[LLVMdev] [RFC] Conditional RegClass membership
...e of a hack," - and he suggested instead converting every
instruction that takes an rGPR operand into a multiclass of two
instructions, one predicated on HasV8Ops, and the other on its inverse. This
isn't practical, however: ARMInstrThumb2.td specifies several hundred
individual encodings, InstAliases and match patterns that use rGPR, and all
these would need to be manually duplicated.
Right now, we're trying to come up with a more sensible approach, and
perhaps one that could be useful for other targets as well.
Any suggestions? And are there any other cases where the definition of...
