[PATCH] D132233: [CGP][ARM] Dont align memcpy args when optimization for size

[Dave Green via Phabricator via llvm-commits]

dmgreen updated this revision to Diff 455277.
dmgreen added a comment.

I've updated the test with all the output - and just shown the diffs here. With that test, if the array is no longer aligned then a series of load/stores will be needed, an LDM will have too-high alignment requirements.
