Re: [libunwind] Changing the value of "gp"

[David Mosberger]

Praveen,

I realized that you can't really replace the longjmp with
unw_resume(), because you may be restarting execution at some place
other than the last call-site of a function.  The 2nd scheme I
proposed should still work, except that you'd also have to use
setjmp() in SETUP_EXC(), would raise the exception with longjmp(), and
would use libunwind only to locate the appropriate exception handler.

Of course, using a language that natively supports exception handling
might be a better choice, alltogether. ;-)
