There are two cases: 1. The library has all it needs to provide align_val_t and the new/delete overloads needed to support aligned allocation. 2. The compiler has actually turned the language feature on. There are times where libc++ needs to distinguish between the two. This patch adds the additional macro _LIBCPP_HAS_NO_LIBRARY_ALIGNED_ALLOCATION which denotes when case (1) does not hold. _LIBCPP_HAS_NO_ALIGNED_ALLOCATION is defined whenever _LIBCPP_HAS_NO_LIBRARY_ALIGNED_ALLOCATION is defined, or when the compiler has not enabled the language feature. Additionally this patch cleans up a number of other macros related to detection of aligned allocation machinery. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@344207 91177308-0d34-0410-b5e6-96231b3b80d8
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.
