When adding an llvm.memcpy instruction to AliasSetTracker, it uses the raw source and target pointers which preserve bitcasts. MemAccInst::getPointerOperand() also returns the raw target pointers, but Scop::buildAliasGroups() did not for the source pointer. This lead to mismatches between AliasSetTracker and ScopInfo on which pointer to use. Fixed by also using raw pointers in Scop::buildAliasGroups(). llvm-svn: 285071 |

Polly - Polyhedral optimizations for LLVM ----------------------------------------- http://polly.llvm.org/ Polly uses a mathematical representation, the polyhedral model, to represent and transform loops and other control flow structures. Using an abstract representation it is possible to reason about transformations in a more general way and to use highly optimized linear programming libraries to figure out the optimal loop structure. These transformations can be used to do constant propagation through arrays, remove dead loop iterations, optimize loops for cache locality, optimize arrays, apply advanced automatic parallelization, drive vectorization, or they can be used to do software pipelining.
