I've played with exception handling for cegcc on ARM. The second link is
interesting, I had never read this article but it describes what I did.
On the ARM compilers, you can say
int func(int n)
__attribute__((__exception_handler__(crash)));
to declare that crash is the exception handler for func. It does this by
putting the address of crash in the pdata structure for func.
I also have code for a __dft_exception_handler__ attribute that might
work similar to the SetUnhandledExceptionFilter from your other mail.
This needs to be ported to x86 though (it does a bit of assembler which
is obviously different). This code didn't interfere with anything for
ARM, whether that's true for x86 is unknown to me.
