In the GNU archive here (which came from somewhere, so I imagine you
can find this stuff in the archives), there are two gas tars:

  /usr/source/gnu/gas-1.38.1.tar.Z
  /usr/source/gnu/gas-doc.tar.Z

Inside gas-doc.tar, there is

  a386.texinfo
  gas.texinfo
  texinfo.tex

a386.texinfo is the doc you're looking for (after you TeX it or Info it
in Emacs or demacs).  Here's the beginning (after being Info'ed):

    AT&T Syntax versus Intel Syntax
    -------------------------------

    In order to maintain compatibility with the output of `GCC',
    `as' supports AT&T System V/386 assembler syntax.

And it goes on to explain the syntax differences and opcode naming
schemes.


Have fun,

Pete
