4ea33def46 haskell generic builder: Disable static libs on Windows because no -staticlib
The reason why this does not work is not that we can't built static
objects, we can, but we can't use `-staticlib` on GHC on windows.
`-staticlib` rolls all dependencies into a combined archive. While this
would work on windows if we used gnu ar and MRI script, GHC can't rely
on GNU ar, and as such has a quick archive concatenation module for GNU
and BSD archives only.

900862ea3b haskell generic builder: setupHaskellDepends should be `nativeBuildInputs
This is because they are just for Setup.hs, so they are just used at build time
and completely isolated from the normal components' dependencies.

This was previous implemented in 8a8f0408cd, but
reverted in e69c7f5641 because it broken
setup-depends non-cross in haskell shell environments (custom Setup.hs in cross
shell environments has never worked). This version adds a special native
exception to avoid that breakage.

ba52ae5048 treewide: isArm -> isAarch32
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.

The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:

```
ISA:             ARMv8   {-A, -R, -M}
                 /    \
Mode:     Aarch32     Aarch64
             |         /   \
Encoding:   A64      A32   T32
```

At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.

The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

65e24f22e6 haskell-generic-builder: Default to window + unix platforms,
Since GHC is a cross compiler, it's perfectly possible to make haskell
binaries on platforms without GHCs. `windows ++ unix` seems good enough
for now.

Also don't default `hydraPlatforms` to `platforms`. The former must be a
list of systems (strings), but the latter is a list of systems or
patterns.

1978fa444d haskell-generic-builder: disable shared executable linking by default
This change raises the question of whether we should disable building of shared
libraries altogether (since we don't link them). Unfortunately, we can't,
because GHC expects shared libraries to be around when building and running
test suites, and no amount of passing --disable-shared flags at configure time
changes the fact. I *guess* that's related to the DYNAMIC_GHC_PROGRAMS = YES
flag we set when building GHC itself, but I haven't investigated it further
yet.

Closes https://github.com/NixOS/nixpkgs/issues/29011.

7f5fba75e2 haskell-generic-builder: compile profiling library variants by default
Unless specified otherwise, the default package set compiles library variants
for profiling with profiling-detail "all-functions". Executables, however, are
not built with profiling enabled.

This change increases the closure size for many Haskell programs, but the
practical advantage of having stack traces and performance measurements easily
available during development seems to outweigh that cost.

016aa581a7 haskell: extend generic builder to recognize mis-configured Cabal 2.x builds
Cabal 1.x says:

 | Warning: This package indirectly depends on multiple versions of the same
 | package. This is highly likely to cause a compile failure.

But in version 2.x, that warning is split into two lines differently:

 | Warning:
 |     This package indirectly depends on multiple versions of the same package. This is very likely to cause a compile failure.

This commit modifies the call to "egrep" to recognize both versions by virtue
of the "-z" flag, which essentially interprets the whole configure-time output
as one long line.

e9e25ec5fe pkgs/haskell-modules: expose haddockDir as passthru variable
WIP

If the `hoogle.nix` file wants to have any sane chance of finding haddock
outputs, the packages need to export the haddock folders as an identifier.

A few TODOs still stand, like passing self to the package instead of needing to
pass it to `haddockDir`. Maybe the exported identifier should be integrated into
the fixpoint somehow instead of using `passthru`?

3cb745d5a6 stdenv: Store one package per line in nix-support/propagated-*
This makes those files a bit easier to read. Also, for what it's worth,
it brings us one baby step closer to handling spaces in store paths.

Also, I optimized handling of many transitive deps with read. Probably,
not very beneficial, but nice to enforce the pkg-per-line structure.
Doing so let me find much dubious code and fix it.

Two misc notes:

 - `propagated-user-env-packages` also needed to be adjusted as
   sometimes it is copied to/from the propagated input files.

 - `local fd` should ensure that file descriptors aren't clobbered
   during recursion.

8a8f0408cd generic-builder: use buildInputs for Haskell dependencies
This actually will matter when I (soon) land cross-compilation support,
and native deps are compiled for the build, instead of host, platform.
But even now, it's good style do this, and one less thing to review
later.

The use of `$nativePkgs` is unfortunate, as it will need to be
swapped out for `$crossPkgs` for build != host builds. This will just a
temporarily cause pain, however, as eventually I will change stdenv to
use a `$runPkgs` (or moral equivalent) in both case.

Closes https://github.com/NixOS/nixpkgs/pull/26480.

