Functions

Functions are very simmilar to x86.
Remember to use the calling convention in instructionset.
Floating point $f12 goes in $a0 and $a1.
so if you use $f12 then you skip to $a2.

Creating a function:

.globl funcName
funcName:
    # some code here
jr $ra # jumps to $ra, which is where your code was before

Calling a function:

jal funcName
