--- Comment #27 from Andrew Udvare <audv...@gmail.com> --- The UBSAN/ASAN output is probably not related. -fno-tree-vectorize does not resolve the issue with -march=native (or x86-64-v4) which is suprising. For the last test these were the flags: CXXFLAGS="-O2 -ggdb -march=native -mtune=native -pipe -fno-tree-vectorize -fsanitize=undefined" LDFLAGS="-Wl,-O1 -Wl,--as-needed -fsanitize=undefined" Expanded native: CXXFLAGS="-O2 -ggdb -march=rocketlake -mabm --param=l1-cache-line-size=64 --param=l1-cache-size=48 --param=l2-cache-size=16384 -pipe -fno-tree-vectorize -fsanitize=undefined" LDFLAGS="-Wl,-O1 -Wl,--as-needed -fsanitize=undefined" rocketlake can be replaced with x86-64-v4 and the results will be the same. -- You are receiving this mail because: You are watching all bug changes.
