Re: amd64 missing addressing modes

Dear Berndt,

thanks for this document. It is very useful and I was not aware of its 
existence.
If all current linux distributions are following this document (2014) 9 
registers are available for scratch i.e. AX CX DX SI DI R8 R9 R10 R11
where CX is used as return stack in gforth.

whopping cheers from scotland, anthony
