| + | :Look at page history. It seems like it came from [[User:ChronicDev|Chronic]]? Hardly imaginable he entered wrong infos. Maybe just very outdated? I have too few experience with ARM and kernel to contribute here. Feel free to remove wrong infos or just mention where it belongs to. --[[User:Http|http]] 01:14, 2 March 2012 (MST) |

i dont know if its right, pls correct me if im wrong :) --Zmaster 13:58, 29 November 2011 (MST)

The following is hardly "bogus".
0x30d2ad54 <chown>: mov r12, #16 ; 0x10, being # of chown
0x30d2ad58 <chown+4>: svc 0x00000080
is a direct disassembly of libSystem. You can see that with gdb on a jb device.
SVC is an ARM instruction to invoke a "supervisor call". The 0x80 is the call #, because the chip allows an interrupt vector, much like Intel's INT instruction. Then, you place the syscall # (in the above example, chown) in r12. morpheus ||3/1/2012, 20:01 EST.
