This reverts commit a27bc8b3174fa1847b5ca9f85d921c3e472cbeb1. 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.
This reverts commit c153036525575d046fc808a4805d023e3e2e9e75. Please don't add

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.
-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

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.
This reverts commit 19e2e7290a25819bd66a94db389e7e0d268f7fc0.
See the correct fix in aa64994b48a29ea8d12323942f1743fa4133527a
General purpose solution will be once we implement
https://github.com/NixOS/nixpkgs/issues/21624
This fix doesn't actually fix the cabal bug (see #16357), but it does
cause other bugs (see #20476)

This reverts commit b89fa5fd5cc3e7d27fb87bc792fe0d6553aec28d, reversing
changes made to e4b146b0417762c461c7f90f587dc82e8524f796.
This reverts commit ec8b81615462625338d76f002d92accd6eb4cf6a. The change told
the Cabal build system to use the hash-part of $out as the internal identifier
for the library it's building (rather than generating such an ID itself). While
a good idea in theory, this choice had an unfortunate side-effect: When Cabal
links libraries X, Y, and Z into an executable, then the generated binary
contains their respective IDs. Now, Nix finds those strings and treats them as
an indication that there is a *run-time dependency* on the corresponding store
paths. This means that the generated executable will always depend on the store
paths of all the Haskell libraries that went into it, even when linked
statically.
This commit fixes a problem that occurs with externally linked haskell
libraries on Darwin. It does this by adding the libraries to the
--extra-lib-dirs flag and the DYLD_LIBRARY_PATH environment variable.
Without this patch, attempts to install at least some of the packages
that start to use setupHaskellDepends (mostly gtk-related packages)
results in collisions:
building path(s) ‘/nix/store/63k5smns43f5r2ad8wcc242x0gwd70m3-ghc-8.0.1’
collision between `/nix/store/k18i1nm5hgnb82y9w2g9hmlwhk3szjld-ghc-8.0.1/lib/ghc-8.0.1/Cabal-1.24.0.0/Distribution/Compat/Binary.dyn_hi' and `/nix/store/0rwhbwsg9kmywgbrib2bs29p2hmi80za-Cabal-1.24.0.0/lib/ghc-8.0.1/Cabal-1.24.0.0/Distribution/Compat/Binary.dyn_hi'
builder for ‘/nix/store/vrjkfpm8sb96m9i5k74h8vn0rwddgy4v-ghc-8.0.1.drv’ failed with exit code 25
This would appear to me to be a consequence of setupHaskellDepends
entries being added to propagateBuildInputs. It is sufficient in the
cases I'm familiar with (taffyBar), and I think correct, to simply add
it to the otherBuildInputs.
hydraPlatforms now defaults to the value of meta.platforms rather than
defaulting to ghc.meta.hydraPlatforms. This solution is, in fact, still
sub-optimal. See https://github.com/NixOS/nixpkgs/issues/9608 for further
details.
