New inline versions of string and mem functions (in particular for ia32)
went into the gcc main branch recently. I'll plead again for wasting the
in-kernel definitions, as (a) the compiler can handle builtins more
efficiently than inline asm (f.ex. interleave them with the surrounding
code if useful, optimize them in the context of their use as the compiler
knows their inards (which it doesn't for inline asm)), and (b) compiler
builtins will get much wider exposure, thus reducing the number and
severity of bugs in that code, and finally (c) you get it for free.