00892b7e4e generic-builder.nix: Update doHaddock
By default, `ghcjs` haddocks are precluded from being built. I see no reason to disallow building haddocks on projects built with `ghc` and `ghcjs` (someone can correct me here). `HaLVM` currently does not support `haddock` since it's a Stage 1 `GHC`. https://github.com/GaloisInc/HaLVM/blob/master/src/misc/build.mk.in#L20

Currently, building `haddocks` for `ghcjs` projects requires altering the derivation, which doesn't allow users to take advantage of the cache. This change will relieve that.

7131e06214 haskell: work around linker limits on Mac OS X Sierra.
The Sierra linker added a limit on the number of paths that any one
dynamic library (`*.dylib`) can reference.  This causes problems when
a Haskell library has many immediate dependencies (#22810).

We follow a similar fix as GHC/Cabal/Stack: for each derivation,
create a new directory with symlinks to all the dylibs of its immediate
dependencies, and patch its package DB to reference that directory
using the new `dynamic-library-dirs` field.

Note that this change is a no-op for older versions of GHC, i.e., they will
continue to fail on some packages as before.

Also note that this change causes the bootstrapped versions of GHC to be
recompiled, since they depend on `hscolour` which is built by
`generic-builder.nix`.

Tested by building the `stack` binary as described in #22810.

feffadefed haskell generic-builder: Revert "Pass through the ghcEnv."
This reverts commit a27bc8b317. Please don't add
random stuff to the interface provided by the generic builder without
coordinating with others. There is a proper effort underway to provide that
information in https://github.com/NixOS/nixpkgs/pull/23023.

8a928708b4 haskell: add support for Haskell Program Coverage (HPC) to the generic builder
A function is added to enable the generation of a HPC report. For example:

  pkgs.haskell.lib.doCoverage drv

will create a HPC report of the Haskell package drv in the directory:

  $out/share/hpc

Closes https://github.com/NixOS/nixpkgs/pull/22797/files.

GHC 8.0.2: use -split-sections
-split-sections replaced -split-objs with following upsides:

1) -split-objs adds considerable overhead to compile time

2) combined with stripping, it causes issues when cross-compiling

For upstream see https://ghc.haskell.org/trac/ghc/ticket/8405

This is supported only for Linux/Windows using ld linker.

GHC master also turns on -split-sections by default.

Example using stack:

Without splitting

  $ du /nix/store/5paayhibayr73zqfaj458g4k4mv108jn-stack-1.3.2
  4       /nix/store/5paayhibayr73zqfaj458g4k4mv108jn-stack-1.3.2/share/bash-completion/completions
  4       /nix/store/5paayhibayr73zqfaj458g4k4mv108jn-stack-1.3.2/share/bash-completion
  4       /nix/store/5paayhibayr73zqfaj458g4k4mv108jn-stack-1.3.2/share
  23416   /nix/store/5paayhibayr73zqfaj458g4k4mv108jn-stack-1.3.2/bin
  23420   /nix/store/5paayhibayr73zqfaj458g4k4mv108jn-stack-1.3.2

With -split-objs

  $ du /nix/store/fypymm529adpx71gdzm0851xz42wdbz0-stack-1.3.2
  20632   /nix/store/fypymm529adpx71gdzm0851xz42wdbz0-stack-1.3.2/bin
  4 /nix/store/fypymm529adpx71gdzm0851xz42wdbz0-stack-1.3.2/share/bash-completion/completions
  4 /nix/store/fypymm529adpx71gdzm0851xz42wdbz0-stack-1.3.2/share/bash-completion
  4       /nix/store/fypymm529adpx71gdzm0851xz42wdbz0-stack-1.3.2/share
  20636   /nix/store/fypymm529adpx71gdzm0851xz42wdbz0-stack-1.3.2

With -split-sections

  $ du /nix/store/40l6krinx1zx41lr87c4m12hxj4ldf3x-stack-1.3.2
  4       /nix/store/40l6krinx1zx41lr87c4m12hxj4ldf3x-stack-1.3.2/share/bash-completion/completions
  4       /nix/store/40l6krinx1zx41lr87c4m12hxj4ldf3x-stack-1.3.2/share/bash-completion
  4       /nix/store/40l6krinx1zx41lr87c4m12hxj4ldf3x-stack-1.3.2/share
  20672   /nix/store/40l6krinx1zx41lr87c4m12hxj4ldf3x-stack-1.3.2/bin
  20676   /nix/store/40l6krinx1zx41lr87c4m12hxj4ldf3x-stack-1.3.2

Note: you currently need following overrides to build stack on 802:

   vector-algorithms = dontCheck super.vector-algorithms;
   path-io = doJailbreak super.path-io;
   stack = doJailbreak super.stack;

Note: Should also work on GHC 8.0.1, but I'm being careful here.
      We could backport later on.
