Hello ,
            I am working on a Pascal compiler. I have already changed the
source code from Pascal to C { and this now works both in amigados, and
in linux } where it produces 68000 assembler code { a68k } .
{ a68k uses at&t 's  left to right assembler : mov.l $567,reg }

            I am currently working on a version to produce {linux} x86
output.
 I have written a small library of routines { fgets fputs etc.} in
{linux} x86 'as' code , and have the first 80% of the compiler complete.

             Now need some more information please as I need to convert
{ for example } 68000's seq sne exg etc to x86 'as' code.
             Can you recommend somewhere I can download info on
 gcc's 'as' mnemonics please ?


Thanks

First, go to Intel's website and download their manuals. The main one
you want is "Intel Architecture Software Developer's Manual, Volume 2:
Instruction Set Reference."

Then you can use Linux's "info as" to learn the at&t differences. Go to
Machine Dependencies->i386-Dependent. This will probably provide all the
information (plus a lot more) that you need.
