Looping through strings 1 character at a time in MIPS

Question

I'm having issues grasping the concept of string and characters in MIPS. If I'm trying to loop through two strings, and concatenate two characters at a time, how would I do this?

Lets say I have

String1 = "St"
String2 = "ack"

How could I loop through to get

Sa, Sc, Sk, ta, tc, tk

Thanks in advance!

Can you write us the pseudocode you think would do it, and whatever MIPS code you have so far? — John Zwinck, Apr 27 '11 at 01:24

the most easy way to do this:

1)write the program with C.

2)compile it with GCC with flags "-S", and use "> xx.S" to store the assembly code to a file.

3)extract the assembly codes from "xx.S".

This only works on a Mips machine, as I don't have a cross compiler. – Parker Jun 07 '11 at 17:31
maybe you can try 'buildroot' a dummy tool. – wuxb Jun 07 '11 at 19:04
From what I've read, it's extremely difficult to make a GCC cross compiler from x86 to MIPS? – Parker Jun 08 '11 at 17:33
you can just make binutils & partial gcc (make all-gcc, make install all-gcc) that don't need the libc, and I have succeed to it. – wuxb Jun 09 '11 at 01:48

Wasn't able to figure it out, the MIPS environment I used had something built in apparently.
