* llvm/test/Transforms/LoopRotate/PhiRename-1.ll: FileCheck-ize. It fixes PR13301.NAKAMURA Takumi2012-07-171-2/+3
| | | | | | It began choking since Chandler's r159547, possibly due to improper expression on grep from TclParser to ShParser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160367 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow for customized graph edge pruning in PostOrderIterator.hJakob Stoklund Olesen2012-07-172-38/+73
| | | | | | | | | | | | | | | | Make it possible to prune individual graph edges from a post-order traversal by specializing the po_iterator_storage template. Previously, it was only possible to prune full graph nodes. Edge pruning makes it possible to remove loop back-edges, for example. Also replace the existing DFSetTraits customization hook with a po_iterator_storage method for observing the post-order. DFSetTraits was only used by LoopIterator.h which now provides a po_iterator_storage specialization. Thanks to Sean and Chandler for reviewing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160366 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | It turns out that ASan relied on the at-the-end block insertion order to (purely by happenstance) disable some LLVM optimizations, which in turn start firing when the ordering is made more "normal". These optimizations in turn merge many of the instrumentation reporting calls which breaks the return address based error reporting in ASan. We're looking at several different options for fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160256 91177308-0d34-0410-b5e6-96231b3b80d8
