Subject: Disable the protection from escaped allocas in an attempt to find violating passes... 
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a26cadc58d32a739ccf99423922bfc542c1026b1;p=oota-llvm.git

Disable the protection from escaped allocas in an attempt to find violating passes. This may break the buildbots. I plan to revert it in a few hours.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164024 91177308-0d34-0410-b5e6-96231b3b80d8
