Chandler Carruth	49589f0d0e	Convert the uses of '|&' to use '2>&1 |' instead, which works on old ... versions of Bash. In addition, I can back out the change to the lit built-in shell test runner to support this. This should fix the majority of fallout on Darwin, but I suspect there will be a few straggling issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159544 91177308-0d34-0410-b5e6-96231b3b80d8	2012-07-02 18:37:59 +00:00
Dan Gohman	1fc18d71de	Fix BasicAA's recursion detection so that it doesn't pessimize ... queries in the case of a DAG, where a query reaches a node visited earlier, but it's not on a cycle. This avoids MayAlias results in cases where BasicAA is expected to return MustAlias or PartialAlias in order to protect TBAA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132609 91177308-0d34-0410-b5e6-96231b3b80d8	2011-06-04 00:31:50 +00:00
