ghc-dump
is a library, GHC plugin, and set of tools for recording and
analysing GHC's Core representation. The plugin is compatible with GHC 7.10
through 8.3, exporting a consistent (albeit somewhat lossy) representation
across these versions. The AST is encoded as CBOR, which is small and easy to
deserialise.
.
This package provides the AST and compiler plugin. See the ghc-dump-util
package for a useful command-line tool for working with dumps produced by this
plugin.

GhcDump.Plugin
provides a Core-to-Core plugin which dumps a representation
of the Core AST to a file after every Core-to-Core pass. To use it, simply
install this package and add -fplugin GhcDump.Plugin
to your GHC
command-line. See the README
for further analysis tips.
