Subject: Patch that forces MergeFunctions pass for clang.
X-Git-Tag: android-x86-6.0-r1~129^2~1869
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=33300d91b66a86fc39482dd262fb735ca54d92e1;p=android-x86%2Fexternal-llvm.git

Patch that forces MergeFunctions pass for clang.
It is temporary patch. We need to keep it in trunk, since it makes easer to test it on buildbots on different platforms.
Once we see stable MergeFunctions behaviour with satisfied perfomance, this patch will be removed.
