Without optimization main() preprocesses to
int main() {
((__m128i)__builtin_ia32_pshufd ((__v4si)Vec(5), (((3) << 6) | ((3) << 4) |
((3) << 2) | (3))));
}
with optimization we get instead
int main() {
_mm_shuffle_epi32(Vec(5), (((3) << 6) | ((3) << 4) | ((3) << 2) | (3)));
}
because with optimization we use an inline function instead of a macro.
Uros - it was you who changed that (and I see it may not be too easy to
make all parties happy here). My suggestion is to force the same "argument"
type by doing
#define _mm_shuffle_epi32(__A, __B) \
((__m128i)__builtin_ia32_pshufd ((__v4si)(__m128i)__A, (int)__B))
instead of
#define _mm_shuffle_epi32(__A, __B) \
((__m128i)__builtin_ia32_pshufd ((__v4si)__A, __B))
to match the prototype of _mm_shuffle_epi32 which reads
static __inline __m128i __attribute__((__always_inline__, __artificial__))
_mm_shuffle_epi32 (__m128i __A, const int __mask)
{
return (__m128i)__builtin_ia32_pshufd ((__v4si)__A, __mask);
}
and adjust all !__OPTIMIZE__ macro variants this way. (at least this makes
this testcase work properly)
