please help!!

In the space below, write MIPS code for a leaf subroutine mymul that will compute x = y*z;. Although there are many ways to do a multiply, here's C code for one of them that you might want to use: extern int x, y, z; void my mul(void) {/* do x = y * z the hard way... */int t0 = 0; int t1 = 1; int t2 = y; int t3 = z; while (t1 ! = 0) {if (t1 & t3) ! 0) {t0 += t2;} t1 += t1; t2 += t2;} x = t0;} #### # # Multiplication routine: # # x = y * z # .text .globl mymul mymul: # # Your code here # jr $ra #return
