Here are some tips.  Full documentation is available, check the faq for
details

1) Instructions must have a size suffix
2) Operands go src, dst instead of dst,src
3) Memory references are     'disp (base,index,scale)'
4) Registers must be preceded with a % (must use 2 %s to escape properly in
inline)
5) Immediates must be preceded with a $

Example (untested)

movl $5, 20(%eax,%esi,2)
