README 

This is version 0.2 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/libunwind.h and include/libunwind-ia64.h.  Finally, the test
program in 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
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:

	$ ./configure
	$ make
	$ make install prefix=PREFIX

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