Re: backtrace() vs. _Unwind_Backtrace()

While debugging another problem, I noticed that libjava currently
attempts to use libc's backtrace() function to create a stack trace
(libjava/gnu/gcj/runtime/natStackTrace.cc).  Recently, libgcc got an
_Unwind_Backtrace() function, which I think should do exactly what's
needed there (in combination with _Unwind_GetIP()), so I think it
would make sense to switch to _Unwind_Backtrace() instead.

Hi David,

I have been working on a patch that revamps libgcj's stack tracing, using the libgcc unwinder. I should be able to post it this weekend.

One outstanding issue is what to do about Windows, which apparantly doesn't use the DWARF unwinder.

Regards

Bryce.
