At first I thought it might have something to do with C++. But then I
looked a little closer and then it looked like it is building up
information about information contained in a linked list called
"gdb_objc_trampolines".

One of the strategies for speeding up ObjC dispatch was for the runtime to
include a vtable that did direct dispatch for some very common methods (e.g.
-[NSArray count]). Since method dispatch is dynamic, we always have to figure
out the implementation for a given selector, so we had to be able
Thanks for the answer, it makes it clearer.
I have my own Objective-C runtime, and I am using AppleV1 as a starting point
for my own LanguageRuntime plugin. I didn't even know, that the vtab wasn't
used anymore in Apple's Objective-C :)
