Hi all,
I should've asked this long ago, but better late than never.
Has anybody found a site, book, manual, or anything that explains the
ATT/GAS syntax for each instruction. I'm looking for something similar
to the Intel manuals, even tho it's not to that detail. Anything I find
just includes few instructions, and is more assembly language prog book
rather than just GAS syntax manual.
thanks,
Mukesh

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.

Ah, I thought so. I have similar tricks, I usually use gdb to toggle
syntax between AT&T and INTEL, and figure out that way.
