(cmp_return_type, shift_count_type): Type definitions added. (__lshrdi3, __ashldi3, __ashrdi3): word_type of second parameter replaced with shift_count_type. (__cmpdi2, __ucmpdi2): word_type of return type replaced with cmp_return_type. * libgcc2.c (__udivmoddi4, __moddi3): Type of local variable c changed from word_type to Wtype. (__lshrdi3, __ashldi3, __ashrdi3): word_type of second parameter replaced with shift_count_type. (__cmpdi2, __ucmpdi2): word_type of return type replaced with cmp_return_type. * c-common.c (handle_mode_attribute): Handling for libgcc_cmp_return and libgcc_shift_count attribute added. * target-def.h (TARGET_LIBGCC_CMP_RETURN_MODE, TARGET_LIBGCC_SHIFT_COUNT_MODE): New target hooks defined. (TARGET_INITIALIZER): New target hooks added. * targhooks.c (default_libgcc_cmp_return_mode, default_libgcc_shift_count_mode): Default implementations for the new target hooks added. * targhooks.h (default_libgcc_cmp_return_mode, default_libgcc_shift_count_mode): Function prototypes added. * target.h (struct gcc_target): Fields for the new target hooks added. * optabs.c (expand_binop): Use shift_count_mode when expanding shift as library call. (prepare_cmp_insn): Use cmp_return_mode when expanding comparison as library call. * doc/tm.texi (TARGET_LIBGCC_CMP_RETURN_MODE, TARGET_LIBGCC_SHIFT_COUNT_MODE): Documentation added. * config/s390/s390.c (s390_libgcc_cmp_return_mode, s390_libgcc_shift_count_mode): Functions added. (TARGET_LIBGCC_CMP_RETURN_MODE, TARGET_LIBGCC_SHIFT_COUNT_MODE): Target hooks defined.
