llvm dev - Jan 2010 - [LLVMdev] Exception Implementation Example added to Wiki

I just added an exception example to the wiki intended to be run in a JIT
environment. Although this information is heavily date dependent,
as the LLVM exception subsystem will be modified as time goes on, I could have
used such an example when I was looking into this; hence the submission.
Having said this, I'm not an LLVM expert, and even though the code works,
I'm sure there are omissions and inaccuracies, so if the experts have
the time ...

Hopefully some members of the community will find this beneficial

PS: Is there a better to upload source to the wiki than merely pasting it in?
Only image file types seemed to be allowed for upload.

Oh I could definitely use an example like that, would be very nice if
there was such an example as an included project in LLVM itself like
the other examples and tutorials, would force it to stay updated too.

EDIT:  Er, helps if I send to the LLVM list...

If the powers at be want this, I could easily transform the source to the LLVM
coding standards, and add
the necessary portable UNIX support--someone else would have to add non-UNIX
support although the
System library probably helps with this. However I'm guessing the LLVM
release flux of the exception system,
along with a lack of universal platform, dwarf JIT support might be a hinderance
in such an endeavor. I don't
know what the current platform boundaries are for either JIT or JIT with dwarf
emission, but I do know that
the LLVM exception design is being reconsidered for future releases (possibly
2.7?).

Also, as noted in the wiki, please see:

http://code.google.com/p/tart/ and 
http://www.incasoftware.de/~kamm/projects/index.php/2008/08/19/exception-handling-in-llvmdc-using-llvm/

for real world implementations. There are many others, as can be seen in the
LLVM project page.
