--- Comment #3 from Hongtao.liu <crazylht at gmail dot com> --- >From pr108883, maybe we shouldnot restrict _Float16 under TARGET_SSE2. Jakub Jelinek 2023-02-22 12:21:24 UTC Created attachment 54506 [details] gcc13-pr108883.patch Untested fix on the compiler side of emit_support_tinfos. That said, these fundamental types whose presence/absence depends on ISA flags are quite problematic IMHO, as they are incompatible with the target attribute/pragmas. Whether they are available or not available depends on whether in this case SSE2 is enabled during compiler initialization (aka after parsing command line options) and then they are available or unavailable to everything else based on that.
