, and implemented support 
+    for the shift/and trick.</li>
+
+<li>LLVM now supports tracking physreg sub-registers and super-registers 
+    in the code generator, and includes extensive register
+    allocator changes to track them.</li>
+
+<li>There is initial support for virtreg sub-registers 
+    (<a href="http://llvm.org/PR1350">PR1350</a>).</li>
+
+</ul>
+
+<p>
+Other improvements include:
+</p>
+
+<ul>
+
+<li>Inline assembly support is much more solid that before.
+    The two primary features still missing are support for 80-bit floating point
+    stack registers on X86 (<a href="http://llvm.org/PR879">PR879</a>), and
+    support for inline asm in the C backend (<a 
+    href="http://llvm.org/PR802">PR802</a>).</li>
+
+<li>DWARF debug information generation has been improved.  LLVM now passes 
+    most of the GDB testsuite on MacOS and debug info is more dense.</li>
+
+<li>Codegen support for Zero-cost DWARF exception handling has been added (<a 
+    href="http://llvm.org/PR592">PR592</a>).  It is mostly
+    complete and just in need of continued bug fixes and optimizations at 
+    this point.  However, support in llvm-g++ is disabled with an
+    #ifdef for the 2.0 release  (<a 
+    href="http://llvm.org/PR870">PR870</a>).</li>
+
+<li>The code generator now has more accurate and general hooks for  
+    describing addressing modes ("isLegalAddressingMode") to  
+    optimizations like loop strength reduction and code sinking.</li>
+
+<li>Progress has been made on a direct Mach-o .o file writer. Many small 
+    apps work, but it is still not quite complete.</li>
+
 </ul>
 
 <p>In addition, the LLVM target description format has itself been extended in
  several ways:</p>
  
 <ul>
-<li>tblgen now allows definition of '<a 
-     href="TableGenFundamentals.html#multiclass">multiclasses</a>' which can be
-     used to factor instruction patterns more aggressively in .td files.</li>
-<li>LLVM has a new TargetAsmInfo class which captures a variety of
-     information about the target assembly language format.</li>
-<li>.td files now support "<tt>${:foo}</tt>" syntax for encoding 
-     subtarget-specific assembler syntax into instruction descriptions.</li>
+<li>TargetData now supports better target parameterization in
+    the .ll/.bc files, eliminating the 'pointersize/endianness' attributes
+    in the files (<a href="http://llvm.org/PR761">PR761</a>).</li>
+
+<li>TargetData was generalized for finer grained alignment handling,
+    handling of vector alignment, and handling of preferred alignment</li>
+
+<li>LLVM now supports describing target calling conventions  
+    explicitly in .td files, reducing the amount of C++ code that needs  
+    to be written for a port.</li>
