There were a couple of places where we needed to call the underlying platform's aligned allocation/deallocation function. Instead of having the same logic all over the place, extract the logic into a pair of helper functions __libcpp_aligned_alloc and __libcpp_aligned_free. The code in libcxxabi/src/fallback_malloc.cpp looks like it could be simplified after this change -- I purposefully did not simplify it further to keep this change as straightforward as possible, since it is touching very important parts of the library. Also, the changes in libcxx/src/new.cpp and libcxxabi/src/stdlib_new_delete.cpp are basically the same -- I just kept both source files in sync. The underlying reason for this refactoring is to make it easier to support platforms that provide aligned allocation through C11's aligned_alloc function instead of posix_memalign. After this change, we'll only have to add support for that in a single place. Differential Revision: https://reviews.llvm.org/D91379 |
