llvm dev - Nov 2015 - [cfe-dev] [RFC][libcxx] Fix and maintain the no-exceptions build of libcxx

You got me there!

I think it's OK to be consistent across all the places and call abort(),
this is what I've been doing
in my current patch. I will double check this behavior with other compilers that
provide similar
functionality.

Thanks.

I also want to point out that if you really want no exceptions, you're
going to have to produce (and link to) a custom dylib; since the stuff in
the dylib *will* throw.

IIUC, what you mean here is that it's not just the libcxx headers that I
need to modify, but also the library code (stuff inside libcxx/src). This
is exactly what I'm currently working on.

I have a patch in review at http://reviews.llvm.org/D14292 which makes it
possible to get this library (.so) to build.

In my follow-up patch (which fixes some test failures on this new libcxx
library build), there are changes to both the headers as well as the core
library sources.

Thanks.
