When debugging musl builds, I often have to sift through thousands of lines
of `nix-store -q --tree` or `nix-store -qR` output.
Until now, `pkgsMusl` and normal `pkgs` GHCs looked exactly the same in
there, making that task tough.
Same for `integer-simple`, which makes debugging `gmp` issues easier.
This commit introduces a suffix to tell them apart easily.
Note that this is different from `targetPrefix` which is for
cross-compilation, which `pkgsMusl` does not do.
For GHC HEAD, integer-simple no longer exists, instead we now have a
“bignum backend”, so we just call the integer-simple successor
native-bignum.

Let's remove peti (retired) as well Marc, Andres and Will who haven't
been active lately. Feel free to re-add yourself, but this should at
least lessen the GitHub notifications for now.
Add lib.teams.haskell to every maintainer list additionally. I've also
added Domen and Pavol to GHC 8.10.7 binary since they are the only ones
working on aarch64-darwin so far. Let me know if that is alright with
you.
Compiling GHC on Hydra takes 3h or more (with -j2) whereas even on an
outdated CPU GHC can be compiled in under an hour with -j4. To get a
higher NIX_BUILD_CORES value at build time, we'll have to mark GHC
big-parallel.
Building `haskell.compiler.ghcHEAD` on Hydra on Darwin seemed to cause
frequent timeouts.
Here's an example of a timeout: https://hydra.nixos.org/build/149762652
This commit raises the timeout time on Hydra for ghcHEAD. The other
GHC derivations have this set, so it makes sense to set this here
as well.
Adds new package options:
* enableDocs
* enableHaddockProgram
to control whether to build Sphinx docs, and GHC haddocks and the
haddock program.
Unfortunately currently the building of the `haddock `program
and generating GHC docs are mixed into one option, see:
https://gitlab.haskell.org/ghc/ghc/-/issues/20077
Making Sphinx docs disableable, and disabling them by default
for Musl and cross builds, makes it much easier to provide these
builds without having to support Sphinx's enormous dependency
tree for those ways of building.
useLdGold previously just checked for useLLVM which (currently) implies
`linker == "lld"`. However more accurate is to check the `linker` of the
`targetPlatform` as it actually tells us which bintools package we can
expect.
`linker == "bfd"` implies that we are using the `binutils` package, so
gold is available, so we can use it unless musl is the libc. `linker ==
"gold"` implies that gold is the default linker already and we should
absolutely use it.
GHC calls otool on darwin which is contained in the
stdenv.cc.bintools.bintools derivation and thus needs adding to the
runtime PATH of GHC. Since this is toolchain specific technically, we
check for cctools instead of darwin (although I don't know if GHC
or nixpkgs work on macOS without cctools).
This fixes usage of GHC in an environment where otool is not available
and more specifically in stdenvNoCC which is used by writers.writeHaskell.
Resolves#123228.
The broken build of ghcHEAD on aarch64-linux results from rts/Libdw.c
not supporting that platform. Seemingly this particular file is only
relevant for DWARF support in GHC, so we disable that on unsupported
platforms.
* ghcHEAD: bump to 8.11.20200403
* ghcHead: reduce diff vs. 8.10.1
dontAddExtraLibs was removed by accident (IMO) in ea19a8ed1e
* ghcHEAD: add ability to use system libffi
- enable nixpkgs' libffi
- minimise diffs against 8.10.1
- remove patching
* remove configure warning about --with-curses-includes
configure: WARNING: unrecognized options: --with-curses-includes
