[PATCH] D99723: [ARM] Transforming memcpy to Tail predicated Loop

[Malhar via Phabricator via llvm-commits]

malharJ updated this revision to Diff 342948.
malharJ added a comment.

Added an update to ensure that the block containin memcpy pseudo is always
split using splitAt().

An example case where this is important is when updating
phi instructions in successive blocks, which is taken care of by splitAt().
A test has been added for the same.
