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. (TARGET_INITIALIZER): Use it. * c-common.c (handle_mode_attribute): Support "unwind_word" mode attribute. * unwind-generic.h (_Unwind_Word, _Unwind_Sword): Use it. * except.c (init_eh): Use targetm.unwind_word_mode () instead of word_mode to access SjLj_Function_Context member "data". (sjlj_emit_dispatch_table): Likewise. Also, perform type conversion from targetm.eh_return_filter_mode () to targetm.unwind_word_mode () if they differ. * builtin-types.def (BT_UNWINDWORD): New primitive type. (BT_FN_UNWINDWORD_PTR): New function type. (BT_FN_WORD_PTR): Remove. * builtins.def (BUILT_IN_EXTEND_POINTER): Use BT_FN_UNWINDWORD_PTR. * except.c (expand_builtin_extend_pointer): Convert pointer to targetm.unwind_word_mode () instead of word_mode. * config/spu/spu-protos.h (spu_eh_return_filter_mode): Remove. * config/spu/spu.c (spu_eh_return_filter_mode): Remove. (spu_unwind_word_mode): New function. (TARGET_EH_RETURN_FILTER_MODE): Do not define. (TARGET_UNWIND_WORD_MODE): Define. * config/spu/t-spu-elf (TARGET_LIBGCC2_CFLAGS): Remove -D__word__=SI.
