Here is the patch to fix up Darwin,
I guess it’s both Darwin-local and reasonably obvious now, but OK?

[PATCH] rs6000,Darwin: Remove uses of LR in restore_world.
Darwin had an additional use of LR in the restore_world machinery. This patch
removes it from the pattern in altivec.md and the relevant predicate. Many
thanks to Segher for detailed pointers to the solutions.

* config/rs6000/altivec.md (*restore_world): Remove LR use.
* config/rs6000/predicates.md (restore_world_operation): Adjust count
op count, remove one USE.
