instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104231 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13reapply r103668 with a fix. Never make "minor syntax changes"Chris Lattner
after testing before committing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103681 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12revert r103668 for now, it is apparently breaking things.Chris Lattner

2010-05-12moffset forms of moves are x86-32 only, make the parserChris Lattner
lower them to the correct x86-64 instructions since we don't have a clean way to handle this in td files yet. rdar://7947184 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103668 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-12MC/X86: Extend suffix matching hack to match 'q' suffix.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103535 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-04MC/X86: Chris pointed that 'as' isn't consistent in accepting the long form ofDaniel Dunbar
instructions which have no direct register usage. Darwin 'as' accepts: add $0, (%rax) but rejects mov $0, (%rax) for example. Given that, only accept suffix matches which match exactly one form. We still need to emit nice diagnostics for failures... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103015 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-04MC/X86: Add "support" for matching ATT style mnemonic prefixes.Daniel Dunbar
- The idea is that when a match fails, we just try to match each of +'b', +'w', +'l'. If exactly one matches, we assume this is a mnemonic prefix and accept it. If all match, we assume it is width generic, and take the 'l' form. - This would be a horrible hack, if it weren't so simple. Therefore it is an elegant solution! Chris gets the credit for this particular elegant solution. :) - Next step to making this more robust is to have the X86 matcher generate the mnemonic prefix information. Ideally we would also compute up-front exactly which mnemonic to attempt to match, but this may require more custom code in the matcher than is really worth it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103012 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-18MC/X86/AsmMatcher: Use the new instruction cleanup routine to implement aDaniel Dunbar
temporary workaround for matching inc/dec on x86_64 to the correct instruction. - This hack will eventually be replaced with a robust mechanism for handling matching instructions based on the available target features. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98858 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-03Added support for X86 instruction prefixes so llvm-mc can assemble them. TheKevin Enderby
Lock prefix, Repeat string operation prefixes and the Segment override prefixes. Also added versions of the move string and store string instructions without the repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is happy building the disassembler files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95252 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-02AsmParser/X86: Add temporary hack to allow parsing "sal". Eventually we needDaniel Dunbar
some mechanism for specifying alternative syntaxes, but I'm not sure what form that should take yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95158 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-02MCAsmParser/X86: Represent absolute memory operands as CodeGen does, with scaleDaniel Dunbar
== 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-30MC/X86 AsmParser: Handle absolute memory operands correctly. We were doingDaniel Dunbar
something totally broken and parsing them as immediates, but the .td file also had the wrong match class so things sortof worked. Except, that is, that we would parse movl $0, %eax as movl 0, %eax Feel free to guess how well that worked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94869 91177308-0d34-0410-b5e6-96231b3b80d8

register, and use to cleanup a FIXME in X86AsmParser.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94859 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-24fix a parsing problem on instructions like:Chris Lattner
movw $8, (_cost_table_-L97$pb)+66(%eax) After the parens, we could still have a binop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94345 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23Added the skeleton for the implementation of the X86Sean Callanan
target-specific AsmLexer, and added the appropriate registration calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94275 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23Modified the register matcher function in AsmMatcher toSean Callanan
be static. Also made it possible for clients to get it and no other functions from ...GenAsmMatcher.inc by defining REGISTERS_ONLY before including GenAsmMatcher.inc. This sets the stage for target-specific lexers that can identify registers and return AsmToken::Register as appropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94266 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19Promoted the getTok() method to MCAsmParser so thatSean Callanan
the two token accessor functions are declared consistently. Modified the clients of MCAsmParser to reflect this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93916 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Propagated the parser-side Lex function's declaration toSean Callanan
MCAsmParser, and changed the target-specific AsmParsers to use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93900 91177308-0d34-0410-b5e6-96231b3b80d8

datastructure when parsing a mem operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93521 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-14Split the TargetAsmParser "ParseInstruction" interface in half:Chris Lattner
the new ParseInstruction method just parses and returns a list of target operands. A new MatchInstruction interface is used to turn the operand list into an MCInst. This requires new/deleting all the operands, but it also gives targets the ability to use polymorphic operands if they want to. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93469 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-14prune #includes in TargetAsmParser.hChris Lattner
Pass in SMLoc of instr opcode into ParseInstruction. Make AsmToken be a class, not a struct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93457 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-16Fix incorrect assert that should be a user error for code like 'mov $0, %%eax'.Kevin Enderby
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82054 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

disabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81122 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
2009-08-31llvm-mc: Switch MCInst to storing an MCExpr* instead of an MCValue.Daniel Dunbar
Also, use MCInst::print instead of custom code in MCAsmPrinter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80575 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-14Update llvm-mc / MCAsmStreamer to print the instruction using the actual targetDaniel Dunbar
specific printer (this only works on x86, for now). - This makes it possible to do some correctness checking of the parsing and matching, since we can compare the results of 'as' on the original input, to those of 'as' on the output from llvm-mc. - In theory, we could now have an easy ATT -> Intel syntax converter. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78986 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-11llvm-mc/X86: Parse '*' correctly (in the way the matcher expects).Daniel Dunbar

2009-08-10llvm-mc/AsmParser: Allow .td users to redefine the names of the methods to callDaniel Dunbar
on target specific operands for testing class membership and converting to MCInst operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78597 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-09llvm-mc/AsmParser: Implement user defined super classes.Daniel Dunbar
- We can now discriminate SUB32ri8 from SUB32ri, for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78530 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08llvm-mc/AsmMatcher: Switch token matching to use the new string matcher.Daniel Dunbar
Also, redefined MatchRegisterName to just return the register value or a sentinel, to simplify the generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78504 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-08llvm-mc/AsmMatcher: Improve match code.Daniel Dunbar
- This doesn't actually improve the algorithm (its still linear), but the generated (match) code is now fairly compact and table driven. Still need a generic string matcher. - The table still needs to be compressed, this is quite simple to do and should shrink it to under 16k. - This also simplifies and restructures the code to make the match classes more explicit, in anticipation of resolving ambiguities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78461 91177308-0d34-0410-b5e6-96231b3b80d8
