From: Alexandre Oliva <aoliva@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc(refs/users/aoliva/heads/testme)] Add dg-require-wchars to libstdc++ testsuite Date: Fri, 18 Dec 2020 14:46:17 +0000 (GMT) [thread overview] Message-ID: <20201218144617.C56A2385702C@sourceware.org> (raw) https://gcc.gnu.org/g:3cf14e818ebcce936aafd149c57252496dc0737e commit 3cf14e818ebcce936aafd149c57252496dc0737e Author: Corentin Gay <gay@adacore.com> Date: Fri Dec 18 11:39:24 2020 -0300 Add dg-require-wchars to libstdc++ testsuite Some tests uses structures from the libstdc++ that are present only if the target has a wchar.h header. However, those tests do not check that the target supports those constructs before executing the tests. The function dg-require-wchars checks that "_GLIBCXX_USE_WCHAR_T" is defined by the configure of the libstdc++. If it is not the case, the test is not executed. for libstdc++-v3/ChangeLog * testsuite/lib/dg-options.exp: Add dg-require-wchars function. * testsuite/lib/libstdc++.exp: Add check_v3_target_wchars function. * testsuite/22_locale/codecvt/codecvt_utf16/79980.cc: Add requirement. * testsuite/22_locale/codecvt/codecvt_utf16/misaligned.cc: Likewise. * testsuite/22_locale/codecvt/codecvt_utf8/79980.cc: Likewise. * testsuite/22_locale/codecvt/codecvt_utf8_utf16/79511.cc: Likewise. * testsuite/22_locale/conversions/buffer/1.cc: Likewise. * testsuite/22_locale/conversions/buffer/2.cc: Likewise. * testsuite/22_locale/conversions/buffer/3.cc: Likewise. * testsuite/22_locale/conversions/buffer/requirements/typedefs.cc: Likewise. * testsuite/22_locale/conversions/string/1.cc: Likewise. * testsuite/22_locale/conversions/string/2.cc: Likewise. * testsuite/22_locale/conversions/string/3.cc: Likewise. * testsuite/22_locale/conversions/string/66441.cc: Likewise. * testsuite/22_locale/conversions/string/requirements/typedefs.cc: Likewise. * testsuite/22_locale/conversions/string/requirements/typedefs-2.cc: Likewise.
