2018-03-14PR libstdc++/78420 Make std::less etc. yield total order for pointersJonathan Wakely3-18/+478
In order for std::less<T*> etc. to meet the total order requirements of [comparisons] p2 we need to cast unrelated pointers to uintptr_t before comparing them. Those casts aren't allowed in constant expressions, so only cast when __builtin_constant_p says the result of the comparison is not a compile-time constant (because the arguments are not constants, or the result of the comparison is unspecified). When the result is constant just compare the pointers directly without casting. This ensures that the function can be called in constant expressions with suitable arguments, but still yields a total order even for otherwise unspecified pointer comparisons. For std::less<void> etc. add new overloads for pointers, which use std::less<common_type_t<T*,U*>> directly. Also change the generic overloads to detect when the comparison would call a built-in relational operator with pointer operands, and dispatch that case to the corresponding specialization for void pointers. PR libstdc++/78420 * include/bits/stl_function.h (greater<_Tp*>, less<_Tp*>) (greater_equal<_Tp*>, less_equal<_Tp>*): Add partial specializations to ensure total order for pointers. (greater<void>, less<void>, greater_equal<void>, less_equal<void>): Add operator() overloads for pointer arguments and make generic overloads dispatch to new _S_cmp functions when comparisons would use built-in operators for pointers. * testsuite/20_util/function_objects/comparisons_pointer.cc: New.

2018-03-09Use non-throwing is_directory in filesystem::create_directoryJonathan Wakely3-6/+7
The create_dir helper was calling the throwing form of filesystem::is_directory instead of passing the error_code argument. Since std::filesystem::create_directory(const path&, error_code&) is noexcept, it would call std::terminate if an error occurred in is_directory. Passing the error_code also takes care of clearing it in the case where is_directory returns true. src/filesystem/ops.cc (create_dir): Pass error_code to is_directory. src/filesystem/std-ops.cc (create_dir): Likewise.
