--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Perhaps the HAVE_AVX512F configure test is too simple for the SEH purposes.
I've tried:
typedef double __m512d __attribute__ ((__vector_size__ (64)));
typedef double __m256d __attribute__ ((__vector_size__ (32)));
__m512d foo (__m512d, __m512d, __m512d, __m512d, __m512d, __m256d,
__m512d, __m512d);
__m512d _mm512_add (__m512d a, __m256d c)
{
__m512d b = __builtin_ia32_addpd512_mask (a, a, a, 1, 4);
__m512d f = __builtin_ia32_addpd512_mask (b, a, a, 1, 4);
__m512d g = __builtin_ia32_addpd512_mask (f, a, a, 1, 4);
__m512d h = __builtin_ia32_addpd512_mask (g, a, a, 1, 4);
__m512d e = foo (b, a, b, a, b, c, b, b);
return __builtin_ia32_addpd512_mask (b, e, a, 1, 4) + f + g + h;
}
int
main ()
{
;
return 0;
}
but that still doesn't generate any .seh_savexmm directives (at least not in my
cross-compiler).
