# This file just makes sure that the .fini and .init sections do in
|
|
# fact return. Users may put any desired instructions in those sections.

# Note - this macro is complimented by the FUNC_START macro
|
|
# in crti.S. If you change this macro you must also change
|
|
# that macro match.

|
|
# Note - we do not try any fancy optimisations of the return
|
|
# sequences here, it is just not worth it. Instead keep things
|
|
# simple. The link register is restored and then the correct
|
|
# function return instruction is performed.
