Subject: objective-c++ parsing. Turn off delayed parsing
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=39700f81c5b42e6be93be10275602915f872fc86;p=clang

objective-c++ parsing. Turn off delayed parsing
of out-of-line c++ method definition which happens
to be inside an objc class implementation
until I can figure out how to do it. This is to fix
a broken project.
