◆ readlaneVGPRToSGPR()
| Register SIInstrInfo::readlaneVGPRToSGPR | ( | Register | SrcReg, |
| MachineInstr & | UseMI, | ||
| MachineRegisterInfo & | MRI | ||
| ) | const |
Copy a value from a VGPR (SrcReg) to SGPR.
This function can only be used when it is know that the value in SrcReg is same across all threads in the wave.
- Returns
- The SGPR register that
SrcRegwas copied to.
