When I switch on the Xcode-flag "Accelerated Objective-C Dispatch"
(-fobjc-direct-dispatch) (Tiger only) the code generated for sending
Objective-C messages looks kind of strange:
00001044 bla 0xfffeff00
Note that even otool does not seem to know what this 0xfffeff00 stands
for.
And I can't find the address 0xfffeff00 in any load command, nor do I
see it in the symbol table.
How do I know that 0xfffeff00 stands for _objc_msgSend?
Without Accelerated Objective-C Dispatch the code looks like:
00001024 bl 0x2540 ; symbol stub for: _objc_msgSend
Is this new fashion of sending Objective-C messages documented anywhere?
Kind regards,
Gerriet.
