Jonathan Wakely e627a941dc libstdc++: Make _GLIBCXX_NODISCARD work for C++11 and C++14 ... The _GLIBCXX_NODISCARD macro only expands to [[__nodiscard__]] for C++17 and later, but all supported compilers will allow us to use that for C++11 and C++14 too. Enable it for those older standards, to give improved diagnostics for users of those older standards. libstdc++-v3/ChangeLog: * include/bits/c++config (_GLIBCXX_NODISCARD): Expand for C++11 and C++14. * testsuite/22_locale/locale/cons/12438.cc: Adjust dg-warning to expect nodiscard warnings for C++11 and C++14 as well. * testsuite/22_locale/locale/operations/2.cc: Likewise. * testsuite/25_algorithms/equal/debug/1_neg.cc: Likewise. * testsuite/25_algorithms/equal/debug/2_neg.cc: Likewise. * testsuite/25_algorithms/equal/debug/3_neg.cc: Likewise. * testsuite/25_algorithms/find_first_of/concept_check_1.cc: Likewise. * testsuite/25_algorithms/is_permutation/2.cc: Likewise. * testsuite/25_algorithms/lexicographical_compare/71545.cc: Likewise. * testsuite/25_algorithms/lower_bound/33613.cc: Likewise. * testsuite/25_algorithms/lower_bound/debug/irreflexive.cc: Likewise. * testsuite/25_algorithms/lower_bound/debug/partitioned_neg.cc: Likewise. * testsuite/25_algorithms/lower_bound/debug/partitioned_pred_neg.cc: Likewise. * testsuite/25_algorithms/minmax/3.cc: Likewise. * testsuite/25_algorithms/search/78346.cc: Likewise. * testsuite/25_algorithms/search_n/58358.cc: Likewise. * testsuite/25_algorithms/unique/1.cc: Likewise. * testsuite/25_algorithms/unique/11480.cc: Likewise. * testsuite/25_algorithms/upper_bound/33613.cc: Likewise. * testsuite/25_algorithms/upper_bound/debug/partitioned_neg.cc: Likewise. * testsuite/25_algorithms/upper_bound/debug/partitioned_pred_neg.cc: Likewise. * testsuite/27_io/ios_base/types/fmtflags/bitmask_operators.cc: Likewise. * testsuite/27_io/ios_base/types/iostate/bitmask_operators.cc: Likewise. * testsuite/27_io/ios_base/types/openmode/bitmask_operators.cc: Likewise. * testsuite/ext/concept_checks.cc: Likewise. * testsuite/ext/is_heap/47709.cc: Likewise. * testsuite/ext/is_sorted/cxx0x.cc: Likewise.		2024-11-14 17:00:40 +00:00
