From bc9e523421b77c4086ddd58162733db13be708e2 Mon Sep 17 00:00:00 2001 From: Duncan Sands Date: Fri, 1 Jul 2011 12:01:00 +0000 Subject: [PATCH] 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. llvm-svn: 134237 --- llvm/lib/CodeGen/RegisterCoalescer.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/llvm/lib/CodeGen/RegisterCoalescer.cpp b/llvm/lib/CodeGen/RegisterCoalescer.cpp index 3b982d67e7b0..d5025b9e636f 100644 --- a/llvm/lib/CodeGen/RegisterCoalescer.cpp +++ b/llvm/lib/CodeGen/RegisterCoalescer.cpp @@ -1203,6 +1203,7 @@ static bool RegistersDefinedFromSameValue(LiveIntervals &li, VNInfo *VNI, LiveRange *LR, SmallVector &DupCopies) { + return false; // To see if this fixes the i386 dragonegg buildbot miscompile. // FIXME: This is very conservative.
