hi:
here is the disassembly code ,
629: 0f 84 0e 01 00 00 je 73d <acpi_ec_add+0x125>
62f: 68 d0 00 00 00 push $0xd0
634: ff 35 10 00 00 00 pushl 0x10
63a: e8 fc ff ff ff call 63b <acpi_ec_add+0x23>
63f: 89 c3 mov %eax,%ebx
641: 5f pop %edi
642: 58 pop %eax
643: b8 f4 ff ff ff mov $0xfffffff4,%eax
look at the code at 63a address :
63a: e8 fc ff ff ff call 63b <acpi_ec_add+0x23>
e8 is a CALL instruction , but , obviously , 63b is not a subroutin address ,so how does this "call 63b " generate?
amd what does it do ?
thanks!
