Refactor default constructor SFINAE in pair and tuple.

Refactor the recent implicit default constructor changes to match the existing SFINAE style. llvm-svn: 373263

[libc++] Take 2: Implement LWG 2510

2019-09-26T14:51:10+00:00

Summary: LWG2510 makes tag types like allocator_arg_t explicitly default constructible instead of implicitly default constructible. It also makes the constructors for std::pair and std::tuple conditionally explicit based on the explicit-ness of the default constructibility for the pair/tuple's elements. This was previously committed as r372777 and reverted in r372832 due to the commit breaking LLVM's build in C++14 mode. This issue has now been addressed.

Revert r372777: [libc++] Implement LWG 2510 and its follow-ups

2019-09-25T09:10:38+00:00

This also reverts: - r372778: [libc++] Implement LWG 3158 - r372782: [libc++] Try fixing tests that fail on GCC 5 and older - r372787: Purge mentions of GCC 4 from the test suite Reason: the change breaks compilation of LLVM with libc++, for details see http://lists.llvm.org/pipermail/libcxx-dev/2019-September/000599.html llvm-svn: 372832

[NFC][libc++] Add missing EXPLICIT to pair and tuple synopsis

2019-07-22T20:45:23+00:00

The constructors for std::pair and std::tuple have been made conditionally explicit, however the synopsis in the headers do not reflect that. llvm-svn: 366735

This patch makes swap functions constexpr. Both swap overloads, swap_ranges and iter_swap are updated (with tests).

Apply [[nodebug]] to typedefs throughout the STL.

2019-06-12T02:03:31+00:00

When applied to a typedef or alias template, the [[nodebug]] attribute makes the typedef transparent to the debugger, so instead of seeing `std::__function::__alloc_func::type, allocator, void()>::_Target` you see `void(&)()` as the type of the variable in your debugger. Removing all this SFINAE noise from debug info has huge binary size wins, in addition to improving the readability. For now this change is on by default. Users can override it by specifying -D_LIBCPP_NODEBUG_TYPE= llvm-svn: 363117

[libc++] Declare std::tuple_element as struct instead of class

2019-04-01T16:39:34+00:00

Similarly to https://reviews.llvm.org/rL350972, this revision changes std::tuple_element from class to struct. Fixes PR41331. Thanks to Jan Wilken Dörrie for the patch. Differential Revision: https://reviews.llvm.org/D60069 llvm-svn: 357411
