Hello,
this patch replaces the inline-assember used in string.h by C implementation.
There are three reasons why I want to suggest this. First, the C-code might
be optimized further by fixed (constant) arguments. Secondly, it is
architecture
independent and so we just need to maintain on code-path. And as
third point, by
inspecting generated assembly code produced by compiler out of C code
vs. inline-assembler
it shows that compiler produces better code. It handles
jump-threading better, and also
improves average executed instructions.
