Tyler Nowicki 49268c1eff Improve vectorization diagnostic messages and extend vectorize(enable) pragma. ... This patch changes the analysis diagnostics produced when loops with floating-point recurrences or memory operations are identified. The new messages say "cannot prove it is safe to reorder * operations; allow reordering by specifying #pragma clang loop vectorize(enable)". Depending on the type of diagnostic the message will include additional options such as ffast-math or __restrict__. This patch also allows the vectorize(enable) pragma to override the low pointer memory check threshold. When the hint is given a higher threshold is used. See the clang patch for the options produced for each diagnostic. llvm-svn: 246187		2015-08-27 18:56:49 +00:00
