New Revision: 134237

URL: http://llvm.org/viewvc/llvm-project?rev=134237&view=rev
Log:
Disable commit 134216 ("Add 134199 back, but disable the optimization when the second
copy is a kill") to see if it fixes the i386 dragonegg buildbot, which is timing out
because gcc built with dragonegg is going into an infinite loop.
