I think you are confusing between the debug info and the method used
to pass exceptions across shared libraries.  The latter indeed cannot
use DWARF unwinders, but this issue is of no importance to us in this
context.

The DWARF debug info is certainly supported on x86_64.  It's even the
default, but -gdwarf-4 makes GCC use more recent version of the DWARF
standard, that produces more elaborate debug information.
