|
||
|
||
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. */

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. */
