STYLE REQUIREMENTS
==================

1. Most code in this sub-directory is expected to be upstreamed into glibc so
   the GNU Coding Standard and glibc specific conventions should be followed
   to ease upstreaming.

2. ABI and symbols: the code should be written so it is suitable for inclusion
   into a libc with minimal changes. This e.g. means that internal symbols
   should be hidden and in the implementation reserved namespace according to
   ISO C and POSIX rules. If possible the built shared libraries and static
   library archives should be usable to override libc symbols at link time (or
   at runtime via LD_PRELOAD). This requires the symbols to follow the glibc ABI
   (other than symbol versioning), this cannot be done reliably for static
   linking so this is a best effort requirement.

3. API: include headers should be suitable for benchmarking and testing code
   and should not conflict with libc headers.


CONTRIBUTION GUIDELINES FOR string SUB-DIRECTORY
================================================
1. Code:
   - The assumptions of the code must be clearly documented.

   - Assembly style should be consistent across different implementations.


2. Performance:
   - Benchmarking is needed on several microarchitectures.
