[gentoo-musl] [GSoC] native-clang: daily report 07/05

[Lei Zhang]

Plan for today:
- modify libc++'s ebuild and add support for libunwind

Progress:
- write an ebuild for libunwind; unlike libc++abi, libunwind could be
installed independently
- modify libc++'s ebuild to support libc++abi and libunwind; these two
are orthogonal and can be enabled by USE flags "libcxxabi" and
"libunwind" respectively

Plan for tomorrow:
- these ebuilds don't work on musl yet; fix them

A few notes:
- There's already a package named "libunwind" under sys-libs. To avoid
conflict, I name LLVM's "llvm-libunwind". Suggestions for a better
name are welcome.
- My previous patches to clang/LLVM which add support for musl are
still in the trunk, and probably available only after version 3.9. In
my ebuilds, should I fetch source from the trunk or instead stick with
version 3.8 and maintain a set of downstream patches?

Unfortunately some features I took for granted are also absent in
version 3.8, e.g. using libc++ instead of libstdc++ as the default. If
sticking with 3.8, I'd have to make patches for these features too :(

Is it acceptable to build packages using under-development source?
What about dubbing it 3.8.0-r200 or something?

Ok, I see some scripts taking snapshots and ebuilds referring to
"mirror://gentoo/${V}.*". If I get it right, the snapshots are stored
on a server; then how do I upload my snapshots to the server?

OTOH, there're some downstream patches for llvm-3.8. How should I deal
with them? They probably can't be directly applied to the trunk
version.

Could you please do it now? I need to test my ebuild.

The script is attached. Thanks :)
