Only > use-after-return requires different flags for GCC and clang? Most of the options are compatible, for example these (a subset): `-fsanitize=undefined -fno-sanitize-recover=all -fsanitize=float-divide-by-zero -fsanitize=float-cast-overflow -fno-sanitize=null -fno-sanitize=alignment` But compile-time `use-after-return` setting is not. There are only 8 gcc `--param` `asan-*` keywords, I do not know why. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/19843#discussion_r1651116823
