- 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.
+/* Allocate the hash table used by copy_type_recursive to walk
+ types without duplicates. We use OBJFILE's obstack, because
+ OBJFILE is about to be deleted. */
- 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
