Could you also mention that on some architectures (eg: x86_64),
libunwind uses a higher performance method where only a minimal subset
of the machine context is used for unwinding? Also, in unusual cases
where the compiler spills the minimal subset above to another
register, we fall back to the normal unwinding method which uses the
full machine state.
