@defmac FIND_BASE_TERM (@var{x})
A C expression to determine the base term of address @var{x},
or to provide a simplified version of @var{x} from which @file{alias.c}
-can easily find the base term. This macro is used in only one place:
-@code{find_base_term} in @file{alias.c}.
+can easily find the base term. This macro is used in only two places:
+@code{find_base_value} and @code{find_base_term} in @file{alias.c}.
It is always safe for this macro to not be defined. It exists so
that alias analysis can understand machine-dependent addresses.
