targhooks.h (struct gcc_target): New member unwind_word_mode.
* targhooks.h (struct gcc_target): New member unwind_word_mode.
(default_unwind_word_mode): Add prototype.
* targhooks.c (default_unwind_word_mode): New function.
(default_eh_return_filter_mode): Return targetm.unwind_word_mode ()
instead of word_mode.
* target-def.h (TARGET_UNWIND_WORD_MODE): New macro.
