[PATCH] D125324: AMDGPU/GISel: Factor out AMDGPURegisterBankInfo::buildReadFirstLane

[Ivan Kosarev via Phabricator via llvm-commits]

kosarev added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPURegisterBankInfo.cpp:719
+
+    const TargetRegisterClass *Constrained =
+        constrainGenericRegister(SrcPart, AMDGPU::VGPR_32RegClass, MRI);
----------------
Putting this under `#ifndef NDEBUG` would prevent calling `constrainGenericRegister()` in no-asserts builds.
