* Teach X86 asm parser that VMOVAPSrr and other VEX-encoded register to ↵Craig Topper2013-10-07
| | | | | | | | | | register moves should be switched from using the MRMSrcReg form to the MRMDestReg form if the source register is a 64-bit extended register and the destination register is not. This allows the instruction to be encoded using the 2-byte VEX form instead of the 3-byte VEX form. The GNU assembler has similar behavior and instruction selection already does this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192088 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an instruction deprecation feature to TableGen.Joey Gouly2013-09-12
| | | | | | | | | | | | | | | | | | | | | | | | The 'Deprecated' class allows you to specify a SubtargetFeature that the instruction is deprecated on. The 'ComplexDeprecationPredicate' class allows you to define a custom predicate that is called to check for deprecation. For example: ComplexDeprecationPredicate<"MCR"> would mean you would have to define the following function: bool getMCRDeprecationInfo(MCInst &MI, MCSubtargetInfo &STI, std::string &Info) Which returns 'false' for not deprecated, and 'true' for deprecated and store the warning message in 'Info'. The MCTargetAsmParser constructor was chaned to take an extra argument of the MCInstrInfo class, so out-of-tree targets will need to be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190598 91177308-0d34-0410-b5e6-96231b3b80d8

* [ms-inline asm] Fix a crasher when we fail on a direct match.Chad Rosier2013-05-10
| | | | | | | | | | | | | | | | | | | The issue was that the MatchingInlineAsm and VariantID args to the MatchInstructionImpl function weren't being set properly. Specifically, when parsing intel syntax, the parser thought it was parsing inline assembly in the at&t dialect; that will never be the case. The crash was caused when the emitter tried to emit the instruction, but the operands weren't set. When parsing inline assembly we only set the opcode, not the operands, which is used to lookup the instruction descriptor. rdar://13854391 and PR15945 Also, this commit reverts r176036. Now that we're correctly parsing the intel syntax the pushad/popad don't match properly. I've reimplemented that fix using a MnemonicAlias. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181620 91177308-0d34-0410-b5e6-96231b3b80d8
