Before we would 'guess' the correct location for the MergeBlock that got introduced when executing a Scop conditionally. This implicitly depends on the situation that at this point during CodeGen there will be nothing between polly.start and polly.exiting. With this commit we explicitly state that we want the block that directly follows polly.exiting. llvm-svn: 306398
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.
