[Bug tree-optimization/115120] Bad interaction between ivcanon and early break vectorization

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115120 --- Comment #4 from Tamar Christina --- You asked why this doesn't happen with a normal vector loop Richi. For a normal loop when IVcannon adds the downward counting loop there are two main differences. 1. for a single exit loop, the downward

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115533 --- Comment #20 from Alexander Monakov --- Sam, can you provide more context? It seems there is no downstream bugreport? How does the alleged miscompilation manifest? Note that effects of interplay of fp-contract=fast and vectorization can be p

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115533 --- Comment #22 from Alexander Monakov --- Similar to the RawTherapee issue, SLP opportunities are created by predcom, so either -fno-predictive-commoning or -fno-tree-slp-vectorize avoids numerical runaway on the small testcase.
