2010-11-02refactor/cleanup MatchableInfo by eliminating the Tokens array,Chris Lattner
merging it into a Token field in Operand, and moving the first token to an explicit mnemonic field. These were parallel arrays before (except for the mnemonic) which kept confusing me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118024 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-01fix computation of ambiguous instructions to not ignore the mnemonic.Chris Lattner
FWIW, X86 has 254 ambiguous instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117979 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-01Implement enough of the missing instalias support to getChris Lattner
aliases installed and working. They now work when the matched pattern and the result instruction have exactly the same operand list. This is now enough for us to define proper aliases for movzx and movsx, implementing rdar://8017633 and PR7459. Note that we do not accept instructions like: movzx 0(%rsp), %rsi GAS accepts this instruction, but it doesn't make any sense because we don't know the size of the memory operand. It could be 8/16/32 bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117901 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01rename InstructionInfo -> MatchableInfo since it nowChris Lattner
represents InstAliases as well. Rename isAssemblerInstruction -> Validate since that is what it does (modulo the ARM $lane hack). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117899 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01refactor initialization of InstructionInfo to be sharable betweenChris Lattner
instructions and InstAliases. Start creating InstructionInfo's for Aliases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117898 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01make the asm matcher emitter reject instructions that have commentsChris Lattner
in their asmstring. Fix the two x86 "NOREX" instructions that have them. If these comments are important, the instlowering stuff can print them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117897 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01refactor InstructionInfo to not have a pointer to CodeGenInstructionChris Lattner
member, and make isAssemblerInstruction() a method (pushing some code around inside it). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117895 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01define a new CodeGenInstAlias. It has an asmstring and operand list for now,Chris Lattner
todo: the result field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117894 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01factor the operand list (and related fields/operations) out of Chris Lattner
CodeGenInstruction into its own helper class. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117893 91177308-0d34-0410-b5e6-96231b3b80d8

simplify CodeGenInstruction. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117891 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01all predicates on an MnemonicAlias must be AssemblerPredicates.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117890 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01change the singleton register handling code to be based on Record*'sChris Lattner
instead of strings, simplifying it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117889 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01Give AsmMatcherInfo a CodeGenTarget, which simplifies a bunch ofChris Lattner
argument passing. Consolidate all SingletonRegister detection and handling into a new InstructionInfo::getSingletonRegisterForToken method instead of having it scattered about. No change in generated .inc files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117888 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01move FlattenVariants out of AsmMatcherEmitter into a sharedChris Lattner
CodeGenInstruction::FlattenAsmStringVariants method. Use it to simplify the code in AsmWriterInst, which now no longer needs to worry about variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117886 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01add a FIXME, $lane in ARM is an issue that needs to be resolved beforeChris Lattner
this can start rejecting instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117885 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01reject instructions that contain a \n in their asmstring. MarkChris Lattner
various X86 and ARM instructions that are bitten by this as isCodeGenOnly, as they are. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117884 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-31fix the !eq operator in tblgen to return a bit instead of an int.Chris Lattner
Use this to make the X86 and ARM targets set isCodeGenOnly=1 automatically for their instructions that have Format=Pseudo, resolving a hack in tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117862 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-31two changes: make the asmmatcher generator ignore ARM pseudos properly,Chris Lattner
and make it a hard error for instructions to not have an asm string. These instructions should be marked isCodeGenOnly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117861 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-31the asm matcher can't handle operands with modifiers (like ${foo:bar}).Chris Lattner
Instead of silently ignoring these instructions, emit a hard error and force the target author to either refactor the target or mark the instruction 'isCodeGenOnly'. Mark a few instructions in ARM and MBlaze as isCodeGenOnly the are doing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117858 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-30have GetAliasRequiredFeatures get its features fromChris Lattner
AsmMatcherInfo so we don't have two places that know the feature -> enum mapping. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117845 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-30simplify code that creates SubtargetFeatureInfo, ensuring that features Chris Lattner
that are only used by MnemonicAliases will be found. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117844 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-30fix typos and some serious bugs in feature handling (but not forChris Lattner

2010-10-30Resolve a terrible hack in tblgen: instead of hardcodingChris Lattner
"In32BitMode" and "In64BitMode" into tblgen, allow any predicate that inherits from AssemblerPredicate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117831 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-30Implement (and document!) support for MnemonicAlias's to have Requires Chris Lattner
directives, allowing things like this: def : MnemonicAlias<"pop", "popl">, Requires<[In32BitMode]>; def : MnemonicAlias<"pop", "popq">, Requires<[In64BitMode]>; Move the rest of the X86 MnemonicAliases over to the .td file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117830 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-30diagnose targets that define two alises with the same 'from' mnemonicChris Lattner
