* Generalise reallyUnsafePtrEquality# and use itsheaf2021-07-231-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fixes #9192 and #17126 updates containers submodule 1. Changes the type of the primop `reallyUnsafePtrEquality#` to the most general version possible (heterogeneous as well as levity-polymorphic): > reallyUnsafePtrEquality# > :: forall {l :: Levity} {k :: Levity} > (a :: TYPE (BoxedRep l)) (b :: TYPE (BoxedRep k)) > . a -> b -> Int# 2. Adds a new internal module, `GHC.Ext.PtrEq`, which contains pointer equality operations that are now subsumed by `reallyUnsafePtrEquality#`. These functions are then re-exported by `GHC.Exts` (so that no function goes missing from the export list of `GHC.Exts`, which is user-facing). More specifically, `GHC.Ext.PtrEq` defines: - A new function: * reallyUnsafePtrEquality :: forall (a :: Type). a -> a -> Int# - Library definitions of ex-primops: * `sameMutableArray#` * `sameSmallMutableArray` * `sameMutableByteArray#` * `sameMutableArrayArray#` * `sameMutVar#` * `sameTVar#` * `sameMVar#` * `sameIOPort#` * `eqStableName#` - New functions for comparing non-mutable arrays: * `sameArray#` * `sameSmallArray#` * `sameByteArray#` * `sameArrayArray#` These were requested in #9192. Generally speaking, existing libraries that use `reallyUnsafePtrEquality#` will continue to work with the new, levity-polymorphic version. But not all! Some (`containers`, `unordered-containers`, `dependent-map`) contain the following: > unsafeCoerce# reallyUnsafePtrEquality# a b If we make `reallyUnsafePtrEquality#` levity-polymorphic, this code fails the current GHC representation-polymorphism checks. We agreed that the right solution here is to modify the library; in this case by deleting the call to `unsafeCoerce#`, since `reallyUnsafePtrEquality#` is now type-heterogeneous too.

* Make reallyUnsafePtrEquality# levity-polymorphicsheaf2021-06-251-0/+0
| | | | fixes #17126, updates containers submodule
* Fix array and cleanup conversion primops (#19026)Sylvain Henry2021-03-031-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first change makes the array ones use the proper fixed-size types, which also means that just like before, they can be used without explicit conversions with the boxed sized types. (Before, it was Int# / Word# on both sides, now it is fixed sized on both sides). For the second change, don't use "extend" or "narrow" in some of the user-facing primops names for conversions. - Names like `narrowInt32#` are misleading when `Int` is 32-bits. - Names like `extendInt64#` are flat-out wrong when `Int is 32-bits. - `narrow{Int,Word}<N>#` however map a type to itself, and so don't suffer from this problem. They are left as-is. These changes are batched together because Alex happend to use the array ops. We can only use released versions of Alex at this time, sadly, and I don't want to have to have a release thatwon't work for the final GHC 9.2. So by combining these we get all the changes for Alex done at once. Bump hackage state in a few places, and also make that workflow slightly easier for the future. Bump minimum Alex version Bump Cabal, array, bytestring, containers, text, and binary submodules

* Update to (unreleased) `deepseq-1.4.0.0`Herbert Valerio Riedel2014-11-151-0/+0
| | | | | | | | | | | | | | | | | | | This pulls in the new `Generic`-based `-XDefaultSignature`-based default implementation for `rnf`[1], and will be interesting to use in combination with the soon to be merged `-XDeriveAnyClass` extension. This requires updating several other submodules as well in order to relax the upper bound on `deepseq` and/or in a few cases to avoid relying on the default method implementation of `rnf`: - `Cabal` - `bytestring` - `containers` - `parallel` - `process` - `time` [1]: http://permalink.gmane.org/gmane.comp.lang.haskell.libraries/23031
