MinGW - Minimalist GNU for Windows

Hi all.

I have prepared a snapshot release of GCC with support for
structured exception handling. You can get it here if you are
interrested:

http://reactos.wox.org/download.php?id=30 (i386 binary)
http://reactos.wox.org/download.php?id=31 (source)
http://reactos.wox.org/download.php?id=32 (diff)

Can I post an announcement on the mingw-users mailing list?


In winbase.h of w32api, these are defined:

#define EXCEPTION_EXECUTE_HANDLER		1
#define EXCEPTION_CONTINUE_SEARCH		0
#define EXCEPTION_CONTINUE_EXECUTION	(-1)

In MSVC they are defined in excpt.h. Should we move them?

I would like to put these two macros in excpt.h too:

#define GetExceptionInformation() \
  ((LPEXCEPTION_POINTERS)__builtin_get_exception_information())

#define GetExceptionCode() \
  ((DWORD)__builtin_get_exception_code())

Is this acceptable?

No, I have only tested it with the C compiler. I haven't tested it with the C++ compiler since I'm unable to build libstdc++-v3. It will need more work in order to get it to work parallel to the C++ exception handling.

See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/_core_exception_handling_topics_.28.seh.29.asp for the interesting discussion, especially the NOTE.

Watch for linebreaks in the URL. Earnie. IIRC, in MSVC, SEH is integrated in C++ exception handling, ie. SEH exceptions are translated into C++ exceptions. Casper Hornstrup

Although it can be used with C++ it is most definitely suggested not to do so, on every page discussing SEH I've seen thus far. The warning isn't a small blurb hidden in some obtuse corner, there's a large paragraph about it, on every page. I'll take a look again tomorrow. Earnie.

Ideally, they same would happen in Ada, ie. SEH exceptions being translated into Ada exceptions. -- -- Jerry van Dijk | email: jvandyk@... -- Leiden, Holland | web: users.ncrvnet.nl/gmvdijk
