If we don't know anything about the alignment of a pointer, Align(1) is still correct: all pointers are at least 1-byte aligned. Included in this patch is a bugfix for an issue discovered during this cleanup: pointers with "dereferenceable" attributes/metadata were assumed to be aligned according to the type of the pointer. This wasn't intentional, as far as I can tell, so Loads.cpp was fixed to stop making this assumption. Frontends may need to be updated. I updated clang's handling of C++ references, and added a release note for this. Differential Revision: https://reviews.llvm.org/D80072 |

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.
