[Bug tree-optimization/117510] Inner loop with static trip count breaks vectorization of outer loop

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117510 --- Comment #4 from Freddie Witherden --- (In reply to Richard Biener from comment #3) > Fixed for GCC 15. Thanks! If I have cases which, when m is a compile time constant, vectorize for m small but not m large is that likely to be a separate i
