1# ARM-SPECIFIC OVERRIDES FOR THE HASKELL PACKAGE SET IN NIXPKGS
2#
3# This extension is applied to all haskell package sets in nixpkgs if
4# `stdenv.hostPlatform.isAarch` to apply arm specific workarounds or
5# fixes.
6#
7# The file is split into three parts:
8#
9# * Overrides that are applied for all arm platforms
10# * Overrides for aarch32 platforms
11# * Overrides for aarch64 platforms
12#
13# This may be extended in the future to also include compiler-
14# specific sections as compiler and linker related bugs may
15# get fixed subsequently.
16#
17# When adding new overrides, try to research which section they
18# belong into. Most likely we'll be favouring aarch64 overrides
19# in practice since that is the only platform we can test on
20# Hydra. Also take care to group overrides by the issue they
21# solve, so refactors and updates to this file are less tedious.
