e09f9701ff Handle register nums > 16 on x86_64 
gcc generates them when using ms-abi. Support disabled by
default since it increases the cache footprint of the library.

e003e44a37 Check for <sys/ptrace.h> before including it 
On ia64-hpux version 11.31, <sys/ptrace.h> has been removed.
This patch adds a configure check for this header file, and only
includes <sys/ptrace.h> if it exists.

ce847afb3b Build ELF convenience libraries 
Rather than building the sources directly, create a library that
gets linked statically into libunwind.la and libunwind-$(arch).la.

717239a936 Conditionalize -static-libcxa test 
The -static-libcxa test only applies for the Intel compiler, but the
check could pass for some versions of GCC.  It would be accepted with
a warning in the past, but it produces an error with GCC 4.6.

3ac945b7ee Improve debug-frame configure option default 
Ensure that --enable-debug-frame is set automatically when building
libunwind for an ARM target.  Other targets continue to have
--disable-debug-frame as the default setting.

574873ca6e Improve configure check reporting. 
Adds numerous AC_MSG_CHECKING and AC_MSG_RESULT pairings for
configuration tests that were previously unreported.  Relocates
the debug configuration to the same part of the file as the command
line option declaration for associative clarity.  Makes it easier
to confirm the resultant configuration matches original intentions.

045c55b2a2 Be conservative in all pointer derefrences by default. 
Since most people can't completely control their compile or runtime
environment, it becomes hard to ensure that unwind data is perfect.

2fce54102c Implement _Unwind_GetIPInfo() as required by the C++ ABI 
Provide a special implementation for ia64, because the unwind
information is such that an IP adjustment is not necessary before
looking up unwind info.

Bad things happen if libunwind only provides parts of the ABI and
the rest come from libgcc.

a2c27a4ab7 Make .debug_frame support optional. 
Because these code paths use malloc and stdio, they could
cause deadlocks when we try to unwind stack from inside malloc.
