(none)!davidm 5cdb197f44 (unw_init_remote): Rename from ia64_init_remote(). Initialize 
cfm_loc with UNW_IA64_CFM.  Initialize bspstore_loc with
	UNW_IA64_AR_BSPSTORE.  Renamem rp_loc to ip_loc and initialize
	with UNW_IA64_IP.  Initialized the cached values of
	PR and IP.  Initialize sp and psp to value in UNW_IA64_SP.
	Initialize exception handling args by reading the corresponding
	scratch registers (r15-r18).  If the read fails, initialize
	with 0.  Finish by calling ia64_get_proc_info() instead of
	ia64_get_frame_state().

README 

This is version 0.0 of the unwind library.  At the moment, only the
IA-64 Linux (IPF Linux) platform is supported and even that support
has received only light testing.  Consequently, this release is
intended primarily to expose the unwind API to more developers and to
collect feedback on what does and does not work.  Having said that,
backtracing through gcc-generated code might work reasonably well.

There is virtually no documentation at the moment.  A brief outline of
the unwind API is in file NOTES.  To get a feel for how things are
intended to work, you may also want to take a look at include/unwind.h
and include/unwind-ia64.h.  Finally, the test program in
src/tests/bt.c shows two ways of how to do a simple backtrace: one
uses libunwind directly, the other uses a libunwind-based
implementation of the backtrace() function.  The test program in
src/tests/exc.c shows the basics of how to do exception handling with
this library.

The following steps should be used to compile and install this library:

	$ cd src
	$ make dep
	$ make
	$ make install prefix=PREFIX

where PREFIX is the installation prefix.  By default, a prefix of /usr
is used, such that libunwind.a is installed in /usr/lib and unwind.h
is installed in /usr/include.  For testing, you may want to use a
prefix of /usr/local instead.
