[PATCH] D95708: [GlobalISel] Make sure G_ASSERT_ZEXT's src ends up with the same rc as dst

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/InstructionSelect.cpp:146
+        const TargetRegisterClass *DstRC = MRI.getRegClassOrNull(DstReg);
+        if (DstRC && !MRI.getRegClassOrNull(SrcReg))
+          MRI.setRegClass(SrcReg, DstRC);
----------------
!MRI.getRegClassOrNull(SrcReg) should be redundant since this would have been invalid if it weren't the same class anyway
