[PATCH] D150415: [RISCV] Add a pass to merge moving parameter registers instructions for Zcmp

[Craig Topper via Phabricator via llvm-commits]

craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVMoveOptimizer.cpp:9
+//
+// This file contains a pass that performs move related peephole
+// optimizations. This pass should be run after register allocation.
----------------
This description should mention Zcmp


================
Comment at: llvm/lib/Target/RISCV/RISCVMoveOptimizer.cpp:223
+
+  TII = static_cast<const RISCVInstrInfo *>(Subtarget->getInstrInfo());
+  TRI = Subtarget->getRegisterInfo();
----------------
This static_cast isn't necessary. `RISCVSubtarget` has an implementation of getInstrInfo that returns `RISCVInstrInfo *`
