To me this is an amazing accomplishment. Looking at the tables I do have one question. It shows boost build failing most tests. Doesn't bjam need to work before you can even run the tests? Robert Ramey

bjam works well enough to run all of the regression tests, but the clang module for Boost.Build isn't mature enough to pass all of the build system's tests. Frankly, I need help with this: I don't have the deep understanding of bjam needed to make it work. - Doug

I don't think you need to feel responsible for build tests at all. Some of them test pretty contrived functionality, and many depend on more on OS and user config than toolset, so any failure must be carefully analysed -- and often causes no problems for Boost itself whatsoever. - Volodya

This looks like a bug in your system headers, although Clang can work around that. Please file a Clang bug (and any further discussion should happen there or on the Clang mailing lists). - Doug

Whats the status of Windows exception handling in LLVM? (i guess that lack of exception support would cause some problems with the tests.)
That's an interesting question. Doug mentioned no exception support at BoostCon, yet I see some exception support listed in the table at http://clang.llvm.org/cxx_status.html#specification. There are no details, so it is unclear what is and isn't supported. _____ Rob Stewart robert.stewart@sig.com Software Engineer, Core Software using std::disclaimer; Susquehanna International Group, LLP http://www.sig.com IMPORTANT: The information contained in this email and/or its attachments is confidential.

Remember, the C++ status table there [1] only covers the front end, which has complete support for exceptions (modulo bugs!). However, it does not capture platform support in the back end. LLVM supports DWARF exceptions, which work on Linux, Darwin, and many other *nix systems, including (I believe) Cygwin on Windows [2]. Visual C++ uses a different exception model that isn't implemented in LLVM. The main pattern here is that the vast majority of LLVM (and Clang) developers work on Linux, Mac OS X, or FreeBSD, so those platforms are well-supported. Without more Windows developers involved in pushing LLVM and Clang forward on their platform, support for Windows will lag behind. - Doug [1] The status table itself is a bit dated; I'll fix it when time permits, but the general comment is: Everything in C++98/03 is implemented except export; file bugs if Clang is wrong. [2] As Eric mentioned, there are issues with Cygwin, too.

VC++ did move from SEH to something similar to table based unwinding, but, AFAIK it is still quite different from DWARF tables format and not compatible. -- gpd
VC's C++ exception handling on x64 is table-based but still powered by SEH. Debug into a throw and you'll see VC's _CxxThrowException() call Windows' RaiseException(). Stephan T.

I'm slowly working on getting clang to parse Microsoft's headers. Once that's done, there are still a lot of ABI issues (name mangling, exception handling, and calling conventions at least). In Christ, Steven Watanabe

The default libstdc++ 4.2 on Snow Leopard. I'd like to try it with libc++ at some point, but I suspect that I'll need to add Boost.Config support first. - Doug
