• create a directory that will contain all of the input files for the invokation
• put a compile command into <dir>/compile.sh (see e.g. compile_example.sh; it will be invoked as ./compile.sh input.c -o output.o)
• gcc -E -P -I header_dir -D'__attribute__(x)=' orig_c_file.c > <dir>/base.c
• python3 strip_other_fns.py <dir>/base.c func_name
• put asm for func_name into <dir>/target.s, with the following header:

.set noat
.set noreorder
.set gp=64
.macro glabel label
    .global \label
	.type \label, @function
    \label:
.endm

• mips-linux-gnu-as -march=vr4300 -mabi=32 <dir>/target.s -o <dir>/target.o
• optional sanity checks:
  • <dir>/compile.sh <dir>/base.c -o <dir>/base.o
  • ./diff.sh <dir>/target.o <dir>/base.o
• ./permuter.py <dir>
