"The mnemonic for the Intel fdivrp
instruction happens to be fdivp in AT&T mode, and the mnemonic for the Intel
fdivp instruction happens to be fdivrp in AT&T mode."

And this is the information I would expected to find in documentation,
otherwise the only way to find it is to look at code dump and
check instruction codes - not very pedagogic to suggest to students.
