[PATCH] D126807: [PowerPC] Fix LQ-STQ instructions to use correct offset and base

[Kai Luo via Phabricator via llvm-commits]

lkail added a comment.

I think the root cause here is `lq/stq` is leaking x-form. There are `LQX_PSEUDO` and `STQX_PSEUDO` defined to assist accessing big offset inside the stack, but there are expanded pre-RA. I think we should expand them in `PPCAtomicExpandPass` and make `lq/stq`'s x-form mapping to `LQX_PSEUDO/STQX_PSEUDO`.
