Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Reply-To: pgcc AT delorie DOT com A bit offtopic, sorry. My intent is to write optimized assembly/MMX code for AMD Athlon 800 MHz (after first checking out the pentium gcc generated code, of course!) Unfortunately, I can not find a datasheet for Athlon. It is impossible to write asm code unless one knows the instruction cycle counts and other related information, like about scheduling. The obvious place http://www.amd.com/products/cpg/athlon/techdocs/index.html doesn't have Athlon datasheets, doesn't talk anything about it, and I cannot find the datasheet anywhere else either. What's going on? Is Athlon so new CPU that there isn't yet a datasheet, or is it just hidden somewhere, where? Also, are there any special useful options for pgcc generating Athlon code, besides those mentioned at pgcc home page? I'm using pgcc-2.95.2.
