2009-12-17Test harness for the LLVM disassembler. When invokedSean Callanan
with -disassemble, llvm-mc now accepts lines of the form 0x00 0x00 and passes the resulting bytes to the disassembler for the chosen (or default) target, printing the result. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91579 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-16MC: When parsing a variable reference, substitute absolute variables immediatelyDaniel Dunbar
since they are allowed to be redefined. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84230 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27add a new DirectiveMap stringmap, which allows more efficient dispatchingChris Lattner
to directive handlers and allows for easier extensibility. I only switched a few over for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82926 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-20Add an intel syntax MCInstPrinter implementation. You can nowChris Lattner
transcode from AT&T to intel syntax with "llvm-mc foo.s -output-asm-variant=1" git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-16Fixed some problems with the logic of parsing line comments by addingKevin Enderby
isAtStartOfComment and using that instead in two places where a loop to check if the char was in MAI.getCommentString(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82059 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-16use an accessor to simplify code.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81997 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-14Change MCAsmStreamer to take an MCInstPrinter instead of a Chris Lattner
full AsmPrinter, and change TargetRegistry to keep track of registered MCInstPrinters. llvm-mc is still linking in the entire target foo to get the code emitter stuff, but this is an important step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81754 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-10Added the ParseInstruction() hook for target specific assembler directives soKevin Enderby
that things like .word can be parsed as target specific. Moved parsing .word out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes for other targets that support the .word directive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81461 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-04Added AsmToken enum constants to MCAsmLexer.h for '[', ']', '{', and '}' inKevin Enderby
preparation of supporting other targets. Then changed the lexer to parse these as tokens. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81050 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-04Added the AsmToken::Hash enum constant to MCAsmLexer.h in preparation ofKevin Enderby
supporting other targets. Changed the code to pass MCAsmInfo to the parser and the lexer. Then changed the lexer to use CommentString from MCAsmInfo instead of a literal '#' character. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81046 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Removed the non-target independent AsmToken::Register enum constantKevin Enderby
from MCAsmLexer.h in preparation of supporting other targets. Changed the X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking for AsmToken::Percent when parsing in places that used AsmToken::Register. Then changed X86ATTAsmParser::ParseRegister to parse out registers as an AsmToken::Percent followed by an AsmToken::Identifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80929 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-26llvm-mc/Mach-O: Unique sections properly, so we don't get duplicate textDaniel Dunbar
sections, etc. - The quick and dirty way, just clone the TargetLoweringObjectFile code. Eventually this should be shared... somehow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80168 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-26llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.Daniel Dunbar
- I moved section creation back into AsmParser. I think policy decisions like this should be pushed higher, not lower, when possible (in addition the assembler has flags which change this behavior, for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80162 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-25Make LLVM command-line tools overwrite their output files without -f.Dan Gohman
This is conventional command-line tool behavior. -f now just means "enable binary output on terminals". Add a -f option to llvm-extract and llvm-link, for consistency. Remove F_Force from raw_fd_ostream and enable overwriting and truncating by default. Introduce an F_Excl flag to permit users to enable a failure when the file already exists. This flag is currently unused. Update Makefiles and documentation accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79990 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-23Change raw_fd_ostream to take flags as an optional bitmask Chris Lattner
instead of as two bools. Use this to add a F_Append flag which has the obvious behavior. Other unrelated changes conflated into this patch: 1. REmove EH stuff from llvm-dis and llvm-as, the try blocks are dead. 2. Simplify the filename inference code in llvm-as/llvm-dis, because raw_fd_ostream does the right thing with '-'. 3. Switch machine verifier to use raw_ostream instead of ostream (Which is the thing that needed append in the first place). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79807 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-22llvm-mc: Clean up some handling of symbol/section association to be more correctDaniel Dunbar
(external was really undefined and there wasn't an explicit representation for absolute symbols). - This still needs some cleanup to how the absolute "pseudo" section is dealt with, but I haven't figured out the nicest approach yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79733 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-21llvm-mc: Improve handling of implicit alignment for magic section directivesDaniel Dunbar
(e.g., .objc_message_refs). - Just emit a .align when we see the directive; this isn't exactly what 'as' does but in practice it should be ok, at least for now. See FIXME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79697 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-21llvm-mc: In a .fill directive, still honor .align even if invalid maximum bytesDaniel Dunbar
count is given (this matches 'as'). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79683 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-21llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar
- Together these form the (Mach-O) back end of the assembler. - MCAssembler is the actual assembler backend, which is designed to have a reasonable API. This will eventually grow to support multiple object file implementations, but for now its Mach-O/i386 only. - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API, e.g. converting the various directives into fragments, managing state like the current section, and so on. - llvm-mc will use the new backend via '-filetype=obj', which may eventually be, but is not yet, since I hear that people like assemblers which actually assemble. - The only thing that works at the moment is changing sections. For the time being I have a Python Mach-O dumping tool in test/scripts so this stuff can be easily tested, eventually I expect to replace this with a real LLVM tool. - More doxyments to come. I assume that since this stuff doesn't touch any of the things which are part of 2.6 that it is ok to put this in not so long before the freeze, but if someone objects let me know, I can pull it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79612 91177308-0d34-0410-b5e6-96231b3b80d8
