2019-05-31PR libstdc++/90682 allow set_terminate(0) and set_unexpected(0)Jonathan Wakely6-15/+171
Make these functions restore the default handlers when passed a null pointer. This is consistent with std::pmr::set_default_resource(0), and also matches the current behaviour of libc++. In order to avoid duplicating the preprocessor condition from eh_term_handler.cc more that into a new eh_term_handler.h header and define a macro that can be used in both eh_term_handler.cc and eh_terminate.cc.

2019-05-31Remove using-declarations that add std names to __gnu_cxxJonathan Wakely15-405/+413
These using-declarations appear to have been added for simplicity when moving the non-standard extensions from namespace std to namespace __gnu_cxx. Dumping all these names into namespace __gnu_cxx allows unportable uses like __gnu_cxx::size_t and __gnu_cxx::pair, which serve no useful purpose. This patch removes most of the using-declarations from namespace scope, then either qualifies names as needed or adds using-declarations at block scope or typedefs at class scope. * include/backward/hashtable.h (size_t, ptrdiff_t) (forward_iterator_tag, input_iterator_tag, _Construct, _Destroy) (distance, vector, pair, __iterator_category): Remove using-declarations that add these names to namespace __gnu_cxx. * include/ext/bitmap_allocator.h (size_t, ptrdiff_t): Likewise. * include/ext/debug_allocator.h (size_t): Likewise. * include/ext/functional (size_t, unary_function, binary_function) (mem_fun1_t, const_mem_fun1_t, mem_fun1_ref_t, const_mem_fun1_ref_t): Likewise. * include/ext/malloc_allocator.h (size_t, ptrdiff_t): Likewise. * include/ext/memory (ptrdiff_t, pair, __iterator_category): Likewise. * include/ext/mt_allocator.h (size_t, ptrdiff_t): Likewise. * include/ext/new_allocator.h (size_t, ptrdiff_t): Likewise. * include/ext/numeric (iota): Fix outdated comment. * include/ext/pool_allocator.h (size_t, ptrdiff_t): Likewise. * include/ext/rb_tree (_Rb_tree, allocator): Likewise. * include/ext/rope (size_t, ptrdiff_t, allocator, _Destroy): Likewise. * include/ext/ropeimpl.h (size_t, printf, basic_ostream) (__throw_length_error, _Destroy, std::__uninitialized_fill_n_a): Likewise. * include/ext/slist (size_t, ptrdiff_t, _Construct, _Destroy) (allocator, __true_type, __false_type): Likewise.

2019-05-31PR libstdc++/71579 assert that type traits are not misused with incomplete typesAntony Polukhin17-81/+614
This patch adds static asserts for type traits misuse with incomplete classes and unions. This gives a nice readable error message instead of an UB and odr-violations. Some features of the patch: * each type trait has it's own static_assert inside. This gives better diagnostics than the approach with putting the assert into a helper structure and using it in each trait. * the result of completeness check is not memorized by the compiler. This gives no false positive after the first failed check. * some of the compiler builtins already implement the check. But not all of them! So the asserts are in all the type_traits that may benefit from the check. This also makes the behavior of libstdc++ more consistent across different (non GCC) compilers. * std::is_base_of does not have the assert as it works well in many cases with incomplete types 2019-05-31 Antony Polukhin <antoshkka@gmail.com> PR libstdc++/71579 * include/std/type_traits __type_identity, __is_complete_or_unbounded): New helpers for checking preconditions in traits.

2019-05-29PR libstdc++/85494 use rdseed and rand_s in std::random_deviceJonathan Wakely12-95/+490
Add support for additional sources of randomness to std::random_device, to allow using RDSEED for Intel CPUs and rand_s for Windows. When supported these can be selected using the tokens "rdseed" and "rand_s". For *-w64-mingw32 targets the "default" token will now use rand_s, and for other i?86-*-* and x86_64-*-* targets it will try to use "rdseed" first, then "rdrand", and finally "/dev/urandom". To simplify the declaration of std::random_device in <bits/random.h> the constructors now unconditionally call _M_init instead of _M_init_pretr1, and the function call operator now unconditionally calls _M_getval. The library code now decides whether _M_init and _M_getval should use a real source of randomness or the mt19937 engine. Existing code compiled against old libstdc++ headers will still call _M_init_pretr1 and _M_getval_pretr1, but those functions now forward to _M_init and _M_getval if a real source of randomness is available. This means existing code compiled for mingw-w64 will start to use rand_s just by linking to a new libstdc++.dll. * acinclude.m4 (GLIBCXX_CHECK_X86_RDSEED): Define macro to check if the assembler supports rdseed. * config.h.in: Regenerate. * configure: Regenerate. * configure.ac: Use GLIBCXX_CHECK_X86_RDSEED. * config/os/mingw32-w64/os_defines.h (_GLIBCXX_USE_CRT_RAND_S): Define. * doc/html/*: Regenerate. * doc/xml/manual/status_cxx2011.xml: Document new tokens. * include/bits/random.h (random_device::random_device()): Always call _M_init rather than _M_init_pretr1.
