- - gdb's `struct value' objects should always hold values in

- - gdb's CORE_ADDR values are addresses in the unified virtual

- 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.
