Subject: Add missing function in 20_util/exchange/1.cc.
X-Git-Tag: releases/gcc-4.9.0~3446
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=37ea0d87a36e36b706fb32491118e0da2a530099;p=thirdparty%2Fgcc.git

Add missing function in 20_util/exchange/1.cc.

When this test is compiled at -O0, the compiler does not remove the
address comparison. This causes a link failure, since the body of f()
is missing.

	* testsuite/20_util/exchange/1.cc: Add missing function
	bodies.
