[libunwind] libunwind v0.92 released

[David Mosberger]

OK, I just uploaded v0.92 to:

        ftp://ftp.hpl.hp.com/pub/linux-ia64/libunwind-0.92.tar.gz

I hope to have included fixes for the bugs that have been pointed out
since 0.91 came out.  If I missed something, please re-send a bug
report (and accept my apologies...).

This version should build both on ia64 (gcc and ecc) and x86 (only gcc
has been tested).  If you do "make test" you should expect to see the
following results:

 ia64, debian/stable, libc 2.2.5, gcc 2.96:     4 out of 15 tests failed
 ia64, debian/unstable, libc 2.3.1, gcc 3.2.3:  3 out of 15 tests failed
 ia64, debian/unstable, libc 2.3.1, ecc 7.0:    5 out of 15 tests failed
 i386, debian/stable, libc 2.2.5, gcc 2.95.4:   5 out of 10 tests failed

Based on these results, it may look like i386 works almost as well as
ia64, but that's not really true: on i386, the unwinding is still
limited to following the frame-pointer and therefore won't work on
code compiled with -fno-frame-pointer and some of the more interesting
things in libunwind, such as unw_resume() and longjmp(), simply can't
work until the i386 version takes advantage of the DWARF2 unwind info
(when available).  If anyone is interested in working on this, let me
know. ;-)

On ia64, if you get a bleeding-edge libc and gcc, libunwind does pass
all tests now.

Enjoy,
