Bug #: 13800
Summary: wrong disassemble result in Xcode 4.4.1 both in
Disassembly window and lldb command window
Product: lldb
Version: unspecified
Platform: PC
OS/Version: MacOS X
Status: NEW
Severity: enhancement
Priority: P
Component: All Bugs
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
When I tried to have a look at the disassembly code of "objc_msgSend", I got
following results:
In the disassembly area:
UIKit`symbol stub for: objc_msgSend:
0xaca71a: jmpl *6483864
In the output area:
(lldb) disassemble -mbr -s 0xaca71a
UIKit`symbol stub for: objc_msgSend
-> 0xaca71a: ff 25 98 ef 62 00 jmpl *6483864
UIKit`symbol stub for: objc_msgSendSuper2
0xaca720: ff 25 9c ef 62 00 jmpl *6483868
UIKit`symbol stub for: objc_msgSendSuper2_stret
0xaca726: ff 25 a0 ef 62 00 jmpl *6483872
UIKit`symbol stub for: objc_msgSend_fpret
0xaca72c: ff 25 a4 ef 62 00 jmpl *6483876
UIKit`symbol stub for: objc_msgSend_stret
0xaca732: ff 25 a8 ef 62 00 jmpl *6483880
(lldb) memory read 0xaca71a
0x00aca71a: ff 25 98 4f c4 00 ff 25 9c 4f c4 00 ff 25 a0 4f .%.O...%.O...%.O
0x00aca72a: c4 00 ff 25 a4 4f c4 00 ff 25 a8 4f c4 00 ff 25 ...%.O...%.O...%
The disassembly results in the disassembly area and returned by the lldb
command "disassemble" are not correct, the results returned by lldb command
"memory read" and in memory view are correct.
