builtins.c (expand_builtin_return_addr): Remove tem parameter.
2005-02-17 Andreas Krebbel <krebbel1@de.ibm.com>
* builtins.c (expand_builtin_return_addr): Remove tem parameter.
tem becomes a local variable which is set to the value of the
back end defined INITIAL_FRAME_ADDRESS macro.
(expand_builtin_frame_address): Omit the base parameter to
expand_builtin_return_addr.
(expand_builtin_profile_func): Likewise.
* config/s390/s390.h (INITIAL_FRAME_ADDRESS_RTX): Define new macro.
(DYNAMIC_CHAIN_ADDRESS): Remove the case for the initial frame.
* doc/tm.texi: Documentation for INITIAL_FRAME_ADDRESS_RTX added.
