The simplest set up for working on a plugin.

To build the plugin

cabal new-build plugin

To test the plugin

cabal new-test test

Using the LateCCPlugin

To use the plugin on a package:

• Add the plugin as a dependecy to the package like any other package.
• Enable profiling and disable automatic insertion of cost centres:

profiling: true

• Add a ghc option to enable the plugin for the package: ghc-options: -fplugin=LateCCPlugin

And that's it! This will disable the default method of const centre insertion and instead insert cost centres at the end of the compilation pipeline.
