Dan Gohman a8c144d534 Revert the rule that considers comparisons between two pointers in the ... same object to be a non-capture; Duncan pointed out a way that such a comparison could be a capture. Make the rule that considers a comparison against null more specific, and only consider noalias return values compared against null. This still supports test/Transforms/GVN/nonescaping-malloc.ll, and is not susceptible to the problem Duncan pointed out with noalias arguments. llvm-svn: 89468		2009-11-20 17:50:21 +00:00
