[PATCH] D115555: [RISCV] Use AdjustInstrPostInstrSelection to insert a FRM dependency for scalar FP instructions with dynamic rounding mode.

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added a comment.

As it stands the implementation is a bit assuming, relying on it only ever being called for floating point instructions (or those that don't have a funct3), but there are other uses, so should also be checking getOperandType is OpTypes::frmarg? Could even ditch the name lookup entirely and just iterate over the use operands, don't know what's better.
