Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC|jakub at redhat dot com | --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think that is the preexisting C issue I've talked about in https://gcc.gnu.org/pipermail/gcc-patches/2022-October/603265.html typedef float __attribute__((vector_size (16))) float32x4_t; float32x4_t foo(float32x4_t x, float y) { return x + y; } where C also fails for years with -fexcess-precision=standard.
