Merge this with the existing hasVALU32BitEncoding check below

tryReplaceDeadSDST(MI);
}

if (!TII->hasVALU32BitEncoding(MI.getOpcode())) {
// If there is no chance we will shrink it and use VCC as sdst to get
// a 32 bit form try to replace dead sdst with NULL.

Adds an extra instruction, is this really better?

Delay alu pass skips implicit def ops (suppose that should be done since it's marked with TODO).

VOP2:
renamable $vgpr13 = V_ADDC_U32_e32 0, killed $vgpr13, implicit-def dead $vcc_lo, implicit killed $vcc_lo, implicit $exec

VOP3:
renamable $vgpr13, dead $sgpr_null = V_ADDC_U32_e64 0, killed $vgpr13, killed $vcc_lo, 0, implicit $exec

In VOP2, vcc is implicit so delay alu will not consider it, but as I understood the correct behaviour would be for delay_alu to be in both?

There are two things going on here:

  1. In general AMDGPUInsertDelayAlu should look at implicit ops, like you said.
  2. But in this specific case of carry out -> carry in, the hardware has a fast forward that means there is no delay, so no s_delay_alu is needed.
