## This test checks that:
|
|
## - __mod_init_func is replaced by __init_offsets.
|
|
## - __mod_init_func has type S_INIT_FUNC_OFFSETS.
|
|
## - initializers show up in the order their parent objects are specified on the
|
|
## command line, and in the order they show up within __mod_init_func.
|
|
## - for undefined and dylib symbols, stubs are created, and the offsets point to those.
|
|
## - offsets are relative to __TEXT's address, they aren't an absolute virtual address.
|
|
## - symbols defined within __mod_init_func are ignored.
