I believe this is the reproducer:

bulldozer:~$ g++ -march=bdver1 -msse4.1 test.cxx
test.cxx: In function ‘int main(int, char**)’:
test.cxx:15:9: error: ‘_mm_roti_epi64’ was not declared in this scope
     b = _mm_roti_epi64(a, 1);
         ^~~~~~~~~~~~~~
test.cxx:15:9: note: suggested alternative: ‘_mm_rorv_epi64’
     b = _mm_roti_epi64(a, 1);
         ^~~~~~~~~~~~~~
         _mm_rorv_epi64

bulldozer:~$ cat test.cxx
#ifdef __XOP__
#include <immintrin.h>
#include <ammintrin.h>
#endif

#ifdef __SSE41__
#include <smmintrin.h>
#endif

int main(int argc, char* argv[])
{
    __m128i a=_mm_setzero_si128(), b=_mm_setzero_si128(), c;

#ifdef __XOP__
    b = _mm_roti_epi64(a, 1);
#endif

#ifdef __SSE41__
    c = _mm_blend_epi16(a, b, 0);
#endif

    return 0;
}
