3273 | /* NOTE: on some targets, addresses and pointers are not necessarily | |
3274 | the same --- for example, on the D10V, pointers are 16 bits long, | |
3275 | but addresses are 32 bits long. See doc/gdbint.texinfo, | |
3276 | ``Pointers Are Not Always Addresses''. | |
3277 | ||
3278 | The upshot is: | |
3279 | - gdb's `struct type' always describes the target's | |
3280 | representation. | |
3281 | - gdb's `struct value' objects should always hold values in | |
3282 | target form. | |
3283 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3284 | address space that the assembler and linker work with. Thus, | |
3285 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3286 | can access any memory on the target, even if the processor has | |
3287 | separate code and data address spaces. | |
3288 | ||
3289 | So, for example: | |
3290 | - If v is a value holding a D10V code pointer, its contents are | |
3291 | in target form: a big-endian address left-shifted two bits. | |
3292 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3293 | sizeof (void *) == 2 on the target. | |
3294 | ||
3295 | In this context, builtin_type_CORE_ADDR is a bit odd: it's a | |
3296 | target type for a value the target will never see. It's only | |
3297 | used to hold the values of (typeless) linker symbols, which are | |
3298 | indeed in the unified virtual address space. */ | |
