MIPS-helpers

Some quality of life stuff for MIPS. Kinda like language extensions in a big ugly python script.

Usage:

emips.py inputfilename

emips.py

If the input file ends in .fs, it automatically sets the output file, with a .s extension. Otherwise it asks for the output file name.

Helps you automatically set up stack frames and allows aliasing of registers.

Also includes Notepad++ language files for the small language extensions

Commands:

@FUNCTION/@function and !FUNCTION/!function

Designate a block of code as a function. Without the @FUNCTION designation, other things won't run. Requires argument: name=fname

.alias

Alias a register. See demo images.

.stacksave

Saves certain registers to the stack, and then resets them when tearing the stack down. (Use for S registers)

Example usage: .stacksave $s0 $s1

.stackalloc

Sets up and tears down a stack frame with aliased stack variables of specified sizes.

lstk (Load Stack)

Load an aliased stack variable. Compiles to lw with an offset.

sstk (Store Stack)

Store an aliased stack variable. Compiles to sw with an offset.
