None that I have found. I learned it by examining the source code to gas, 
and the source for Linux. Then, I began examining the output of gcc.
For the list of opcodes gas supports, you'll probably have to look at the 
source for gas. For usages, I experimented with a couple, and used a 
disassembler to verify things.

Maybe someone else knows of a better way, but that's the way I learned it.
