[PATCH] D152512: [RISCV] Move getRVVMCOpcode to RISCVInstrInfo.h

[Wang Pengcheng via Phabricator via llvm-commits]

pcwang-thead added a comment.

One concern: is it possible to be false positive for these usages (though I haven't found any failed test)? When mapping pseudos to MC opcode, we may lost some information like `MASK`, `TIED`, `TU/TA`, etc.



================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.cpp:2145
-#define CASE_VFMA_OPCODE_COMMON(OP, TYPE, LMUL)                                \
-  RISCV::PseudoV##OP##_##TYPE##_##LMUL
-
----------------
For example, we didn't catch `_MASK` here.
