[PATCH] D85203: TableGen/GlobalISel: Allow inst matcher to check multiple opcodes

[Jessica Paquette via Phabricator via llvm-commits]

paquette added a comment.

Could we have more than 2 possible choices for opcodes? Would it make sense to make this take an arbitrary number of alternatives?

Maybe something like

  /// - InsnID - Instruction ID
  /// - NumChoices - Number of possible opcodes
  /// - Opcode1, Opcode2, Opcode3, ... OpcodeNumChoices - Possible opcodes, ordered by preference
  GIM_CheckOpcodeWithAlternatives

I can't think of anything off the top of my head, but it could be useful I suppose.
