[PATCH] D79864: [PowerPC] Add new linker optimization for PowerPC

[Stefan Pintilie via Phabricator via llvm-commits]

stefanp updated this revision to Diff 267685.
stefanp added a comment.

Moved the linker opt detection into the pre-emit peephole.
This should solve the problem where instructions between the `PLD` and the second load/store make the optimization unsafe.
