In case of glibc, it may choose to run an sse4.2 version where 16 bytes are compared at a time. Maybe we encounter "string not equal" much often than "string equal" and such an optimization is unncessary, I don't know. Measured numbers say it's unncessary as my cpu supports sse4.2. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
