To get started

Run this command on the command line clone the repo.

git clone https://github.com/acm-uncc/mipsvm.git

To add a new feature

Find an instruction here that is not already implemented (or pick one from our list below)
git branch (instruction name)
git checkout (instruction name)
Identify instruction layout
Create function with op_ + function name
First argument to function will be MIPS32_VM& vm
Other arguments will be instruction layout (except for the first section)
Implement function according to what the page says
Go to op_handlers array, find the opcode (first number) that corresponds to a number on the list
Change nullptr with the name of the function you implemented like reinterpret_cast(name)
Go to here
Figure out type of instruction based on page 73
Look through enum of OP_TYPE
Go to op_types array and find the opcode of your function
Replace UNIMPLEMENTED with OP_TYPE
git add .
git commit -m "Add (instructin name)"
git push origin master
Go to the repository then the Pull requests tab
Hit new pull request
Select your branch
Create pull request and mention which instruction you did in the title
