Easy way to clear registers in mips assembly?

[TGCid]

This is my first time experience with mips assembly. I am using spim. We are doing the program where after some manipulation, the program loops back to the beginning unless a quit command is given. My problem is that I don't know what registers I messed with but after the 1st loop, some weird behaviors would occur. I think it is the fault of the registers not being reset. How would you reset all the registers back to the way it was when you first run the code? Thanks.

Ummm, copy all the values in the registers into the stack before modifying them. Technically, the only ones you need to copy are the caller-saved ones, but practically there is no difference. When you need to recall the values just read them from the stack.

Spim is fun.

Brings back bad memories of my OS class.

What he said. I don't have any experience with MIPS; at our school, CPE's use MIPS, and EE's program for the MC68000. But from what you've described, it seems comparable (the only difference I can remember is, I believe, MIPS has more address registers than the 68.

this is totally off topic but maybe this isn't the right forum for this 😉
