[llvm-commits] [RFC/Patch 1/2 ] ppc64-elf-linux-abi Add instruction tokens for tblgen

[Will Schmidt]

subj: ppc64-elf-linux-abi Add instruction tokens for tblgen.

As part of getting AsmParser working for PPC64-Elf-Linux ABI,  This is a
first-pass that resolves some of the errors generated when trying to do
"llvm-tblgen -gen-asm-matcher" operations against PPC.td and friends.

This change should not affect the current behavior of the build, and
should be safe to commit this patch if it looks OK as a first pass, and
if someone would be so kind to do so. 

- add tokens to PPCInstrInfo.td and PPCInstr64Bit.td to resolve
"Instruction 'foo' has no tokens" errors.  At this time, the added
tokens are "#comment" style rather than the eventual "mnemonic ", thus
more activity will follow once the rest of the asmparser bits get
straightened out.
- Add operands for a few of those tokens to resolve "Instruction 'foo'
has operand 'bar' that doesn't appear in asm string" errors.
- add 'isCodeGenOnly = 1' indicator where indicated to resolve
"matchable with operand modifier '${cond:cc}' not supported by asm
matcher. Mark isCodeGenOnly!" errors.

The makefile and other asmparser bits that would enable the tblgen
activity will be shared under a [RFC] patch as a reply to this one.

Thanks, 
-Will
