Added `make -C src check-abi` target to leverage libabigail 2.0 tools to
check for ABI changes.
Add ABI baseline files for aarch64, i686, riscv, s390x, and x86_64 Linux
targets and aarch64 and x86_64 QNX SDP 7.1 targets.
Used the check-abi target in the CI-unix github workflow.
This target is no longer supported by common toolchains or operating
systems. If support is required, it can still be found in libunwind
version 1.7 and earlier.
All warnings should be heeded, including the ones spat out by autoreconf. In
this case, autoconf wanted a place to generate its m4 files into and automake
wanted the right target names in doc/Makefile.am.
Also added AM_SILENT_FILES([yes]) to reduce the visual noise in build output to
make spotting build problems easier. You can override the silent default by
running `make` with `V=0` appended to the command line.
Removed the unnecessary and unused acinclude.m4 file to reduce clutter in the
source directory.
This commit adds support for Linux on LoongArch. Only 64-bit is supported
at the moment.
The changes were tested on a LoongArch architecture Loongson-3A5000
processor (LoongArch is a new RISC ISA, which is a bit like MIPS or
RISC-V.).

When set, unwind.h won't be copied to the installation directory. Some
platforms provide their own unwind.h that might conflict with the one
supplied with libunwind
This adds a port to Linux on the IBM Z platform (a.k.a s390x). It only
supports the 64-bit ABI. Most functionality is working and all the tests
pass with the exception of the coredump tests*.
Unwinding is only supported if DWARF unwind information is present.
libunwind can't currently make use of the backchain (if present).
The getcontext/setcontext functions only preserve/restore a subset of
registers. Currently this only consists of callee-saved registers and
some parameter registers.
Vector registers and access registers are not saved (and aren't callee-
saved) by getcontext and cannot currently be modified. They will however
be restored unmodified after resuming a context from a signal handler.
There is no special libunwind support for setjmp, the functionality is
emulated using glibc (I think all the ports do this for modern Linux
kernels).
* Unwinding on s390x requires floating point register access which the
coredump library doesn't currently support.
- Add autogen.sh to bootstrap autotools generation
- Make generation of man pages optional, and check for
availibity of latex2man if documentation is requested.

Add support for the 32bit SuperH architecture running Linux.
Specifically, support is added for SH4, and support for earlier SH
versions and to the 64bit SH5 are left out. This was tested in qemu with
a little-endian SH4 debian image & GCC 4.7 cross compiler.
Use automake's '+=' to simplify include_HEADERS rules. Move most
EXTRA_DIST files to noinst_HEADERS, eliminating duplication of headers
listed by include_HEADERS. Add MIPS and PPC32 headers that were not
being distributed previously.
