Hi, Adrian & Friends!
Like the other patch (by that other person), I think it is faster to not do a strlen first.
There are PowerPC architectures, where a strlen is a matter of a single instruction of the CPU. Quote: "PowerPC 405 and 440 instruction sets offer the powerful Determine Left-Most Zero Byte (DLMZB) instruction." That's propably hard to beat. So, if we really want to speed up these things, we should write code which helps the compiler get that optimized instructions for us - by improving the code of strlen() i.e. Reference: http://www-03.ibm.com/chips/power/powerpc/newsletter/sep2003/ppc_process_at_work2.html Greets, Clemens Koller _______________________________ R&D Imaging Devices Anagramm GmbH Rupert-Mayer-Str. 45/1 81379 Muenchen Germany http://www.anagramm-technology.com Phone: +49-89-741518-50 Fax: +49-89-741518-19 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
