Ok thanks..

One more question. Can I get the reference of global variable in terms of offset from some register like a5 ( for example like move.l 8(%a5),%d0) instead of direct memory address or variable name ?

80000130: 7005 moveq #5,%d0

80000132: 23c0 8000 21ec movel %d0,800021ec <VAR1>

move.l %d0,I

move.l VAR1,I

Hi,

I am declaring the global variable outside a procedure. I want to know the register that is used by this global variable.

VAR
VAR1:INTEGER; attribute(name='VAR1');

When I tried to disassemble the object file, the global variables seems to be residing in the memory instead of a register.

80000130: 7005 moveq #5,%d0

80000132: 23c0 8000 21ec movel %d0,800021ec <VAR1>

Can you please let me know how to identify the register which is used by this variable.

Thanks,
