Subject: When computing the canonical profile of a DeclRefExpr or MemberExpr,
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=218f47ff746b2216e949e79a287c034fd0bd8713;p=clang

When computing the canonical profile of a DeclRefExpr or MemberExpr,
don't include the nested-name-specifier or template arguments: they
were only relevant when resolving the declaration. Fixes PR7460.
