compiler-rt libunwind libcxx libcxxabi: updated to 12.0.1

What’s New in Libc++ 12.0.0?

New Features

Random device support has been made optional. It’s enabled by default and can \ 
be disabled by building libc++ with -DLIBCXX_ENABLE_RANDOM_DEVICE=OFF. Disabling \ 
random device support can be useful when building the library for platforms that \ 
don’t have a source of randomness, such as some embedded platforms. When this \ 
is not supported, most of <random> will still be available, but \ 
std::random_device will not.
Localization support has been made optional. It’s enabled by default and can \ 
be disabled by building libc++ with -DLIBCXX_ENABLE_LOCALIZATION=OFF. Disabling \ 
localization can be useful when porting to platforms that don’t support the C \ 
locale API (e.g. embedded). When localization is not supported, several parts of \ 
the library will be disabled: <iostream>, <regex>, <locale> \ 
will be completely unusable, and other parts may be only partly available.
If libc++ is compiled with a C++20 capable compiler it will be compiled in C++20 \ 
mode. Else libc++ will be compiled in C++17 mode.
Several unqualified lookups in libc++ have been changed to qualified lookups. \ 
This makes libc++ more ADL-proof.
The libc++ implementation status pages have been overhauled. Like other parts \ 
documentation they now use restructured text instead of html. Starting with \ 
libc++12 the status pages are part of libc++’s documentation.
More C++20 features have been implemented. libc++ C++20 Status has the full \ 
overview of libc++’s C++20 implementation status.
Work has started to implement new C++2b features. libc++ C++2b Status has the \ 
full overview of libc++’s C++2b implementation status.

API Changes

By default, libc++ will _not_ include the definition for new and delete, since \ 
those are provided in libc++abi. Vendors wishing to provide new and delete in \ 
libc++ can build the library with -DLIBCXX_ENABLE_NEW_DELETE_DEFINITIONS=ON to \ 
get back the old behavior. This was done to avoid providing new and delete in \ 
both libc++ and libc++abi, which is technically an ODR violation. Also note that \ 
we couldn’t decide to put the operators in libc++ only, because they are \ 
needed from libc++abi (which would create a circular dependency).
During the C++20 standardization process some new low-level bit functions have \ 
been renamed. Libc++ has renamed these functions to match the C++20 Standard. - \ 
ispow2 has been renamed to has_single_bit - ceil2 has been renamed to bit_ceil - \ 
floor2 has been renamed to bit_floor - log2p1 has been renamed to bit_width
In C++20 mode, std::filesystem::path::u8string() and generic_u8string() now \ 
return std::u8string according to P0428, while they return std::string in C++17. \ 
This can cause source incompatibility, which is discussed and acknowledged in \ 
P1423, but that paper doesn’t suggest any remediation for this \ 
incompatibility.

Fixes
Fixed use of non-default locales on Windows

Log message:
all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
llvm: updated to 9.0.1

9.0.1 is a bug-fix release.

Log message:
lang: align variable assignments

pkglint -Wall -F --only aligned --only indent -r

No manual corrections.

Fixes

Minor fixes to std::chrono operators.
libc++ now correctly handles Objective-C++ ARC qualifiers in std::is_pointer.
std::span general updates and fixes.
Updates to the std::abs implementation.
std::to_chars now adds leading zeros.
Ensure std::tuple is trivially constructible.
std::aligned_union now works in C++03.
Output of nullptr to std::basic_ostream is formatted properly.

Features

Implemented P0608: sane variant converting constructor.
Added ssize function.
Added front and back methods in std::span.
std::is_unbounded_array and std::is_bounded_array added to type traits.
std::atomic now includes many new features and specialization including improved \ 
Freestanding support.
Added std::midpoint and std::lerp math functions.
Added the function std::is_constant_evaluated.
Erase-like algorithms now return size type.
Added contains method to container types.
std::swap is now a constant expression.

Updates

libc++ dropped support for GCC 4.9; we now support GCC 5.1 and above.
libc++ added explicit support for WebAssembly System Interface (WASI).
Progress towards full support of rvalues and variadics in C++03 mode. std::move \ 
and std::forward now both work in C++03 mode.

Log message:
llvm: updated to 8.0.1

LLVM 8.0.1 is now available! Download it now, or read the release notes.

This release contains bug-fixes for the LLVM 8.0.0 release. This
release is API and ABI compatible with 8.0.0.

What’s New in Libc++ 8.0.0?

API Changes

Building libc++ for Mac OSX 10.6 is not supported anymore.
Starting with LLVM 8.0.0, users that wish to link together translation units \ 
built with different versions of libc++’s headers into the same final linked \ 
image MUST define the _LIBCPP_HIDE_FROM_ABI_PER_TU macro to 1 when building \ 
those translation units. Not defining _LIBCPP_HIDE_FROM_ABI_PER_TU to 1 and \ 
linking translation units built with different versions of libc++’s headers \ 
together may lead to ODR violations and ABI issues. On the flipside, code size \ 
improvements should be expected for everyone not defining the macro.
Starting with LLVM 8.0.0, std::dynarray has been removed from the library. \ 
std::dynarray was a feature proposed for C++14 that was pulled from the Standard \ 
at the last minute and was never standardized. Since there are no plans to \ 
standardize this facility it is being removed.
Starting with LLVM 8.0.0, std::bad_array_length has been removed from the \ 
library. std::bad_array_length was a feature proposed for C++14 alongside \ 
std::dynarray, but it never actually made it into the C++ Standard. There are no \ 
plans to standardize this feature at this time. Formally speaking, this removal \ 
constitutes an ABI break because the symbols were shipped in the shared library. \ 
However, on macOS systems, the feature was not usable because it was hidden \ 
behind availability annotations. We do not expect any actual breakage to happen \ 
from this change.
