From 91c6b1f54aea658b0056caec45655475897f1972 Mon Sep 17 00:00:00 2001 From: Ben Gamari Date: Fri, 30 Oct 2015 20:22:42 +0100 Subject: Generate Typeable info at definition sites This is the second attempt at merging D757. This patch implements the idea floated in Trac #9858, namely that we should generate type-representation information at the data type declaration site, rather than when solving a Typeable constraint. However, this turned out quite a bit harder than I expected. I still think it's the right thing to do, and it's done now, but it was quite a struggle. See particularly * Note [Grand plan for Typeable] in TcTypeable (which is a new module) * Note [The overall promotion story] in DataCon (clarifies existing stuff) The most painful bit was that to generate Typeable instances (ie TyConRepName bindings) for every TyCon is tricky for types in ghc-prim etc: * We need to have enough data types around to *define* a TyCon * Many of these types are wired-in Also, to minimise the code generated for each data type, I wanted to generate pure data, not CAFs with unpackCString# stuff floating about. Performance ~~~~~~~~~~~ Three perf/compiler tests start to allocate quite a bit more. This isn't surprising, because they all allocate zillions of data types, with practically no other code, esp. T1969 * T1969: GHC allocates 19% more * T4801: GHC allocates 13% more * T5321FD: GHC allocates 13% more * T9675: GHC allocates 11% more * T783: GHC allocates 11% more * T5642: GHC allocates 10% more I'm treating this as acceptable. The payoff comes in Typeable-heavy code. Remaining to do ~~~~~~~~~~~~~~~ * I think that "TyCon" and "Module" are over-generic names to use for the runtime type representations used in GHC.Typeable. Better might be "TrTyCon" and "TrModule". But I have not yet done this * Add more info the the "TyCon" e.g. source location where it was defined * Use the new "Module" type to help with Trac Trac #10068 * It would be possible to generate TyConRepName (ie Typeable instances) selectively rather than all the time. We'd need to persist the information in interface files. Lacking a motivating reason I have not done this, but it would not be difficult. Refactoring ~~~~~~~~~~~ As is so often the case, I ended up refactoring more than I intended. In particular * In TyCon, a type *family* (whether type or data) is repesented by a FamilyTyCon * a algebraic data type (including data/newtype instances) is represented by AlgTyCon This wasn't true before; a data family was represented as an AlgTyCon. There are some corresponding changes in IfaceSyn. * Also get rid of the (unhelpfully named) tyConParent. * In TyCon define 'Promoted', isomorphic to Maybe, used when things are optionally promoted; and use it elsewhere in GHC. * Cleanup handling of knownKeyNames * Each TyCon, including promoted TyCons, contains its TyConRepName, if it has one. This is, in effect, the name of its Typeable instance.
