| This directory contains partial re-implementations of some C++ standard library |
| utilities. They are for use with internal LLVM libc code and tests. |
| |
| More utilities can be added on an as needed basis. There are certain rules to |
| be followed for future changes and additions: |
| |
| 1. Only two kind of headers can be included: Other headers from this directory, |
| and free standing C headers. |
| 2. Free standing C headers are to be included as C headers and not as C++ |
| headers. That is, use `#include <stddef.h>` and not `#include <cstddef>`. |
| 3. The utilities should be defined in the namespace `LIBC_NAMESPACE::cpp`. The |
| higher level namespace should have a `__` prefix to avoid symbol name pollution |
| when the utilities are used in implementation of public functions. |
