Is the code you have pasted with the PHIs feed to the register coalescer? I am trying to understand the setting to help debugging the problem. Also, what does -debug-only=regalloc tell you?

Hi, I am working on a simple copy propagation pass for the R600 backend that propagates immediates rather than registers. For example, I want to transform: ... %vreg1 = V_MOV_B32 1 %vreg2 = V_ADD_I32 %vreg1, %vreg0 ... into: %vreg1 = V_MOV_B32 1 ; <- Only delete this if it is dead %vreg2 = V_ADD_I32 1, %vreg0 For best results, I am trying to run this pass after the TwoAddressInstruction
