Michael Gottesman	3ed7576a3b	[objc-arc] Track if we encountered an additive overflow while computing {TopDown,BottomUp}PathCounts and do nothing if it occurred. ... I fixed the aforementioned problems that came up on some of the linux boxes. Major thanks to Nick Lewycky for his help debugging! rdar://14590914 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188122 91177308-0d34-0410-b5e6-96231b3b80d8	2013-08-09 23:22:27 +00:00
Michael Gottesman	35b6edfbea	Revert "[objc-arc] Track if we encountered an additive overflow while computing {TopDown,BottomUp}PathCounts and do nothing if it occured." ... This reverts commit r187941. The commit was passing on my os x box, but it is failing on some non-osx platforms. I do not have time to look into it now, so I am reverting and will recommit after I figure this out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187946 91177308-0d34-0410-b5e6-96231b3b80d8	2013-08-08 00:41:18 +00:00
