Sat, 21 Dec 2024 12:01:48 +0000

[libc++][C++03] Use `__cxx03/` headers in C++03 mode (#109002)This patch implements the forwarding to frozen C++03 headers asdiscussed inhttps://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc. In theRFC, we initially proposed selecting the right headers from the Clangdriver, however consensus seemed to steer towards handling this in thelibrary itself. This patch implements that direction.At a high level, the changes basically amount to making each publicheader look like this:```// inside #ifdef _LIBCPP_CXX03_LANG# include <__cxx03/vector>#else // normal content#endif```In most cases, public headers are simple umbrella headers so there isn'tmuch code in the #else branch. In other cases, the #else branch containsthe actual implementation of the header. List of files: /llvm-project/libcxx/include/list

Fri, 13 Dec 2024 19:17:56 +0000

[libc++] Granularize the header (#119270)This disentangles the code which previously had a mix of many #ifdefs, a non-versioned namespace and a versioned namespace. It also makes it clearer which parts of are implemented on Windows by including . List of files: /llvm-project/libcxx/include/list

Tue, 10 Dec 2024 15:02:12 +0000

[libc++] Add #if 0 block to all the top-level headers (#119234)Including The frozen C++03 headers results in a lot of formattingchanges in the main headers, so this splits these changes into aseparate commit instead.This is part ofhttps://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc.

397707f7188b6df52de1cff85e08e64e3ee5acc3 - [libc++] __uglify non-conforming member typedef `base` (#112843)

Fri, 18 Oct 2024 15:27:12 +0000

[libc++] __uglify non-conforming member typedef `base` (#112843)Currently, libc++'s `bitset`, `forward_list`, and `list` have non-conforming member typedef name `base`. The typedef is private, but can cause ambiguity in name lookup. Some other classes in libc++ that are either implementation details or not precisely specified by the standard also have member typdef `base`. I think this can still be conforming.

ba87515fea90b5d55836a8e3be63a7e683ce299d - [libc++][RFC] Always define internal feature test macros (#89178)

Sat, 12 Oct 2024 07:49:52 +0000

[libc++][RFC] Always define internal feature test macros (#89178)Currently, the library-internal feature test macros are only defined if the feature is not available, and always have the prefix `_LIBCPP_HAS_NO_`. This patch changes that, so that they are always defined and have the prefix `_LIBCPP_HAS_` instead. This changes the canonical use of these macros to `#if _LIBCPP_HAS_FEATURE`, which means that using an undefined macro (e.g. due to a missing include) is diagnosed now. While this is rather unlikely currently, a similar change in `<__configuration/availability.h>` caught a few bugs. This also improves readability, since it removes the double-negation of `#ifndef _LIBCPP_HAS_NO_FEATURE`. The current patch only touches the macros defined in `<__config>`. If people are happy with this approach, I'll make a follow-up PR to also change the macros defined in `<__config_site>`. List of files: /llvm-project/libcxx/include/list

01df775dc42b62141ad07ad30aaa361ab162b8f5 - [libc++] Take the ABI break for `std::list`'s pointer UB unconditionally (#100585)

Mon, 16 Sep 2024 15:55:33 +0000

[libc++] Take the ABI break for `std::list`'s pointer UB unconditionally (#100585)This ABI break only affects fancy pointer which have a different value representation when pointing to a base of T instead of T itself. This seems like a rather small set of fancy pointers, which themselves already represent a very small niche. This patch swaps a pointer to T with a pointer to base of T in a few library-internal types. List of files: /llvm-project/libcxx/include/list

27c83382d83dce0f33ae67abb3bc94977cb3031f - [libc++] Replace `__compressed_pair` with `[[no_unique_address]]` (#76756)

Mon, 16 Sep 2024 09:08:57 +0000

[libc++] Replace `__compressed_pair` with `[[no_unique_address]]` (#76756)This significantly simplifies the code, improves compile times andimproves the object layout of types using `__compressed_pair` in theunstable ABI. The only downside is that this is extremely ABI sensitiveand pedantically breaks the ABI for empty final types, since the addressof the subobject may change. The ABI of the whole object should not beaffected.Fixes #91266Fixes #93069 List of files: /llvm-project/libcxx/include/list

[libc++][NFC] Use [[__nodiscard__]] unconditionally (#80454)`__has_cpp_attribute(__nodiscard__)` is always true now, so we might as well replace `_LIBCPP_NODISCARD`. It's one less macro that can result in bad diagnostics. List of files: /llvm-project/libcxx/include/list

[libc++] Refactor<__type_traits/is_swappable.h> (#86822)This changes the `is_swappable` implementation to use variable templates first and basing the class templates on that.

Tue, 18 Jun 2024 08:45:30 +0000

[libc++][NFC] Remove unnecessary parens in static_asserts (#95605)These were required a long time ago due to `static_assert` not actually being available in C++03. Now `static_assert` is simply mapped to `_Static_assert` in C++03, making the additional parens unnecessary. List of files: /llvm-project/libcxx/include/list

04f01a2b9cedc291fa7dd941de841dc957c75a33 - [libc++] Make the availability header a sub-header of config (#93083)

Wed, 29 May 2024 01:29:11 +0000

[libc++] Make the __availability header a sub-header of __config (#93083)In essence, this header has always been related to configuration of the library but we didn't want to put it inside <__config> due to complexity reasons. Now that we have sub-headers in <__config>, we can move <__availability> to it and stop including it everywhere since we already obtain the required macros via <__config>.
