--- Comment #8 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Tue Aug 20 21:21:15 2019 New Revision: 274756 URL: https://gcc.gnu.org/viewcvs?rev=274756&root=gcc&view=rev Log: PR libstdc++/91371 make std::is_function handle other calling conventions The x86 attributes such as ms_abi, stdcall, fastcall etc. alter the function type, which means that functions with one of those attributes do not match any of the partial specializations of std::is_function. Rather than duplicating the list for every calling convention, use a much simpler definition of std::is_function. Also redefine __is_referenceable to not rely on partial specializations for each type of referenceable function. PR libstdc++/91371 * include/std/type_traits (is_function): Simplify definition. Remove partial specializations for function types. (__is_referenceable): Simplify definition. * testsuite/20_util/bind/91371.cc: New test. * testsuite/20_util/is_function/91371.cc: New test. * testsuite/20_util/is_function/value.cc: Check more pointer types. * testsuite/20_util/is_member_function_pointer/91371.cc: New test. * testsuite/20_util/is_object/91371.cc: New test.
