The implementation of computeArrayUnused did not consider writes without reads before, except for the first write in the SCoP. This caused it to 'forget' writes directly following another write. This patch re-adds the entire reaching defintion of a write that has not been covered before by a read. This fixes Polybench 4.2 2mm where only one of the matrix-multiplication was detected. llvm-svn: 311403 |

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.
