Subject: The ObjC++-to-C++ personality trick is only necessary on NeXT runtimes,
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=70cd619e74306b1599d5579e6fd6a14bd9592281;p=clang

The ObjC++-to-C++ personality trick is only necessary on NeXT runtimes,
which is not coincidentally the only place it works, either (because
of how it tests for EH_TYPE symbols).
