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.
