Outline

Here is the outline of the program. The comments show the major sections of the program.

In designing a program, you should always decide on the major steps and on the order they should be performed. It is helpful to document this in the program.

        .text
        .globl  main
main:  
        # 

        # 

        # 

        # 

        .data
str:    .space  128     # character buffer

Not much of an outline. Luckily, here are some phrases you can use to fill in the blanks:

print the reversed string
push each character onto the stack
input the string into a buffer
pop chars from stack back into the buffer
