Chandler Carruth	5da53436d5	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. llvm-svn: 159544	2012-07-02 18:37:59 +00:00
Dan Gohman	fb02cec44e	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. llvm-svn: 132609	2011-06-04 00:31:50 +00:00
