As you may remember from #140774, GHC on aarch64-darwin can't properly eliminate dead code, leading to a lot of references if Paths_ modules are involved that may not be necessary.

A common case is that binaries that depend on other libraries that use a Paths_ module will incur a reference on that library's out path despite being statically linked against the library (even though the reference itself is dead code). On other platforms (even x86_64-darwin) GHC is able to eliminate such references, but not on aarch64-darwin. For such packages, justStaticExecutables is practically useless since GHC is pulled in transitively.

@9999years has contributed an extra check to justStaticExecutables which prevents this scenario (#304352). As a consequence, a few packages are broken on aarch64-darwin. In the interest of landing the bundled changes from haskell-updates soon, I'll disable justStaticExecutables for the following packages on aarch64-darwin since it wasn't doing much anyways:

• bench @Gabriella439
• hadolint
• haskell-ci
• hci @roberth
• hercules-ci-agent @roberth
• matterhorn
• nix-serve-ng
• oama @aidalgol
• hledger-web @maralorn
• shake @ncfavier
• stack @cdepillabout
• emanote (effective on all platforms since the reference was present everywhere) @srid

This will take effect when #315167 is merged.

Maintainers are encouraged to submit a workaround for the issue on aarch64-darwin via remove-references-to (which seems to be the only solution at the moment) and to reenable justStaticExecutables. Examples for such fixes are:

• 2901eb8
• caa1c96

Please make sure these fixes are conditional to aarch64-darwin.
