Subject: With the introduction of nullptr, a template argument that refers to a declaration... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=92d5077d35cb4ac7e3fdb5785fc4e843e9fffdc8;p=clang

With the introduction of nullptr, a template argument that refers to a declaration can now be NULL. Use cast_or_null appropriately
