Gcc provides many built-in equivalents of C library functions like memcpy or strlen for optimization purposes. stdcxx should take advantage of them when possible to deliver better performance.
Affects all released versions.
This makes a lot of sense. We should definitely do a review and take advantage of not just the gcc built-ins but of other compilers' as well. It can be done piecemeal, one compiler at a time, and we can probably also roll it out in stages starting with 4.2.1.
