+ for GDB's internal copy of the data. That's why the
+ 'to_fixed_xxx_type' routines take (target) addresses as parameters,
+ rather than struct value*s.
+
+ However, GDB's internal history variables ($1, $2, etc.) are
+ struct value*s containing internal copies of the data that are not, in
+ general, the same as the data at their corresponding addresses in
+ the target. Fortunately, the types we give to these values are all
+ conventional, fixed-size types (as per the strategy described
+ above), so that we don't usually have to perform the
+ 'to_fixed_xxx_type' conversions to look at their values.
+ Unfortunately, there is one exception: if one of the internal
+ history variables is an array whose elements are unconstrained
+ records, then we will need to create distinct fixed types for each
+ element selected. */
