Re: Fat interface files?

Right, my understanding is that they are not sufficient however, as Michael layed out here https://gitlab.haskell.org/ghc/ghc/-/wikis/Core-interface-section#unfoldings This should be linked together better. We'll improve this. On Wed, Oct 21, 2020 at 5:56 PM Simon Peyton Jones wrote:

Thanks Mortiz

That wiki page is about extensible interface files in general. It says nothing about specifically putting Core terms into interface files.

For the Core part, since GHC already puts Core into unfoldings, the simple thing is just to expose all unfoldings, no?

Just to make sure we are aware of all the ongoing efforts. We've been working on ebedding Core into interface files as well.

Josh has updated the Wiki page here https://gitlab.haskell.org/ghc/ghc/-/wikis/Extensible-Interface-Files https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgitlab.haskell.org%2Fghc%2Fghc%2F-%2Fwikis%2FExtensible-Interface-Files&data=04%7C01%7Csimonpj%40microsoft.com%7C644d055c20ed4377753c08d875a4cfa1%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637388698431720509%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=5xMRK5FF7OKifyceURAEkcNzo6naUzvLkRWnsCto7pc%3D&reserved=0 .

Hi Edward,

While chatting with the ghc-ide folks recently I realized that it would be useful to be able to preserve Core such that compilation can be restarted (e.g. to be pushed down the bytecode pipeline to evaluate TH splices).

As I recall this is precisely what you implemented in your "fat interface file" work. Do you recall what the state of this work was? Do you have a branch with last-known-good work? Do you recall any tricky questions that remained outstanding?

Cheers,
