This is a class project for ECE566: Compiler Optimization and Scheduling at NC State

Running Locally

Build a docker container using the docker file provided.

docker build -t llvmp3:latest .

Build Executable

Get into the docker container

docker run -v $(pwd):/ece566 -it llvmp3:latest /bin/bash

Create a build directory

mkdir build

Run cmake

cmake ..

Now run make

make

Building Test

Create a test directory in the root folder and cd into it

mkdir test
cd test

Configure the benchmark tool to find the executable that we built earlier

/ece566/wolfbench/wolfbench/configure --enable-customtool=/ece566/build/p3

Running Test

while you are in the test directory, run the following command to compile all the benchmark.

make all test

To ensure that our optimization pass did not break things, run the following:

make test compare
