+ /* NOTE: on some targets, addresses and pointers are not necessarily
+ the same --- for example, on the D10V, pointers are 16 bits long,
+ 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. */
