Subject: Wdeprecated: Make Filter safely move constructible.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7f83e701f4a48112ba41e981a49febfc1a8423c1;p=clang

Wdeprecated: Make Filter safely move constructible.

makeFilter returns Filters by value which seems to be only safe when the
copy doesn't occur and RVO kicks in. Make the object safely movable to
support this more reliably.
