digitalmars.D.learn - iasm, call and dolar sign
Greetings.
While using D iasm I noticed something interesting.
I was trying to get instruction pointer by using call trick and
noticed that in opposite to nasm (and probably others assemblers)
D iasm uses $ as next instruction pointer.
Documentation mentions that dolar sign is usable in Jcc (or jmp
only? not sure) and call instructions.
It doesn't work.

call $ ; this should jump to next instruction and store RIP on
stack
; if I understand correctly?
pop RAX;
Compiler slaps me with information that $ is bad operand for call
instruction.
Am I doing something wrong or it is a bug?
Thanks!

Will answer myself :p
s/call $/call near ptr $
fixed the thing.
Sorry for distributions
