3540 | the same --- for example, on the D10V, pointers are 16 bits long, | |
3541 | but addresses are 32 bits long. See doc/gdbint.texinfo, | |
3542 | ``Pointers Are Not Always Addresses''. | |
3543 | ||
3544 | The upshot is: | |
3545 | - gdb's `struct type' always describes the target's | |
3546 | representation. | |
3547 | - gdb's `struct value' objects should always hold values in | |
3548 | target form. | |
3549 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3550 | address space that the assembler and linker work with. Thus, | |
3551 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3552 | can access any memory on the target, even if the processor has | |
3553 | separate code and data address spaces. | |
3554 | ||
3555 | So, for example: | |
3556 | - If v is a value holding a D10V code pointer, its contents are | |
3557 | in target form: a big-endian address left-shifted two bits. | |
3558 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3559 | sizeof (void *) == 2 on the target. | |
3560 | ||
3561 | In this context, builtin_type_CORE_ADDR is a bit odd: it's a | |
3562 | target type for a value the target will never see. It's only | |
3563 | used to hold the values of (typeless) linker symbols, which are | |
3564 | indeed in the unified virtual address space. */ | |

3685 | /* Pointer/Address types. */ | |
3686 | ||
3687 | /* NOTE: on some targets, addresses and pointers are not necessarily | |
3688 | the same --- for example, on the D10V, pointers are 16 bits long, | |
3689 | but addresses are 32 bits long. See doc/gdbint.texinfo, | |
3690 | ``Pointers Are Not Always Addresses''. | |
3691 | ||
3692 | The upshot is: | |
3693 | - gdb's `struct type' always describes the target's | |
3694 | representation. | |
3695 | - gdb's `struct value' objects should always hold values in | |
3696 | target form. | |
3697 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3698 | address space that the assembler and linker work with. Thus, | |
3699 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3700 | can access any memory on the target, even if the processor has | |
3701 | separate code and data address spaces. | |
3702 | ||
3703 | So, for example: | |
3704 | - If v is a value holding a D10V code pointer, its contents are | |
3705 | in target form: a big-endian address left-shifted two bits. | |
3706 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3707 | sizeof (void *) == 2 on the target. | |
3708 | ||
3709 | In this context, builtin_type->CORE_ADDR is a bit odd: it's a | |
3710 | target type for a value the target will never see. It's only | |
3711 | used to hold the values of (typeless) linker symbols, which are | |
3712 | indeed in the unified virtual address space. */ | |
