Ok, I can do this for linux, at least for the rc1 phase. I am going on
vacation at the end of july.
Does llvm+clang have some automated testing infrastructure for
releases, such as buildbots pointing to the release branches?

I think having prebuilt binaries of lldb would be a good thing, as it
would make it much easier for people to try it out. I see a couple of
possible problems with this:
- clang uses configure+make to build the release version. We usually
build with cmake and I don't think anybody seriously tests the
configure build of lldb. However I guess it should be possible to make
configure work, or we can provide lldb binaries built with cmake. I
know there are some plans to deprecate the configure build, do you
have any idea what's the progress of that?
- lldb has a smaller set of supported architectures than clang. It
should build (or we can easily make it build) on the different
flavours of linux x86(_64). With some effort, it should build on
arm/aarch64/mips, but except arm, these targets are in a pretty bad
shape.
- lldb is much less stable than clang. However, since we are already
releasing it as part of 3.7, i see no reason to not provide binaries
as well.

What do you think?
