Why can't you just mark the frame address callee save? Why isn't it
getting saved automatically for you?
Because R31 is not used as a callee saved register when
llvm::NoFramePointerElim is set to 1. The algorithm

NoFramePointerElim doesn't change the ABI, only the codegen model.
Yes it doesn't change the ABI, but R31's offset in Linux/ELF is in the
callee saved area. In Macho it is

Ok, so it's not related to NoFramePointerElim? If that's the case,
you should just have Macho and ELF return different sets of callee

No, that's not the issue.
Let me rephrase why I need this patch :)
In PowerPC, whether it's on ELF ABI or MachO, R31 is a

Hi Chris,

Ahhh, ok. I think I understand now what is going on. Thank you for
the very clear explanation.
In this case, it seems like a clearly good thing to just call
CreateFixedObject unconditionally early on (e.g.) when lowering the
arguments.
Unconditionally?
Here's the final patch with the modifications you suggested. Thx a lot
for your reviewing Chris.
If everything's OK I'm checking this in soon.
Cheers,
Nicolas

there's no objection.
Chris: Just a question. I noticed on cvsweb that you wrote the lines:
