"info gas", in particular you want to read the chapter named
"i386-Dependent".

Then you'd want the x86 manuals from amd or intel for the instructions
themselves but they are documented backwards.

Found it in Debian package binutils-doc.

Now looking deeply impressed at the 4600+ pages pile of

 
https://software.intel.com/sites/default/files/managed/39/c5/325462-sdm-vol-1-2abcd-3abcd.pdf

found on

  https://software.intel.com/en-us/articles/intel-sdm

It seems that at page 571 begins the reference of instructions. Up to
page 1120. Ouch.
(I dimly remember that the book by which i learned the machine language
 of my VIC-20's MOS 6502 processor had about 300 pages.)

Thanks a lot for the hints.
