Reduced code is:

char a;
char *b;
int c;
void f(void) 
{
        char *d = f;
        int e;
        for(;e;e++)
        {
                d[4*e] = a*(256-c) + b[4*e]*c >> 8;
                d[4*e+1] = a*(256-c) + b[4*e+1]*c >> 8;
                d[4*e+2] = a*(256-c) + b[4*e+2]*c >> 8;
                d[4*e+3] = a*(256-c) + b[4*e+3]*c >> 8;
        }
}
