...or review.
The first patch is mostly a no functional change. It introduces the new
scheduling predicate class in tablegen, and it teaches the
InstructionInfoEmitter and the SubtargetEmitter how to expand
MCSchedPredicate
definitions.
The first patch is up for review here: https:://reviews.llvm.org/D46695.
The second patch would teach the SubtargetEmitter how to generate method
resolveVariantSchedClass().
The last patch of the sequence will teach llvm-mca how to use method
`resolveVariantSchedClass()` to resolve variant classes. llvm-mca will
generate an error if the variant scheduling class canno...
