- 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. */
