3484 | /* NOTE: on some targets, addresses and pointers are not necessarily | |
3485 | the same --- for example, on the D10V, pointers are 16 bits long, | |
3486 | but addresses are 32 bits long. See doc/gdbint.texinfo, | |
3487 | ``Pointers Are Not Always Addresses''. | |
3488 | ||
3489 | The upshot is: | |
3490 | - gdb's `struct type' always describes the target's | |
3491 | representation. | |
3492 | - gdb's `struct value' objects should always hold values in | |
3493 | target form. | |
3494 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3495 | address space that the assembler and linker work with. Thus, | |
3496 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3497 | can access any memory on the target, even if the processor has | |
3498 | separate code and data address spaces. | |
3499 | ||
3500 | So, for example: | |
3501 | - If v is a value holding a D10V code pointer, its contents are | |
3502 | in target form: a big-endian address left-shifted two bits. | |
3503 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3504 | sizeof (void *) == 2 on the target. | |
3505 | ||
3506 | In this context, builtin_type_CORE_ADDR is a bit odd: it's a | |
3507 | target type for a value the target will never see. It's only | |
3508 | used to hold the values of (typeless) linker symbols, which are | |
3509 | indeed in the unified virtual address space. */ | |
