Thanks!

I finally got round to doing some Fedora test
<https://koji.fedoraproject.org/koji/taskinfo?taskID=40008521> builds
<https://koji.fedoraproject.org/koji/taskinfo?taskID=40009471>.
LGTM so far, though only tested lightly.

I will be pushing this to the Fedora ghc:8.8 module testing stream soon.

I also built this for fedora in 2 test
<https://koji.fedoraproject.org/koji/taskinfo?taskID=40009944> builds
<https://koji.fedoraproject.org/koji/taskinfo?taskID=40042995> (the latter
for arm).

ps The reason it took so long being that I made some significant packaging
changes earlier for Fedora 31 (added subpackages for prof), which had made
it difficult to build Haskell packages for both F30 and F31.

Hello everyone,

The GHC team is proud to announce the release of GHC 8.8.2. The source
distribution, binary distributions, and documentation are available at

    https://downloads.haskell.org/~ghc/8.8.2

Release notes are also available [1].

This release fixes a handful of issues affecting 8.8.1:

 - A bug (#17088) in the compacting garbage collector resulting in
   segmentations faults under specific circumstances. Note that this may
   affect user programs even if they did not explicitly request the
   compacting GC (using the -c RTS flag) since GHC may fallback to
   compacting collection during times of high memory pressure.

 - A code generation bug (#17334) resulting in GHC panics has been
   fixed.

 - A bug in the `process` library causing builds using `hsc2hs` to fail
   non-deterministically on Windows has been fixed (Trac #17480)

 - A typechecker bug (#12088) resulting in programs being unexpectedly
   rejected has been fixed.

 - A bug in the implementation of compact normal forms resulting in
   segmentation faults in some uses (#17044) has been fixed.

 - A bug causing GHC to incorrectly complain about incompatible LLVM
   versions when using LLVM 7.0.1 has been fixed (#16990).

As always, if anything looks amiss do let us know.

Happy compiling!

Cheers,

- Ben

Subject: GHC 8.8.2 Bootstrap Build Fails on macOS Catalina 10.15,
 undeclared identifier 'TAG_MASK'
Message-ID: <C3401DD9-9B23-4493-AD5D-79706796D04F@gmail.com>

I’m trying to upgrade the MacPorts ghc install to the latest 8.8.2.

The build fails with:
> error: use of undeclared identifier 'TAG_MASK'
> :info:build         return (StgWord)p & TAG_MASK;


This is an error observed with previous ghc versions and on other systems, so I do not believe it is macOS-specific.  Also, the MacPorts build process simply follows the ghc Build & Install instructions: https://github.com/ghc/ghc/blob/master/README.md#building--installing

Is there a simple fix by adding an extra flag somewhere?

Sigh, this is #17146 which should have been backported. I'll have to
investigate how this slipped through the cracks.

Thanks for raising this.

Subject: GHC Full Bootstrap from Source on macOS
Message-ID: <E7C20F00-4D15-4666-A2CF-DB7268824926@gmail.com>

Is there a guide or script to build ghc from source (not the prebuilt binary)?

At MacPorts we’re running into issues on macOS Catalina 10.15 with the bootstrapped-from-prebuilt ghc. See https://trac.macports.org/ticket/59467 .

It would preferable and probably more robust to be able to bootstrap everything from source, and highly preferable to be able to do this with a clang compiler of choice.

Subject: [ANNOUNCE] Glasgow Haskell Compiler 8.10.1-rc1 released
Message-ID: <87muacxhd6.fsf@smart-cactus.org>


Hello all,

The GHC team is happy to announce the availability of the first release
candidate of GHC 8.10.1. Source and binary distributions are
available at the usual place:

    https://downloads.haskell.org/ghc/8.10.1-rc1/

GHC 8.10.1 will bring a number of new features including:

 * The new UnliftedNewtypes extension allowing newtypes around unlifted
   types.

 * The new StandaloneKindSignatures extension allows users to give
   top-level kind signatures to type, type family, and class
   declarations.

 * A new warning, -Wderiving-defaults, to draw attention to ambiguous
   deriving clauses

 * A number of improvements in code generation, including changes

 * A new GHCi command, :instances, for listing the class instances
   available for a type.

 * An upgraded Windows toolchain lifting the MAX_PATH limitation

 * A new, low-latency garbage collector.

 * Improved support profiling, including support for sending profiler
   samples to the eventlog, allowing correlation between the profile and
   other program events

This is the first and likely final release candidate. For a variety of
reasons, it comes a few weeks later than the original schedule of
release late December. However, besides a few core libraries
book-keeping issues this candidate is believed to be in good condition
for the final release. As such, the final 8.10.1 release will likely
come in two weeks.

Note that at the moment we still require that macOS Catalina users
exempt the binary distribution from the notarization requirement by
running `xattr -cr .` on the unpacked tree before running `make install`.

In addition, we are still looking for any Alpine Linux to help diagnose
the correctness issues in the Alpine binary distribution [1]. If you use
Alpine any you can offer here would be greatly appreciated.

Please do test this release and let us know if you encounter any other
issues.

Cheers,

- Ben

Yeah, like how we removed x87 support from code gen except one tiny piece
in the abi, so 32bit x86 code gen is always -msse2 flavor so rounding now
acts sane :)

(A tiny step in a long running make floating point great effort of mine)

Thanks Ben, installed fine on my Mac running 10.14.6.

For the release notes I suggest we document
https://gitlab.haskell.org/ghc/ghc/issues/17341 which is associated with
https://github.com/haskell/cabal/issues/6262 and
https://github.com/haskell/cabal/issues/6104

I realize this will be controversial and may be rejected but I think the
current status is very confusing to new / inexperienced users so I felt I
should suggest it.

As I mentioned in 17341, can we add a milestone and priority to this
feature request?

Thanks again for everybody's work on GHC

Cheers
George
