More related problems -- do they deserve their own bug reports?
1. The following workaround provided by Jakub
doesen't solve the #error problem:
> #pragma GCC push_options
> #pragma GCC target ("aes")
> #include <wmmintrin.h>
> #pragma GCC pop_options
It is reported by checking the __AES__ macro, which is not
defined by #pragma GCC target ("aes"). Similarly with
target("sse4.1") and __SSE_4_1__ form nmmintrin.h.
2. Additionally, the use of intrinsic _mm_aeskeygenassist_si128,
implemented as shown below:
_mm_aeskeygenassist_si128 (__m128i __X, const int __C)
{
return (__m128i) __builtin_ia32_aeskeygenassist128 ((__v2di)__X, __C);
}
aborts compilation (on 4.7.2) claiming that the
__builtin_ia32_aeskeygenassist128 function explicitly
requires "-maes" in the command line, despite the fact
it is used within a block surrounded by #pragma GCC target ("aes").
