Usage

1. Install Node.js and GnuPlot:

   • macOS (Using HomeBrew)

     brew install node gnuplot

   • Linux

     sudo apt-get install nodejs gnuplot

2. Install the various modules on which the tools depend:

   npm install

3. Modify the ./update script, change the first argument passed to ./update-readme.js to match that of the clone of llvm-project-prepo used to build the test linkers.

4. Ensure that the linkers are on the path.

5. Run the update script:

   ./update

6. Wait patiently. Generating and linking test data for hundreds or even thousands of binaries can take a very long time! Whilst the tool runs, you’ll see a series of progress bars:

   % ./update
   [----------------------------------------] 0% | ETA: 2 hours | 10/15300 | rld-gen
   

7. Results (both SVG graphs and the raw CSV data) are available in the results directory.
