* doc/tm.texi (DWARF_ALT_FRAME_RETURN_COLUMN): Do not require
DWARF_FRAME_RETURN_COLUMN to be a general register.
* dwarf2out.c (init_return_column_size): New function, split from...
(expand_builtin_init_dwarf_reg_sizes): ...here. Allow both
DWARF_FRAME_RETURN_COLUMN and DWARF_ALT_FRAME_RETURN_COLUMN
to be nongeneral registers.
* config/m68k/m68k.h (DWARF_FRAME_REGNUM): Only map FP and
integer registers.
(DWARF_FRAME_REGISTERS, DWARF_FRAME_RETURN_COLUMN): Define.
(DWARF_ALT_FRAME_RETURN_COLUMN): Define.
