r312328 looks most related to me in `svn log -r312327:312359 https://nico@llvm.org/svn/llvm-project/`

Cycled green in https://build.chromium.org/p/chromium.fyi/builders/ClangToTAndroid/builds/1288

First good: 312495
Last bad: 312472

This has:

r312490 | sammccall | 2017-09-04 11:47:00 -0400 (Mon, 04 Sep 2017) | 5 lines

Revert "Re-enable "[MachineCopyPropagation] Extend pass to do COPY source forwarding""

This crashes on boringSSL on PPC (will send reduced testcase)

This reverts commit r312328.


sammccall: Thanks for the revert, and just fyi this crashed on arm too.
