Hi All,

I was wondering if someone could help illuminate me…

I took a very simple objective-c file, "simple" and started looking at
various sections…


Finally I did…

$otool -X -s __DATA __objc_selrefs simple

00003034 00002fec 00002fe7 00002fd7 00002fcc
00003044 00002fc6 00002ff2

$ otool -l simple | grep selrefs -A20
  sectname __objc_selrefs
   segname __DATA
      addr 0x00003034
      size 0x00000018
    offset 8244
     align 2^2 (4)
    reloff 0
    nreloc 0
     flags 0x10000005
 reserved1 0
 reserved2 0

Now, obviously these are where the selectors are, and sure enough when I
start walking the disass I find these addresses coming up.. but if I look
at address 0x3034 I don't see 00002fec or anything the like.., in fact,
using 0xED, I see 68300000 at offset 0x3034... so, where are the selectors?
 Am I missing something, how is this section used??

Any help, pointers would be great, thanks!
