c-common.c (warn_for_sign_compare): Cast to unsigned when shifting a negative value.
* c-common.c (warn_for_sign_compare): Cast to unsigned when shifting
a negative value.
* c-typeck.c (set_nonincremental_init_from_string): Use
HOST_WIDE_INT_M1U when shifting a negative value.
* rtlanal.c (split_double): Cast to unsigned when shifting a negative
value.
* sched-int.h (UNKNOWN_DEP_COST): Likewise.
