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

[Lei Zhang <zhanglei.april@gmail.com>]

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?
