+
+       Provide the hooks needed to support architectures on which
+       pointers are not always simple byte addresses.
+
+       * gdbarch.sh (POINTER_TO_ADDRESS, ADDRESS_TO_POINTER): Two new
+       functions which architectures can redefine, defaulting to
+       generic_pointer_to_address and generic_address_to_pointer.
+       * findvar.c (extract_typed_address, store_typed_address,
+       generic_pointer_to_address, generic_address_to_pointer): New
+       functions.
+       (POINTER_TO_ADDRESS, ADDRESS_TO_POINTER): Provide default
+       definitions.
+       (extract_address, store_address): Doc fixes.
+       * values.c (value_as_pointer): Doc fix.
+       (value_from_pointer): New function.
+       * defs.h (extract_typed_address, store_typed_address): New
+       declarations.
+       * inferior.h (generic_address_to_pointer,
+       generic_pointer_to_address): New declarations.
+       * value.h (value_from_pointer): New declaration.
+       
+       The following changes are all of the general form "Use these
+       functions instead of these other functions."  In each case, the
+       change is because the new calls provide enough information to do
+       the appropriate address / pointer conversions, where the old calls
+       did not, or because the new functions are more appropriately named
+       for the operation being performed.
+       
+       * ax-gdb.c (const_var_ref): Use value_from_pointer, not
+       value_from_longest.
+       * blockframe.c (generic_push_dummy_frame): Use read_pc and
+       read_sp, not read_register.
+       * c-valprint.c (c_val_print): Use extract_typed_address instead of
+       extract_address to extract vtable entries and references.
+       * cp-valprint.c (cp_print_value_fields): Use value_from_pointer
+       instead of value_from_longest to extract the vtable's address.
+       * eval.c (evaluate_subexp_standard): Use value_from_pointer
+       instead of value_from_longest to compute `this', and for doing
+       pointer-to-member dereferencing.
+       * findvar.c (read_register): Use extract_unsigned_integer, not
+       extract_address.
+       (read_var_value): Use store_typed_address instead of store_address
+       for building label values.
+       (locate_var_value): Use value_from_pointer instead of
+       value_from_longest.
+       * hppa-tdep.c (find_stub_with_shl_get): Use value_from_pointer,
+       instead of value_from_longest, to build arguments to __d_shl_get.
+       * printcmd.c (set_next_address): Use value_from_pointer, not
+       value_from_longest.
+       (x_command): Use value_from_pointer, not value_from_longest.
+       * tracepoint.c (set_traceframe_context): Use value_from_pointer,
+       not value_from_longest.
+       * valarith.c (value_add, value_sub): Use value_from_pointer, not
+       value_from_longest.
+       * valops.c (find_function_in_inferior, value_coerce_array,
+       value_coerce_function, value_addr, hand_function_call): Same.
+       * value.h (COERCE_REF): Use unpack_pointer, not unpack_long. 
+       * values.c (unpack_long): Use extract_typed_address to produce
+       addresses from pointers and references, not extract_address.
+       (value_from_longest): Use store_typed_address instead of
+       store_address to produce pointer and reference values.
