Upstream Alpine Linux distribution patches
Alpine Linux has a variety of patches to allow GHC to build against the musl libc implementation. Let's get these upstream.
Here is my take on the patches:
-
0000-alpine.patch: This is a no-brainer. Merged as 9ae24bb6. -
0000-bootstrap.patch: I really don't know about this one. The motivation is quite unclear. Needs discussion. -
0001-rm-ghc-pwd.patch: Already merged in 4c56ad36. -
0002-Correct-issue-with-libffi-and-glibc.patch: This is, unfortunately, alibffifix, not a GHC fix. I'm not enthusiastic about patching libffi like this. However,libffi's upstream is quite unresponsive and we are waiting for them to act on a number of issues, so perhaps we'll need to reconsider this. I've created #14056 (closed) to track this. -
0003-do-not-use-SHELL.patch: Looks reasonable to me. Merged as a10c2e6e. -
0004-reproducible-tmp-names.patch: Seems plausible. -
0005-buildpath-abi-stability.patch: There's some discussion in #10424. -
0006-fix-madvise.patch: Merged in 6576bf83. See #12865 (closed) -
0007-build-hp2ps-twice.patch,0008-build-unlit-twice.patch: Why?
