Question

Please turn this C code into pseudo-assembly (NOT NORMAL ASSEMBLY): unsigned int multiply_unsigned(unsigned int a, unsigned int b){ unsigned int res; unsigned int ta; unsigned int tb; res = ((unsigned int) 0); ta = a; tb = b; for (int i = 0; i < (sizeof(a) << 3); i++){ //compare to 32 first if ((ta & ((unsigned int) 1)) != ((unsigned int) 0)){ res += tb; } ta >>= 1; tb <<= 1; } return res; }

          Please turn this C code into pseudo-assembly (NOT NORMAL ASSEMBLY):

unsigned int multiply_unsigned(unsigned int a, unsigned int b){
    unsigned int res;
    unsigned int ta;
    unsigned int tb;
    res = ((unsigned int) 0);
    ta = a;
    tb = b;
    for (int i = 0; i < (sizeof(a) << 3); i++){ //compare to 32 first
        if ((ta & ((unsigned int) 1)) != ((unsigned int) 0)){
            res += tb;
        }
        ta >>= 1;
        tb <<= 1;
    }
    return res;
}
