29 # This file just makes sure that the .fini and .init sections do in
30 # fact return. Users may put any desired instructions in those sections.
31 # This file is the last thing linked into any executable.
33 # Note - this macro is complimented by the FUNC_START macro
34 # in crti.S. If you change this macro you must also change
37 # Note - we do not try any fancy optimisations of the return
38 # sequences here, it is just not worth it. Instead keep things
39 # simple. The link register is restored and then the correct
40 # function return instruction is performed.
56 # To ensure nothing is linked at address 0, provide a dummy
57 # .interrupt section. This is in crtn.S to make sure any
58 # user-provided real .interrupt section will get linked
59 # in front of this dummy.
