Subject: Only qualify function as constexpr for C++14 and later
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=927d1cbf75e83748def42eb1de13a43c3fe157c8;p=thirdparty%2Fgcc.git

Only qualify function as constexpr for C++14 and later

This helper function is not a valid constexpr function in C++11, so
should only be marked constexpr for C++14 and later.

	* include/debug/helper_functions.h (__valid_range): Change
	_GLIBCXX_CONSTEXPR to _GLIBCXX14_CONSTEXPR.
