I don't think there is such a thing. There are general rules for writing
operands, effective addresses, and ordering of operands of course. If I had
a specific issue with a particular instruction then I would construct an
example in machine code using .byte directive in a .S file, gcc/gas it to an
object file, and the objdump -d that file to see the AT&T syntax for the
instruction.
