If someone wants to collaborate on it, feel free to mail me. I'd be happy to help if you have any questions regarding the LDC side of things. As for the actual implementation, I guess I have to pass, even though I have a pretty good understanding of SEH right now, because I'm right in the middle of an exam session at university right now. My plan was to have a look at this in September or so, but I'll gladly work on ARM support instead. David

This only applies to Windows, which is in general pretty much uncharted territory. Once in a while, someone (including me) tries to use it for their own projects and fixes the necessary stuff, but it has never reached the »supported« status due to lack of exception support (both 32 bit/64 bit). Also note that Kai is specifically interested in building LDC using MSVC. Using MinGW, I was able to get LDC2/Phobos to work on 32 bit Windows pretty straightforwardly some time ago, but again, there is no exception support yet. David

Re: build Ldc2 for win xp 32 bit Error
Dwarf2 exceptions work in clang+gcc on win32. It would be SOME exception handling (and quite interesting, I'd say).

Is there some other patent that people are referring to? which basically means: never gonna happen. An alternative could be setjmp/longjmp. On 64bit it looks a bit better, where the correct way seems to be to use the Win64 exception ABI. Win64 SEH is scarcely any different to Win32 SEH, it's just better documented. You can do the same thing on Win32. http://clang-developers.42468.n3.nabble.com/LLVM-Clang-and-setjmp-longjmp-exception-handling-on-MinGW-td3407322.html http://msdn.microsoft.com/en-us/library/1eyas8tf.aspx The situation makes no sense to me.

Unless I'm mistaken, SEH on Win64 is quite a lot different to Win32, as it is based on tables, rather than keeping FS:[0] up to date in the function pro-/epilogues. David
