\ The syntax is reverse polish. Source and destination are
\ reversed. Size prefixes are used instead of AX/EAX. Example:
\ Intel gives
\ mov ax,bx .w bx ax mov
\ mov eax,[ebx] .d bx ) ax mov
\ add eax,4 .d 4 # ax add
\ add rax,8 .q 8 # ax add
\
\ in .86 mode .w is the default size, in .386 mode .d is default
\ in .amd64 mode .q is default size.
\ .wa, .da, and .qa change address size. .b, .w(a) and .d(a) are not
\ switches like in my assem68k, they are prefixes.
\ [A-D][L|H] implicitly set the .b size. So
\ AH AL mov
\ generates a byte move. Sure you need .b for memory operations
\ like .b ax ) inc which is inc BYTE PTR [eAX]
