2011-08-17Allow the MCDisassembler to return a "soft fail" status code, indicating an ↵Owen Anderson
instruction that is disassemblable, but invalid. Only used for ARM UNPREDICTABLE instructions at the moment. Patch by James Molloy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137830 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-15Avoid evaluating Neon macro arguments more than once by disabling type checks.Bob Wilson
It turns out that the use of "__extension__" in these macros was disabling the expected "incompatible pointer" warnings, so these type checks were not doing anything anyway. They introduced a serious bug by evaluating some macro arguments twice, which is a big problem for arguments with side effects. I'll have to find another way to get the right type checking. Radar 9947657. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137680 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-15MCTargetAsmParser target match predicate support.Jim Grosbach
Allow a target assembly parser to do context sensitive constraint checking on a potential instruction match. This will be used, for example, to handle Thumb2 IT block parsing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137675 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-15Move MatchResultTy enum into base class definition.Jim Grosbach
No need for it to be redefined as part of every derived target asm parser class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137649 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-10Make Record Name an InitDavid Greene
Use an Init (ultimately a StringInit) to represent the Record name. This allows the name to be composed by standard TableGen operators. This will enable us to get rid of the ugly #NAME# hack processing and naturally replace it with operators. It also increases flexibility and power of the TableGen language by allowing record identifiers to be computed dynamically. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137232 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-10Add getAsUnquotedStringDavid Greene
Add a method to return an Init as an unquoted string. This primarily affects StringInit where we return the value without surrounding it with quotes. This is in preparation for removing the ugly #NAME# hack and replacing it with standard TabelGen operators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137231 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Fix an oversight in the FixedLenDecoderEmitter where we weren't correctly ↵Owen Anderson
checking the success result of custom decoder hooks on singleton decodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137171 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Create a new register class for the set of all GPRs except the PC. Use it ↵Owen Anderson
to tighten our decoding of BFI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137168 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Replace the existing ARM disassembler with a new one based on the ↵Owen Anderson
FixedLenDecoderEmitter. This new disassembler can correctly decode all the testcases that the old one did, though some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in operand checking as the old one was. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137144 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-08Fix encodings for Thumb ASR and LSR immediate operands. They encode the ↵Owen Anderson
range 1-32, with 32 encoded as 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137062 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-04LDCL_POST and STCL_POST need one's-complement offsets, rather than two's ↵Owen Anderson
complement offsets. Add an appropriate immediate type for them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136896 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-03ARM refactoring assembly parsing of memory address operands.Jim Grosbach
Memory operand parsing is a bit haphazzard at the moment, in no small part due to the even more haphazzard representations of memory operands in the .td files. Start cleaning that all up, at least a bit. The addressing modes in the .td files will be being simplified to not be so monolithic, especially with regards to immediate vs. register offsets and post-indexed addressing. addrmode3 is on its way with this patch, for example. This patch is foundational to enable going back to smaller incremental patches for the individual memory referencing instructions themselves. It does just enough to get the basics in place and handle the "make check" regression tests we already have. Follow-up work will be fleshing out the details and adding more robust test cases for the individual instructions, starting with ARM mode and moving from there into Thumb and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136845 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-02ARM: rename addrmode7 to addr_offset_none.Jim Grosbach
Use a more descriptive name so the code is more self-documenting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136704 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-01Make the FixedLengthDecoderEmitter smart enough to autogenerate decoders for ↵Owen Anderson
encodings like "let Inst{11-7} = foo;", where the RHS has no bitwidth specifiers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136660 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-01The FixedLenDecoder needs to gracefully handle failing per-instruction ↵Owen Anderson
decoder hooks in addition to per-operand decoder hooks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136645 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29[AVX] Make TernOpInit UniqueDavid Greene
Make sure TernOpInits are unique and created only once. This will be important for AVX/SIMD as many operators will be used to generate patterns and other relevant data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136496 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29[AVX] Make ListInits UniqueDavid Greene
Ensure ListInits are unique and only created once. This will be important for AVX as lists will be used extensively to pass generic patterns, prefix information and other things to lower-level pattern-generation classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136493 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make CodeInit UniqueDavid Greene
Use a StringMap to ensure CodeInits are unique and created only once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136492 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make StringInit UniqueDavid Greene
Use a StringMap to ensure the StringInits are unique. This is especially important for AVX where we will have many smallish strings representing instruction prefixes, suffixes and the like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136491 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make IntInit UniqueDavid Greene
Use a DenseMap to make sure only one IntInit of any value exists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136490 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Make BitsInit UniqueDavid Greene
Make BitsInit a FoldingSetNode so we can unique it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136489 91177308-0d34-0410-b5e6-96231b3b80d8

Keep only two copies of BitInit: one for true and one for false. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136488 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Unique UnsetInitDavid Greene
Keep only one UnsetInit around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136487 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Create Inits Via Factory MethodDavid Greene
Replace uses of new *Init with *Init::get. This hides the allocation implementation so that we can unique Inits in various ways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136486 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Constify InitsDavid Greene
Make references to Inits const everywhere. This is the final step before making them unique. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136485 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29[AVX] Remove non-const IteratorsDavid Greene
Remove all non-const iterators from Init classes. This is another step toward constifying Inits and ultimately turning them into FoldingSetNodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136484 91177308-0d34-0410-b5e6-96231b3b80d8

Get rid of all Init members that modify internal state. This is in preparation for making references to Inits const. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136483 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Add ListInit::getValuesDavid Greene
Add a getValues ListInit method to return the sequence of values in the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136482 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-29Add a std::string Wrapper for TableGenDavid Greene
Create a std::string wrapper for use as a DenseMap key. DenseMap is not safe in generate with strings, so this wrapper indicates that only strings guaranteed not to have certain values should be used in the DenseMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136481 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-27Emit an error is asm parser parsed X86_64 only registers, e.g. %rax, %sil.Evan Cheng
This can happen in cases where TableGen generated asm matcher cannot check whether a register operand is in the right register class. e.g. mem operands. rdar://8204588 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136292 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-27Fix llvm-mc handing of x86 instructions that take 8-bit unsigned immediates.Kevin Enderby
llvm-mc gives an "invalid operand" error for instructions that take an unsigned immediate which have the high bit set such as: pblendw $0xc5, %xmm2, %xmm1 llvm-mc treats all x86 immediates as signed values and range checks them. A small number of x86 instructions use the imm8 field as a set of bits. This change only changes those instructions and where the high bit is not ignored. The others remain unchanged. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136287 91177308-0d34-0410-b5e6-96231b3b80d8
