Hi Csaba,
The transformations you described already exist as core simplifier passes.
For custom compilation, you may write your own pass using the core plugin
mechanism, see
https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/extending_gh...
It's also possible to perform transformations on STG, but it takes extra
effort to retrieve/transform the in-memory STG representations, and type
safety is also not guaranteed.

Shao Cheng

Hello,
I wonder what is the easiest way to compile Haskell to supercombinators (top level functions) using GHC as a library.
Is it possible to use GHC simplifier to transform the parsed Haskell source to supercombinators? i.e. to do
- eta expansion - closure conversion - lambda lifting
Or should it be written from scratch?
Is Core or STG suited better for this purpose?
Thanks, Csaba
