Converting C++ to MIPS

manpreet Best Answer 2 years ago

Hello I've recently started working with MIPS and have been converting some of my old projects (in C++) onto MIPS. I thought I did everything correctly, but when I started to compile it assembled but I didnt get expected results. The little snippet I'm showing you should be able to do a full loop but stops midway through for some reason.I would add all the code but its over 500 lines long and dont want to make it a bigger problem.

I think the problem deal with this reading in the *hopPtr1 I've tried altering the sw but I couldn't find the problem

begDW1:
#                  used1 = 0;
                   li $t1, 0
#                  hopPtr1 = a1;
                   la $t4, array
#//                do
begDW2:
#                  cout << einStr;
                   li $v0, 4
                   la $a0, einStr
                   syscall
#                  cout << (used1 + 1);
                   li  $v0, 1
                   addi $a0, $t1,1
                   syscall
#                  cout << ':' << ' ';
                   li $v0, 4
                   la $a0, colSpa
                   syscall 
#                  cin >> *hopPtr1;   
                   li $v0,5
                   syscall
                   sw $v0, 0($t4)                          
#                  ++used1;
                   addi $t1,$t1,1
#                  ++hopPtr1;
                   addi $t4,$t4,1          
#//                if (used1 == 12)
#                  if (used1 != 12) goto else1;
                   li $t0, 12
                   bne $t1, $t0, else1
begI1:
#                  cout << moStr;
           li $v0, 4
           la $a0, moStr
           syscall 
#                  cout << 12;
           li $v0, 1
           li $a0, 12
           syscall
#                  cout << ieStr;
           li $v0, 4
           la $a0, ieStr
           syscall
#                  cout << endl;
                   li $v0, 11
                   li $a0, '\n'
                   syscall
#                  reply = 'n';
                   li $t8,'n'
#                  goto endI1;
                   j endI1
#//                }
else1:
#//                {
#                  cout << emiStr;
                   li $v0, 4
                   la $a0, emiStr
                   syscall
#                  cin >> reply;
           li $v0, 12
                   syscall
                   move $t8, $v0

The loop should be repeated 12 com/tag/times">times and not stopped midway through the 2nd loop
