Code Generation II (codegen2) Project
COP-3402

Be sure to complete the git exercise before attempting this project.

Create a new local repository, following the directions in the git exercise (including the git --set-upstream last step) and set the local and remote repository URLs to be the following locations:

Download and untar the project template. The template has only been created and tested for use on eustis. You will create a new git repo and start it with a fresh copy of template for each separate codegen project.

cd ~/cop3402spring25/codegen2
wget https://www.cs.ucf.edu/~gazzillo/teaching/cop3402spring25/files/compiler-project.tar
tar -xvf compiler-project.tar
mv CodeGen.template.cpp CodeGen.cpp

Be sure that you include all files from the project template in your repo.

The following will build your compiler (tested on eustis):

cd ~/cop3402spring25/codegen2
make

The result is a program called CodeGen.

Included are also a number of files prefixed with SimpleIR which includes the grammar (SimpleIR.g4) and generated parser files.

Again, be sure that you include all files from the project template in your repo so that it builds with make.

You can make a fresh clone of your repo to test that it builds properly.

You can sanity check your empty CodeGen template by giving it a SimpleIR program, e.g.,

./CodeGen << EOT
function main
return 0
end function
EOT

You should see no errors.

Add, commit, and push CodeGen.cpp along with all other files included in the project template. Don't forget to commit and push changes to CodeGen.cpp as you complete the project.

Here is a quick way to add all the required files:

git add CodeGen.cpp $(tar -tf compiler-project.tar | grep -v 'CodeGen.template.cpp')

Be sure to commit and push them as well.

See the hello project for instructions on cloning a project from the grading server.

In brief, you can sanity check your repo on the grading server with the following:

git clone gitolite3@eustis3.eecs.ucf.edu:cop3402/$USER/codegen2 ~/tmp/codegen2_selfcheck
cd ~/tmp/codegen2_selfcheck
make
./CodeGen << EOT
function main
return 0
end function
EOT

If any of these steps fail, then your project is likely not submitted correctly and will fail grading. Keep in mind that while necessary, passing the above steps is not sufficient for demonstrating a correctly-working compiler. See the descriptions of the test cases and grading criteria below for more information.

All test cases use this SimpleIR template. Be sure to follow the project requirements to hard-code the function-related listeners for this template.

function main # DO NOT CHANGE
localVariables a b c d e f g result retval # DO NOT CHANGE
# add your code to try out here
retval := call print_int result # DO NOT CHANGE
return 0 # DO NOT CHANGE
end function # DO NOT CHANGE
