[LLVMdev] [PATCH] RegScavenger::scavengeRegister
...o solve. Is that right?
That depends.
The register allocator can spill across register classes, but it calls the functionality "live range splitting" and "register class inflation". Here's how you enable it:
- Define a union register class that contains both CPU64Regs and ACRegs.
- Implement TRI::getLargestLegalSuperClass(), and return the new union register class when asked about CPU64Regs or ACRegs (or their sub-classes).
- Teach TII::copyPhysReg() to handle the cross-class copies.
- Teach TII::storeRegToStackSlot() to constrain the register class to CPU64Regs when a...

[LLVMdev] [PATCH] RegScavenger::scavengeRegister
Hi Jakob,
I believe Hal is trying to enable register scavenger to find two (or more)
registers that can be used as temporaries.
One problem I see with this approach is that, if you use register scavenger
during PEI, you will have to pessimistically set aside two emergency spill
slots before you call scavengeRegister, even if it turns out you only need
one. Having an extra stack slot might not be
