2010-11-06fix another fixme, replacing a string with a semantic pointer.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118325 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-06disolve a hack, having CodeGenInstAlias decode the alias in the .tdChris Lattner
file instead of the asmmatcher. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118324 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04In the calling convention logic, ValVT is always a legal type,Duncan Sands
and as such can be represented by an MVT - the more complicated EVT is not needed. Use MVT for ValVT everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118245 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04partition operand processing between aliases and instructions.Chris Lattner
Right now the code is partitioned but the behavior is the same. This should be improved in the near future. This removes some uses of TheOperandList. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118232 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04pull name slicing out of BuildInstructionOperandReference soChris Lattner
it doesn't do any lexical stuff anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118230 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-04replace SrcOpNum with SrcOpName, eliminating a numering dependencyChris Lattner
on the incoming operand list. This also makes the code simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118225 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04strength reduce some code, resolving a fixme.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118219 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04take a big step to making aliases more general and less of a hack:Chris Lattner
now matchables contain an explicit list of how to populate each operand in the result instruction instead of having them somehow magically be correlated to the input inst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118217 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Support generating an MC'ized CodeEmitter directly. Maintain a reference to theJim Grosbach
Fixups list for the instruction so the operand encoders can add to it as needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118206 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03rename Operand -> AsmOperand for clarity.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118190 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Inside the calling convention logic LocVT is always a simpleDuncan Sands
value type, so there is no point in passing it around using an EVT. Use the simpler MVT everywhere. Rather than trying to propagate this information maximally in all the code that using the calling convention stuff, I chose to do a mainly low impact change instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118167 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Break ARM addrmode4 (load/store multiple base address) into its constituentJim Grosbach
parts. Represent the operation mode as an optional operand instead. rdar://8614429 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02Completely reject instructions that have an operand in theirChris Lattner
ins/outs list that isn't specified by their asmstring. Previously the asmmatcher would just force a 0 register into it, which clearly isn't right. Mark a bunch of ARM instructions that use this as isCodeGenOnly. Some of them are clearly pseudo instructions (like t2TBB) others use a weird hasExtraSrcRegAllocReq thing that will either need to be removed or the asmmatcher will need to be taught about it (someday). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118119 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02make MatchableInfo::Validate reject instructions (like LDR_PRE in ARM)Chris Lattner
that have complicated tying going on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118112 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02rewrite EmitConvertToMCInst to iterate over the MCInst operands,Chris Lattner
filling them in one at a time. Previously this iterated over the asmoperands, which left the problem of "holes". The new approach simplifies things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118104 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02merge two large parallel loops in EmitConvertToMCInst, no changeChris Lattner
in the generated .inc files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118083 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02a bunch of random cleanup, move a helper to CGT where it belongs.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118031 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02Revert r114340 (improvements in Darwin function prologue/epilogue), as it brokeJim Grosbach
assumptions about stack layout. Specifically, LR must be saved next to FP. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118026 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02add and update comments.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118025 91177308-0d34-0410-b5e6-96231b3b80d8
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
2010-11-02rename operands -> asmoperands to be more descriptive.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117993 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
2010-11-01give MatchableInfo::Operand a constructorChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117968 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
2010-11-01avoid needless throw/catch/rethrow, stringref'ize some simple stuff.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117892 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01eliminate the old InstFormatName which is always "AsmString",Chris Lattner
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, $lane in ARM is an issue that needs to be resolved beforeChris Lattner
this can start rejecting instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117885 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01reject instructions that contain a \n in their asmstring. MarkChris Lattner
various X86 and ARM instructions that are bitten by this as isCodeGenOnly, as they are. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117884 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-31fix a crash on:Chris Lattner
let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 { we now get: X86InstrCompiler.td:653:52: error: Expected class, def, defm, multiclass or let definition let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 { ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117863 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
2010-10-31reapply r117858 with apparent editor malfunction fixed (somehow I Chris Lattner
got a dulicated line). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117860 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-31revert r117858 while I check out a failure I missed.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117859 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 a fixme in stringmatcher, having it generate nice looking code if theChris Lattner
'tomatch' code contains \n's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117843 91177308-0d34-0410-b5e6-96231b3b80d8
