Subject: [PATCH] libstdc++-v3 Skip tests on Darwin8-10.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

These earlier Darwin versions have “FP_≈” inside a
comment in architecture/{ppc,i386}/math.h, which is
included by math.h which causes the tests to fail.

The intent of the tests (i.e. to ensure that the
library itself does not emit non-ascii) is covered
by other platforms, including later Darwin editions.

2019-04-21  Iain Sandoe  <iain@sandoe.co.uk>

	* testsuite/17_intro/headers/c++1998/charset.cc: Skip for Darwin8
	to Darwin10.
	* testsuite/17_intro/headers/c++2011/charset.cc: Likewise.
	* testsuite/17_intro/headers/c++2014/charset.cc: Likewise.
	* testsuite/17_intro/headers/c++2017/charset.cc: Likewise.
	* testsuite/17_intro/headers/c++2020/charset.cc: Likewise.
