[PATCH] D140530: [RISCV] Add integer scalar instructions to isAssociativeAndCommutative

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.cpp:1354
+  return RISCV::hasEqualFRM(Inst, Sibling) ||
+         (InstFrmOpIdx < 0 && SiblingFrmOpIdx < 0);
 }
----------------
swap the order of these conditions. There's no reason to call hasEqualFRM if we already know both indices are negative.
