GCC Exception Handling

[David Chisnall]

Hi Everyone,

I'm currently working on adding exception handling support to clang,  
but coming across some problems trying to understand the (completely  
undocumented) ABI.  It isn't quite the same as the NeXT/Apple ABI, so  
I am wondering if anyone has any documentation about how it is  
supposed to work?

In particular, the type table needs to be populated with pointers to  
classes for selecting the correct landing pad.  I am currently unsure  
how these are meant to be found.  If anyone knows how this is supposed  
to work, please let me know.

David
