Macro Definition Documentation

DEBUG_TYPE

#define DEBUG_TYPE   "amdgpu-regbanklegalize"

Lower G_ instructions that can't be inst-selected with register bank assignment from AMDGPURegBankSelect based on machine uniformity info.

Given types on all operands, some register bank assignments require lowering while others do not. Note: cases where all register bank assignments would require lowering are lowered in legalizer. For example vgpr S64 G_AND requires lowering to S32 while sgpr S64 does not. Eliminate sgpr S1 by lowering to sgpr S32.
