[libc++] Remove some of the uses of aligned_storage inside the library (#161635)

2025-11-11T10:03:02+00:00

`aligned_storage` has been deprecated and will most likely be removed in
a future version of C++. This patch removes some of its uses to avoid
having to work around its removal in the future.

[libc++] Use std::__{scope,exception}_guard throughout the code base (#161322)

2025-10-09T07:32:40+00:00

This simplifies the code quite a bit and seems to improve code size
slightly in some cases.

[libc++] Refactor internal index_sequence API to match the public one (#149475)

2025-07-20T09:23:31+00:00

The internal API is a lot more complicated than it actually needs to be.
This refactors the internal API to match the features and names of the
public one.

[libc++] Remove the `packaged_task::result_type` extension (#147671)

2025-07-10T07:04:49+00:00

No escape hatch added, as there doesn't seem anyone critically relying
on this.

[libc++][NFC] Merge add_{r,l}value_reference.h (#147022)

2025-07-05T16:11:36+00:00

The implementation is now quite simple, so it doesn't make a ton of
sense to have these in separate headers.

[libc++] Don't try to wait on a thread that hasn't started in std::async, take 2 (#130145)

2025-06-26T10:13:19+00:00

If the creation of a thread fails, this causes an idle loop that will
never end because the thread wasn't started in the first place.

This also adds a test for the regression reported in #125433 to make
sure we're not reintroducing it later.

Fixes #125428

Revert "[libc++] Introduce ABI sensitive areas to avoid requiring _LIBCPP_HIDE_FROM_ABI everywhere (#131156)" (#141756)

2025-05-28T16:04:51+00:00

This reverts commit c861fe8a71e64f3d2108c58147e7375cd9314521.

Unfortunately, this use of hidden visibility attributes causes
user-defined specializations of standard-library types to also be marked
hidden by default, which is incorrect. See discussion thread on #131156.

...and also reverts the follow-up commits:

Revert "[libc++] Add explicit ABI annotations to functions from the block runtime declared in <__functional/function.h> (#140592)"
This reverts commit 3e4c9dc299c35155934688184319d391b298fff7.

Revert "[libc++] Make ABI annotations explicit for windows-specific code (#140507)"
This reverts commit f73287e623a6c2e4a3485832bc3e10860cd26eb5.

Revert "[libc++][NFC] Replace a few "namespace std" with the correct macro (#140510)"
This reverts commit 1d411f27c769a32cb22ce50b9dc4421e34fd40dd.

[libc++] Introduce ABI sensitive areas to avoid requiring _LIBCPP_HIDE_FROM_ABI everywhere (#131156)

2025-05-18T13:47:05+00:00

This patch introduces `_LIBCPP_{BEGIN,END}_EXPLICIT_ABI_ANNOTATIONS`,
which allow us to have implicit annotations for most functions, and just
where it's not "hide_from_abi everything" we add explicit annotations.
This allows us to drop the `_LIBCPP_HIDE_FROM_ABI` macro from most
functions in libc++.

[libc++] Use __underlying_type directly in underyling_type_t (#135423)

2025-04-13T09:01:17+00:00

This avoids instantiating multiple classes, reducing compile times. This
patch also introduces `__underyling_type_t` for internal use, similar to
other type traits.

[libc++] Remove _LIBCPP_TEMPLATE_VIS (#134885)

2025-04-09T21:47:57+00:00

The need for `_LIBCPP_TEMPLATE_VIS` has been removed in #133233.
