 1.11  04-Feb-2019  mrg use __builtin_unreachable() after calls that panic or switch context
 1.10  17-Jul-2018  joerg The semantics of DW_CFA_GNU_args_size have changed subtile over the
years. Adopt the new convention that it is call-site specific and that
it should be applied before moving the IP by personality routines, but
not during normal unwinding. Further discussion can be found in
LLVM's phabricator review D38680.
 1.9  17-Feb-2015  joerg branches: 1.9.16; 1.9.18;
Provide _Unwind_Find_FDE for libgcc_s compatibility.
 1.8  13-Apr-2014  joerg branches: 1.8.2; 1.8.4; 1.8.8; 1.8.10;
Move definition of what the native register layout is into
Registers.hpp.
 1.7  02-Apr-2014  joerg branches: 1.7.2;
Support SH3 in our unwinder.
 1.6  24-Mar-2014  joerg Add m68k support to our unwinder.
 1.5  20-Mar-2014  joerg Fix DW_CFA_GNU_args_size handling. The primary architecture using this
opcode is VAX. A function call pushes the number of arguments given onto
the stack and "ret" will pop it automatically. The FDE of the caller
contains the amount of stack space used for arguments (and possibly
extra padding), so unwinding has to compensate for this when "returning"
from a function. This is exactly the case when step() is done. The
existing handling in _Unwind_SetIP no longer makes sense.
 1.4  18-Mar-2014  joerg Add basic unwind support for VAX. PSW handling and stack pointer after
resume is still incomplete.
 1.3  13-Mar-2014  joerg Add _Unwind_GetIPInfo for libstdc++.
 1.2  29-Jan-2014  matt Add support for non-EABI (DWARF) ARM exception handling.
 1.1  14-Oct-2013  joerg Add a heavily modified version of Apple's libunwind as released under
MIT license in libc++abi. At the moment, only x86 support is tested.

 1.8.8.3  03-Dec-2017  jdolecek update from HEAD
