The unwinder only has info for restoring registers.

See the C++ ABI for information on how to use the unwinder for exception
This ABI is designed for a compiler emitting code.  You need to set up
tables and call special functions.  It may be difficult to do this in a
compiler that emits C code.

Since your target is gcc, it might be easier to emit C code that uses
gcc features.  Gcc has a cleanup function attribute as of two days ago
that can be used for destructors for local variables.  If you need catch
handlers though, you could try emitting C++ code instead of C code.
