[cfe-dev] Status of SEH?

I would obviously like clang SEH to be compatible with my client side SEH implementation for MSVC so they can share code. I do agree that some of the MSVC implementation seems overly convoluted. Either way keep me in the loop. I should have a reasonably complete SEH client library that works when built with MSVC and builds with clang online within the next 10 days as part of the QOR project Strata-1.

not by default but as an option if its needed to get closer to
full interop with vstudio compiled libs
see Reid Kleckner talk "Bringing clang and LLVM to Visual C++ users"
