#6135: Unboxed Booleans ---------------------------------+------------------------------------------ Reporter: benl | Owner: jstolarek Type: feature request | Status: patch Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.4.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: #605 | ---------------------------------+------------------------------------------ Comment(by benl): I vote for changing the existing primops to use Word#, and don't bother supporting the existing Bool returning versions. I think we can get away with changing the existing types because it's trivial to update client code to use the new versions. You just need to add (tagToEnum# (word2Int# ...)). I vote for making the primops return Word# instead of Int#. I know that this requires an extra word2Int# conversion when using tagToEnum#, but there is really no reason to suggest that the result of a boolean comparison operator might be negative! I suspect the reason tagToEnum# currently takes an Int# is because literals like 5# are Int#. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/6135#comment:31> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #7812: Ambiguity check too eager with unconstrained type variable

#7812: Ambiguity check too eager with unconstrained type variable -----------------------------+---------------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Component: Compiler (Type checker) Version: 7.7 | Keywords: AmbiguityCheck Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: None/Unknown | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- Consider the following code: {{{ {-# LANGUAGE TypeFamilies, DataKinds, GADTs #-} type family F (b :: Bool) a type instance F False a = a type instance F True a = Int data SBool :: Bool -> * where SFalse :: SBool False STrue :: SBool True foo :: SBool b -> [F b a] foo _ = [] }}} GHC 7.6.1 compiles this code without a problem, and both {{{foo STrue}}} and {{{foo SFalse}}} are well typed and evaluate to {{{[]}}}. HEAD (even after yesterday's ambiguity patch for #7804) does not compile this code, complaining about ambiguity. Here is the error: {{{ Couldn't match type ‛F b a0’ with ‛F b a’ NB: ‛F’ is a type function, and may not be injective The type variable ‛a0’ is ambiguous Expected type: SBool b -> [F b a] Actual type: SBool b -> [F b a0] In the ambiguity check for: forall (b :: Bool) a. SBool b -> [F b a] In the type signature for ‛foo’: foo :: SBool b -> [F b a] }}} This is admittedly a weird corner case, but it's one I've run into in real(ish) code. On first glance, the type variable {{{a}}} really is ambiguous in the type signature for {{{foo}}}. But, it turns out that this is a benign ambiguity, because the variable is either ignored or, after type family simplification, appears in an inferrable location within the type. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7812> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

Furthermore, the arithmetic types already allow (*) via Num, so it'd be nice to have them be Integral types so that we have div, too. I propose we include Bits, Enum, and Integral instances for CTime and friends.

For that I need to know which approach to choose: * Add new primops and leave the old ones unmodified, or * Change the existing primops so that they return an Int# + add some wrappers (Int# -> Int# -> Bool and so on). I think that the second option will not be backwards compatible - not sure if that's acceptable. OTOH I think it would simplify GHC code in some places, i.e this change seems to be more about removing code than adding. I'm unable to decide which approach is the preferred one - people more experienced than me should decide. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/6135#comment:30> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
