  /* NOTE: on some targets, addresses and pointers are not necessarily
     the same --- for example, on the D10V, pointers are 16 bits long,
     but addresses are 32 bits long.  See doc/gdbint.texinfo,
     ``Pointers Are Not Always Addresses''.

     The upshot is:
     - gdb's `struct type' always describes the target's
       representation.
     - gdb's `struct value' objects should always hold values in
       target form.
     - gdb's CORE_ADDR values are addresses in the unified virtual
       address space that the assembler and linker work with.  Thus,
       since target_read_memory takes a CORE_ADDR as an argument, it
       can access any memory on the target, even if the processor has
       separate code and data address spaces.

     So, for example:
     - If v is a value holding a D10V code pointer, its contents are
       in target form: a big-endian address left-shifted two bits.
     - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as
       sizeof (void *) == 2 on the target.

     In this context, builtin_type_CORE_ADDR is a bit odd: it's a
     target type for a value the target will never see.  It's only
     used to hold the values of (typeless) linker symbols, which are
     indeed in the unified virtual address space.  */
