[PATCH] D104149: [MCA] Adding the CustomBehaviour class to llvm-mca

[Patrick Holland via Phabricator via llvm-commits]

holland11 updated this revision to Diff 352014.
holland11 added a comment.

Made some changes suggested by Andrea.

- Removed the X86CustomBehaviour class
- Modified the MCAOperands to only be stored for specific instructions (and only specific operands from those instructions)
- Added the InstrPostProcess class for modifying the mca::Instruction objects after they are created, but before they are added to the LoweredSequence
- Modified the CustomBehaviour section of the docs
- Changed some assert(RegID) lines into if (!RegID) lines that either exit the current function or continue the current loop (this will make it so that InstrPostProcess can remove instruction Defs by setting that Def's RegisterID to 0)
- And some other small changes.
