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.

LLVM 7.0.0 Release

The release contains the work on trunk up to SVN revision 338536 plus
work on the release branch. It is the result of the community's work
over the past six months, including: function multiversioning in Clang
with the 'target' attribute for ELF-based x86/x86_64 targets, improved
PCH support in clang-cl, preliminary DWARF v5 support, basic support
for OpenMP 4.5 offloading to NVPTX, OpenCL C++ support, MSan, X-Ray
and libFuzzer support for FreeBSD, early UBSan, X-Ray and libFuzzer
support for OpenBSD, UBSan checks for implicit conversions, many
long-tail compatibility issues fixed in lld which is now production
ready for ELF, COFF and MinGW, new tools llvm-exegesis, llvm-mca and
diagtool. And as usual, many optimizations, improved diagnostics, and
bug fixes.

lang: Import libcxx version 6.0.1.

libc++ is a new implementation of the C++ standard library, targeting
C++11.

Features and Goals
 * Correctness as defined by the C++11 standard.
 * Fast execution.
 * Minimal memory use.
 * Fast compile times.
 * ABI compatibility with gcc's libstdc++ for some low-level features
   such as exception objects, rtti and memory allocation.
 * Extensive unit tests.
