Subject: libstdc++: Adjust flat_set::swap swapping order
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=f052dcf8699fa650cda20944fdd3a96104b6830c;p=thirdparty%2Fgcc.git

libstdc++: Adjust flat_set::swap swapping order

In r17-908 I accidentally made us swap the comparator first, but we
decided that the container should be swapped first.

libstdc++-v3/ChangeLog:

	* include/std/flat_set (_Flat_set_impl::swap): Swap _M_cont
	first.
