Hi, I've run into an issue with the RegisterBankEmitter on the AMDGPU backend. AMDGPU has a register class: VS_32, which is non-allocatable and contains registers from both defined register banks (SGPRRegBank and VGPRRegBank). The RegisterBankEmitter is adding this class to the CoverageData array for both register classes, because it contains sub-registers of one of the classes explicitly added to the RegisterBank, for example: Added VS_32(explicit (VS_32) VReg_64 class-with-subregs: VReg_64) This is a problem, beca...
