Reduced source:
typedef unsigned int word;
typedef int __m64 __attribute__ ((__mode__ (__V2SI__)));
typedef int __v2di __attribute__ ((mode (V2DI)));
void P4Optimized_Multiply41(word *C)
{
__m64 s1;
__v2di temp[7];
word * temp819;
temp819 = (word *)&temp[0];
C[7] = (unsigned int)(int)(long long int)s1 + temp819[27];
return;
}
