Subject: Member function templates (and instantiations/specializations thereof)
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=77da3f4815069dbd029823edb072425551143cb1;p=clang

Member function templates (and instantiations/specializations thereof)
are never copy constructors or copy assignment operators.
