2024-11-13libstdc++: Refactor std::hash specializationsJonathan Wakely2-0/+8
This attempts to simplify and clean up our std::hash code. The primary benefit is improved diagnostics for users when they do something wrong involving std::hash or unordered containers. An additional benefit is that for the unstable ABI (--enable-symvers=gnu-versioned-namespace) we can reduce the memory footprint of several std::hash specializations. In the current design, __hash_enum is a base class of the std::hash primary template, but the partial specialization of __hash_enum for non-enum types is disabled. This means that if a user forgets to specialize std::hash for their class type (or forgets to use a custom hash function for unordered containers) they get error messages about std::__hash_enum not being constructible. This is confusing when there is no enum type involved: why should users care about __hash_enum not being constructible if they're not trying to hash enums? This change makes the std::hash primary template only derive from __hash_enum when the template argument type is an enum. Otherwise, it derives directly from a new class template, __hash_not_enabled. This new class template defines the deleted members that cause a given std::hash specialization to be a disabled specialization (as per P0513R0). Now when users try to use a disabled specialization, they get more descriptive errors that mention __hash_not_enabled instead of __hash_enum. Additionally, adjust __hash_base to remove the deprecated result_type and argument_type typedefs for C++20 and later. In the current code we use a __poison_hash base class in the std::hash specializations for std::unique_ptr, std::optional, and std::variant. The primary template of __poison_hash has deleted special members, which is used to conditionally disable the derived std::hash specialization. This can also result in confusing diagnostics, because seeing "poison" in an enabled specialization is misleading. Only some uses of __poison_hash actually "poison" anything, i.e. cause a specialization to be disabled. In other cases it's just an empty base class that does nothing. This change removes __poison_hash and changes the std::hash specializations that were using it to conditionally derive from __hash_not_enabled instead. When the std::hash specialization is enabled, there is no more __poison_hash base class. However, to preserve the ABI properties of those std::hash specializations, we need to replace __poison_hash with some other empty base class. This is needed because in the current code std::hash<std::variant<int, const int>> has two __poison_hash<int> base classes, which must have unique addresses, so sizeof(std::hash<std::variant<int, const int>>) == 2. To preserve this unfortunate property, a new __hash_empty_base class is used as a base class to re-introduce du0plicate base classes that increase the class size. For the unstable ABI we don't use __hash_empty_base so the std::hash<std::variant<T...>> specializations are always size 1, and the class hierarchy is much simpler so will compile faster. Additionally, remove the result_type and argument_type typedefs from all disabled specializations of std::hash for std::unique_ptr, std::optional, and std::variant. Those typedefs are useless for disabled specializations, and although the standard doesn't say they must *not* be present for disabled specializations, it certainly only requires them for enabled specializations. Finally, for C++20 the typedefs are also removed from enabled specializations of std::hash for std::unique_ptr, std::optional, and std::variant. libstdc++-v3/ChangeLog: * doc/xml/manual/evolution.xml: Document removal of nested types from std::hash specializations. * doc/html/manual/api.html: Regenerate. * include/bits/functional_hash.h (__hash_base): Remove deprecated nested types for C++20.

2024-11-06libstdc++: Deprecate useless <cxxx> compatibility headers for C++17Jonathan Wakely2-0/+18
These headers make no sense for C++ programs, because they either define different content to the corresponding <xxx.h> C header, or define nothing at all in namespace std. They were all deprecated in C++17, so add deprecation warnings to them, which can be disabled with -Wno-deprecated. For C++20 and later these headers are no longer in the standard at all, so compiling with _GLIBCXX_USE_DEPRECATED defined to 0 will give an error when they are included. Because #warning is non-standard before C++23 we need to use pragmas to ignore -Wc++23-extensions for the -Wsystem-headers -pedantic case. One g++ test needs adjustment because it includes <ciso646>, but that can be made conditional on the __cplusplus value without any reduction in test coverage. For the library tests, consolidate the std_c++0x_neg.cc XFAIL tests into the macros.cc test, using dg-error with a { target c++98_only } selector. This avoids having two separate test files, one for C++98 and one for everything later. Also add tests for the <xxx.h> headers to ensure that they behave as expected and don't give deprecated warnings. libstdc++-v3/ChangeLog: * doc/xml/manual/evolution.xml: Document deprecations. * doc/html/*: Regenerate. * include/c_compatibility/complex.h (_GLIBCXX_COMPLEX_H): Move include guard to start of file.

2024-10-09libstdc++: Enable _GLIBCXX_ASSERTIONS by default for -O0 [PR112808]Jonathan Wakely2-6/+22
Too many users don't know about -D_GLIBCXX_ASSERTIONS and so are missing valuable checks for C++ standard library preconditions. This change enables libstdc++ assertions by default when compiling with -O0 so that we diagnose more bugs by default. When users enable optimization we don't add the assertions by default (because they have non-zero overhead) so they still need to enable them manually. For users who really don't want the assertions even in unoptimized builds, defining _GLIBCXX_NO_ASSERTIONS will prevent them from being enabled automatically. libstdc++-v3/ChangeLog: PR libstdc++/112808 * doc/xml/manual/using.xml (_GLIBCXX_ASSERTIONS): Document implicit definition for -O0 compilation.
