Subject: Teach code completion not to include out-of-line declarations and
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9b0ba87a5ee4d872ae60dbfe4cbd500e57b8a775;p=clang

Teach code completion not to include out-of-line declarations and
definitions in its results. The original declarations will be visible
wherever they are declared.
