3457 | /* NOTE: on some targets, addresses and pointers are not necessarily | |
3458 | the same --- for example, on the D10V, pointers are 16 bits long, | |
3459 | but addresses are 32 bits long. See doc/gdbint.texinfo, | |
3460 | ``Pointers Are Not Always Addresses''. | |
3461 | ||
3462 | The upshot is: | |
3463 | - gdb's `struct type' always describes the target's | |
3464 | representation. | |
3465 | - gdb's `struct value' objects should always hold values in | |
3466 | target form. | |
3467 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3468 | address space that the assembler and linker work with. Thus, | |
3469 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3470 | can access any memory on the target, even if the processor has | |
3471 | separate code and data address spaces. | |
3472 | ||
3473 | So, for example: | |
3474 | - If v is a value holding a D10V code pointer, its contents are | |
3475 | in target form: a big-endian address left-shifted two bits. | |
3476 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3477 | sizeof (void *) == 2 on the target. | |
3478 | ||
46bf5051 UW |
3479 | In this context, objfile_type->builtin_core_addr is a bit odd: |
3480 | it's a target type for a value the target will never see. It's | |

3482 | are indeed in the unified virtual address space. */ | |
