This is version 0.95 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.
support for x86 and HP-UX/IPF exists also. However, the x86 support
is based purely on the frame-chain and does not use unwind
information, so its utility is limited. Similarly, the HP-UX/IPF
support is incomplete, though it is sufficient to do a basic
backtrace. unw_resume() is not supported, however.

that member, variables of type unw_context_t won't be aligned

** Version 8 and later
Starting with version 8, the preferred name for the IA-64 Intel
compiler is "icc" (same name as on x86). Thus, the configure-line
should look like this:
$ ./configure CC=icc CXX=icc CCAS=gcc
* 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:
Unfortunately, gcc-3.0 and gcc-3.2 ship 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
Apart from this glitch, libunwind should configure and install on
HP-UX like this:
$ ./configure CFLAGS="-g -O2 -mlp64"
Caveat: Unwinding of 32-bit (ILP32) binaries is not supported
at the moment.
* Regression Testing
After building the library, you can run a set of regression tests with:
$ make check

** Expected results on x86 Linux
The following tests are expected to fail on x86 Linux:
test-proc-info (x86 unwinder doesn't use unwind-info yet)
Gtest-exc (unw_resume() not implmented yet)
Ltest-exc (unw_resume() not implmented yet)
test-setjmp (unw_resume() not implmented yet)
** Expected results on HP-UX
"make check" is currently unsupported for HP-UX. The only test
programs that are known to work at this time are tests/bt (which
produces various backtraces) and tests/Gperf-simple, which does some
simple performance measurements.
