* config/m68k/m68k-protos.h (output_sibcall): Declare.
(mips_expand_epilogue): Add a bool parameter.
(m68k_legitimize_sibcall_address): Declare.
* config/m68k/m68k.c (TARGET_FUNCTION_OK_FOR_SIBCALL): Define.
(m68k_expand_epilogue): Add a parameter to select between sibling
and normal epilogues. Only generate a return for the latter.
(m68k_ok_for_sibcall_p): New function.
(m68k_legitimize_sibcall_address, output_sibcall): New functions.
* config/m68k/m68k.md (sibcall, *sibcall): New patterns.
(sibcall_value, *sibcall_value): Likewise.
(*call, *call_value): Require !SIBLING_CALL_P.
(epilogue): Update call to m68k_expand_epilogue.
(sibcall_epilogue): New pattern.
