3324 - gdb's `struct type' always describes the target's
3326 - gdb's `struct value' objects should always hold values in
3328 - gdb's CORE_ADDR values are addresses in the unified virtual
3329 address space that the assembler and linker work with. Thus,
3330 since target_read_memory takes a CORE_ADDR as an argument, it
3331 can access any memory on the target, even if the processor has
3332 separate code and data address spaces.
3335 - If v is a value holding a D10V code pointer, its contents are
3336 in target form: a big-endian address left-shifted two bits.
3337 - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as
3338 sizeof (void *) == 2 on the target.
3340 In this context, builtin_type_CORE_ADDR is a bit odd: it's a
3341 target type for a value the target will never see. It's only
