Hi Dimitry, ghc-core is a pretty-printer for GHC's internal Core language (you can get a non-pretty-printed version simply by compiling with (IIRC) -dverbose-core2core). This is what we actually optimize and generate code from, and the formatting of this output might change at any time. This is probably what you should be looking at, as a human trying to understand how your programs are being complied.
extcore is a library that parses "external" Core, which is an alternative format intended to be stable and hence a suitable target for consumption by non-GHC tooling. You can have GHC output external core instead of machine code / C. I don't believe this is widely used yet.
