Check e.g. `Result size of Tidy Core` which seems to have 3x as many terms for ghc, and `Simplifier [Mymodule]` doesn't seem to run in ghci The first time terms are different is at `Desugar, the first time a factor 3 comes in is after `Specialize`. > bgamari: wow, it sounds like the simplifier isn't getting run as aggressively in GHCi I'm running this on Ubuntu 16.04 inside nix (but happens the same way outside nix). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/12847> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #10170: Find versioned versions of LLVM tools

#10170: Find versioned versions of LLVM tools -------------------------------------+------------------------------------- Reporter: erikd | Owner: erikd Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 (LLVM) | Operating System: Unknown/Multiple Keywords: | Type of failure: None/Unknown Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Since it has become more widely know that the LLVM developers often make breaking changes to the IR language between releases, some Linu distributions (eg Debain and hence Ubuntu) have started doing multi- version LLVM installs. For instance on Debian, the llvm-3.6 programs are installed in `/usr/lib/llvm-3.6/bin` as `llc` and `opt`. I propose that the `configure.ac` and `aclocal.m4` configuration goop be modified to look for `llc` and `opt` in these versioned `/usr/lib/llvm-X.Y` locations. I'm also willing to do the hard yards on implementing this if people think its a good idea. This can be seen as a step along the way to more stringent LLVM versioning requirements. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10170> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#12564: Type family in type pattern kind -------------------------------------+------------------------------------- Reporter: int-index | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.0.1 (Type checker) | Keywords: TypeInType, | Operating System: Unknown/Multiple TypeFamilies | Architecture: | Type of failure: GHC rejects Unknown/Multiple | valid program Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- I want to write a type family that is analogous to `!!` for lists but requires the index to be no bigger than the length of the list. Usually, in dependently typed languages finite sets are used for this purpose, here's an attempt to do so in Haskell: {{{#!haskell {-# LANGUAGE TypeInType, TypeFamilies, GADTs, TypeOperators #-} import Data.Kind data N = Z | S N type family Len (xs :: [a]) :: N where Len '[] = Z Len (_ ': xs) = S (Len xs) data Fin :: N -> Type where FZ :: Fin (S n) FS :: Fin n -> Fin (S n) type family At (xs :: [a]) (i :: Fin (Len xs)) :: a where At (x ': _) FZ = x At (_ ': xs) (FS i) = At xs i }}} It fails to compile with this error: {{{ FinAt.hs:16:3: error: • Illegal type synonym family application in instance: 'FZ • In the equations for closed type family ‘At’ In the type family declaration for ‘At’ }}} That's because the kind of the `FZ` pattern (first clause of `At`) has the kind `Fin (Len xs)` and the application of `Len` cannot reduce completely. `checkValidTypePat` then disallows the pattern, as it contains a type family application. I tried to suppress `checkValidTypePat` and the definition of `At` has compiled; however, it's of little use, since `At` doesn't reduce: {{{#!haskell x :: At '[Bool] FZ x = True }}} results in {{{ FinAt.hs:20:5: error: • Couldn't match expected type ‘At * ((':) * Bool ('[] *)) ('FZ 'Z)’ with actual type ‘Bool’ • In the expression: True In an equation for ‘x’: x = True }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/12564> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

When using `-fexternal-interpreter`, we can statically link the required packages and object files into a new iconv binary, and use that as our external interpreter. This would mean we could support TH and even limited GHCi without needing a dynamic linker of any kind, which is extremely cool.

But we do: {{{ :info ($) Prelude> :i ($) ($) :: forall (r :: GHC.Types.RuntimeRep) a (b :: TYPE r). (a -> b) -> a -> b -- Defined in ‘GHC.Base’ }}} This happens because the runtime-rep-suppression happens on `Type`, but for `:info` we use `pprInfo` which uses `tyThingToIfaceDecl` and then prints it. And `tyThingToIfaceDecl` doesn't know about the `-fprint- explicit-runtime-reps` flag; and I'd like to keep it that way. We want to change `pprType` to convert to `IfaceType` and then print anyway. I suppose that this means that the pretty-printer for `IfaceType` needs to know about this runtime-rep suppression. That's a bit tiresome, but not impossible, especially since there is no shadowing to worry about. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/11786> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
