They don't. GDC and LDC use libunwind, whereas DMD uses its own 
custom EH implementation.

With GDC and LDC, you'd just need to add your code to handle 
Objective-C exceptions to the personality functions. libunwind 
exceptions have a "type"/"source language" field, and by default 
most implementations either ignore unknown exception types or 
abort on encountering them.
