this code work with mini FPC core librarys <Bare Bones> for Mac OS
the generated files main & libtest.dylib is 8kb <each> only .
The macho loader requires access to some system functions
(e.g., NSCreateObjectFileImageFromMemory, NSLinkModule)
that are provided by libdyld.dylib. As we don't know the address of libdyld.dylib in memory .
-
we first walk to the very top of the stack.
-
We then start walking downwards on the stack and we inspect
every pointer we find.
-
The trick is that the offset inside of libdyld.dylib must be
present as it's placed there by the dynamic linker as the
return function when main returns.
-
We find the offset, we resolve the functions and from then on,
it's standard loading of macho bundle .
