Chris Lattner 710429645a Fix PR2496, a really nasty bug which involved sinking volatile loads ... into phis. This is actually the same bug as PR2262 / 2008-04-29-VolatileLoadDontMerge.ll, but I missed checking the first predecessor for multiple successors. Testcase here: InstCombine/2008-07-08-VolatileLoadMerge.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53240 91177308-0d34-0410-b5e6-96231b3b80d8		2008-07-08 17:18:32 +00:00
