Code:


mov eax,var1
push eax   ;offset of var1
push eax + 4  ;offset of var2?
...
...
...
var1 dd 0
var2 dd 0

push eax + 4 is assembled as push eax, push 4
I think is confusing to allow this combination.

I'm almost sure it was discussed already. It is not a bug but a feature. The problem is that "+4" and "+ 4" are the same and that is OK but sometimes is confusing as you said. Things like "push eax + edx" are not allowed since the unary operator can't be applied to registers.

fasm's push instruction allows repetition of operand seperated with space(s). So [i]push eax + 4[/b] is actually

Code:

push eax
push +4
