962 a struct, e.g. "an int at offset 8". A MEMBER TYPE doesn't

964 include the structure type into which it points (for some reason).

3319 /* NOTE: on some targets, addresses and pointers are not necessarily
3320 the same --- for example, on the D10V, pointers are 16 bits long,
3321 but addresses are 32 bits long. See doc/gdbint.texinfo,
3322 ``Pointers Are Not Always Addresses''.
3323
3324 The upshot is:
3325 - gdb's `struct type' always describes the target's
3326 representation.
3327 - gdb's `struct value' objects should always hold values in
3328 target form.
3329 - gdb's CORE_ADDR values are addresses in the unified virtual
3330 address space that the assembler and linker work with. Thus,
3331 since target_read_memory takes a CORE_ADDR as an argument, it
3332 can access any memory on the target, even if the processor has
3333 separate code and data address spaces.
3334
3335 So, for example:
3336 - If v is a value holding a D10V code pointer, its contents are
3337 in target form: a big-endian address left-shifted two bits.
3338 - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as
3339 sizeof (void *) == 2 on the target.
3340
3341 In this context, builtin_type_CORE_ADDR is a bit odd: it's a
3342 target type for a value the target will never see. It's only
3343 used to hold the values of (typeless) linker symbols, which are
3344 indeed in the unified virtual address space. */
