I found __ia64_backtrace() which works for me.  From the 46MB download
ftp://ftp.cygnus.com/pub/ia64-linux/snap-001117/src.tar.gz  [3 months old]
take gcc/config/ia64/frame-ia64.c .  Also add from gcc/ :
  defaults.h  frame.h  gthr-posix.h  gthr.h  ia64.h
and finally <build-dir>/gcc/tconfig.h after configuring.

An alternative is the linux kernel 2.4.1 implementation in
include/asm-ia64/unwind.h, arch/ia64/kernel/unwind_i.h, and
arch/ia64/kernel/unwind.c which looks to be more flexible but
needs some work for use in user space.
