[PATCH] D33243: [Atomics][LoopIdiom] Recognize unordered atomic memcpy

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

Patch was reverted in https://reviews.llvm.org/rL304315 because of undefined reference to `RTLIB::getMEMCPY_ELEMENT_ATOMIC` in polly (http://lab.llvm.org:8011/builders/polly-arm-linux/builds/5582) and mingw builds. Not sure whether the other builds link RTLIB. clang seemed to pass fine (http://lab.llvm.org:8011/builders/clang-x86_64-debian-fast/builds/4373)
