[PATCH] D78092: [GlobalISel][AMDGPU] add legalization for G_FREEZE

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/LegalizerHelper.cpp:4115
+LegalizerHelper::narrowScalarFreeze(MachineInstr &MI, LLT NarrowTy) {
+  Register SrcReg = MI.getOperand(1).getReg();
+  const Register DstReg = MI.getOperand(0).getReg();
----------------
Maybe reduceOperationWidth? We have a reduceLoadStoreWidth shared between fewerElementsVector and narrowScalar
