Hi Jonas, I won’t have time to look at it this week after all. I’ll try to do that next week. If you do not hear back from me by end of next, do not hesitate to ping me!

Cool test :) It seems to work fine now, I don't see any new failures. IIUC, Kristof is also giving it another run.

I was looking at writing a pass after PHI elim to do this, just trying to dump the reaching def MIs but get lots of no live segments issues.

I’d like to nominate Quentin Colombet as LSR code owner. He has handled most of the reviews for me for the past couple years (thanks Quentin), and is willing to take on the responsiblity. Frankly, turning over ownership to Quentin is overdue. -Andy

...t simply transfer the value of the kill flag from the SrcReg to the DstReg. We are extending the live-range of SrcReg. I do not see how you could relate that to the kill flag of DstReg.

AddRegisterOperand calls getVR and yes, I think an IMPLICIT_DEF is being generated.

Hi, Shrink-wrapping capabilities, i.e., better placement of prologue and epilogue sequences, landed in r236507 but are not yet enabled by default. Since r236507 AArch64 is shrink-wrapping ready, meaning we can turn the pass on for this target. I’ve done the same for X86 in r 238293. Now, I need your help to test and benchmark how shrink-wrapping perform on those targets. The goal is to decide

...gets constrained even more. Honestly, I really don't understand this part at all, why even have this type checking? If we have defined a RegClass for that instruction, it should use that regclass or subregclasses (depending on use/def info), correct?

...ectly allowed for the MOV16Copy instruction. I really just want to know if there is any way currently to get the TD defined register class for an operand for a machine instruction. There must be a way since LLVM produces valid registers for the operands.
