Unconditionally change std::string's alignment to 8. This change saves memory by providing the allocator more freedom to allocate the most efficient size class by dropping the alignment requirements for std::string's pointer from 16 to 8. This changes the output of std::string::max_size, which makes it ABI breaking. That said, the discussion concluded that we don't care about this ABI break. and would like this change enabled universally. The ABI break isn't one of layout or "class size", but rather the value of "max_size()" changes, which in turn changes whether `std::bad_alloc` or `std::length_error` is thrown for large allocations. This change is the child of PR #68807, which enabled the change behind an ABI flag.
libc++ Documentation ==================== The libc++ documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc++ with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBCXX_INCLUDE_DOCS=ON After configuring libc++ with these options the make rule `docs-libcxx-html` should be available. The documentation in this directory is published at https://libcxx.llvm.org. It is kept up-to-date by a build bot: https://lab.llvm.org/buildbot/#/builders/publish-sphinx-docs. If you notice that the documentation is not updating anymore, please contact one of the maintainers.
