Two or more PHIs mutually using each other directly or indirectly as incoming value could cause that a PHI WRITE be added before the PHI READ (i.e. it overwrites the current incoming value with the next incoming value before it being read). Fix by ensuring that the PHI WRITE and PHI READ are in the same statement. This should fix the miscompile of SingleSource/Benchmark/Misc/whetstone from the test-suite. llvm-svn: 324934 |

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.
