* config/m68k/m68k-protos.h (m68k_interrupt_function_p): Declare.
(m68k_movem_pattern_p, m68k_output_movem): Likewise.
(m68k_expand_prologue, m68k_expand_epilogue): Likewise.
* config/m68k/m68k.h (EPILOGUE_USES): Define. Treat all registers
as being live on exit from an interrupt function.
(PRINT_OPERAND_PUNCT_VALID_P): Return true for '?'.
* config/m68k/m68k.c (MIN_MOVEM_REGS, MIN_FMOVEM_REGS): New macros.
(m68k_frame): Remove reg_rev_mask and fpu_rev_mask.
(TARGET_ASM_FUNCTION_PROLOGUE, TARGET_ASM_FUNCTION_EPILOGUE): Delete.
(m68k_interrupt_function_p): Globalize.
(m68k_compute_frame_layout): Remove reverse mask code.
(m68k_emit_movem, m68k_set_frame_related): New functions.
(m68k_output_function_prologue): Delete in favor of...
(m68k_expand_prologue): ...this new function.
(m68k_output_function_epilogue): Delete in favor of...
(m68k_expand_epilogue): ...this new function.
(m68k_split_offset, m68k_movem_pattern_p, m68k_output_movem): New
functions.
(print_operand): Handle %?.
* config/m68k/m68k.md (UNSPEC_SIN, UNSPEC_COS): Remove excess space.
(UNSPEC_GOT, A1_REG, PIC_REG, FP0_REG): New constants.
(prologue, epilogue): New patterns.
(return): Turn into a define_expand.
(*return): New pattern, derived from old "return" pattern. Use rte
rather than rts for interrupt functions. Only use rtd if the pop
count is nonzero.
(*m68k_store_multiple, *m68k_store_multiple_automod): New patterns.
(*m68k_load_multiple, *m68k_load_multiple_automod): Likewise.
(link, *link, unlink, *unlink, load_got): Likewise.
