mostang.com!davidm ed67c3edb7 (ia64_pregnum): Rename IA64_REG_RP to IA64_REG_IP. 
(ia64_loc_t): New type.  For UNW_LOCAL_ONLY, it's a single word, as before.
	For the generic case, it's a 2-word structure.  This provides enough
	space to encode all necessary info both for 32-bit targets (which require
	only 4-byte aligned addresses) and for targets which are limited to
	accessing ucontext_t values via uc_access(3).
(ABI_MARKER_LINUX_SIGTRAMP): New macro.
(ABI_MARKER_HP_UX_SIGTRAMP): New macro.
(struct cursor): Consolidate bsp_loc, bspstore_loc, pfs_loc, rnat_loc, ip_loc,
	pri_unat_loc, unat_loc, pr_loc, lc_loc, fpsr_loc, r4-r7_loc,
	b1-b5_loc, f2-f7_loc, and fr_loc[] into loc[] array.  Note that
	there is now a separate PSP-loc (loc[IA64_REG_PSP]) in addition
	to the cached psp value.
	Rename sigcontext_loc to sigcontext_addr.
	Remove is_signal_frame memeber and add abi_marker member instead.
	Change type of rbs_area[].rnat_loc to ia64_loc_t.
(struct ia64_global_unwind_state): Remove preg_index[] array.

README 

-*- mode: Outline -*-

This is version 0.92 of the unwind library.  At the moment, only the
IA-64 Linux (IPF Linux) platform is fully supported.  Some very basic
support for x86 exists also.  However, the x86 support is based purely
on the frame-chain and does not use unwind information, so its utility
is limited.

* General Build Instructions

In general, this library can be built and installed with the following
commands:

	$ ./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.

* Building with Intel ECC

To build libunwind with the Intel Electron compiler (ECC), it is
recommended to run configure like this:

	$ ./configure CC=ecc CXX=ecc CCAS=gcc

The reason for this is that ECC uses the Intel assembler, which
doesn't grok some of the IA-64 assembly code in the "tests" directory.

For an ECC-built version of libunwind to work properly, you also need
to ensure that /usr/include/asm/fpu.h contains a "long double" member
called "__dummy" in the declaration of "struct ia64_fpreg".  Without
that member, variables of type unw_context_t won't be aligned
properly.

* Building on HP-UX

For the time being, libunwind must be built with GCC on HP-UX.
Unfortunately, gcc-3.0 ships with a bad version of sys/types.h.
The workaround for this is:

    $ mkdir $top_dir/include/sys
    $ cp /usr/include/sys/types.h $top_dir/include/sys

* Regression Testing

After building the library, you can run a set of regression tests with:

	$ make check

Unless you have a very recent library and compiler installed, it is
currently expected to have the following tests fail:

	Gtest-init		(should work with glibc-2.3.1)
	Ltest-init		(should work with glibc-2.3.1)
	test-ptrace		(should work with glibc-2.3.1)
	run-ia64-test-dyn1	(should work with glibc-2.3.1)
