DEBUG_TYPE

#define DEBUG_TYPE   "amdgpu-regbankselect"

Assign register banks to all register operands of G_ instructions using machine uniformity analysis.

Sgpr - uniform values and some lane masks Vgpr - divergent, non S1, values Vcc - divergent S1 values(lane masks) However in some cases G_ instructions with this register bank assignment can't be inst-selected. This is solved in AMDGPURegBankLegalize.
