From 7edcd376d38df602f9c4618108063f2b2933edda Mon Sep 17 00:00:00 2001 From: Sean Fertile Date: Fri, 15 Dec 2017 19:29:12 +0000 Subject: [Memcpy Loop Lowering] Insert loop BB inbetween the split BB. The original memcpy expansion inserted the loop basic block inbetween the 2 new basic blocks created by splitting the original block the memcpy call was in. This commit makes the new memcpy expansion do the same to keep the layout of the IR matching between the old and new implementations.
