3317 | The upshot is: | |
3318 | - gdb's `struct type' always describes the target's | |

3320 | - gdb's `struct value' objects should always hold values in | |
3321 | target form. | |
3322 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3323 | address space that the assembler and linker work with. Thus, | |
3324 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3325 | can access any memory on the target, even if the processor has | |
3326 | separate code and data address spaces. | |
3327 | ||
3328 | So, for example: | |
3329 | - If v is a value holding a D10V code pointer, its contents are | |
3330 | in target form: a big-endian address left-shifted two bits. | |
3331 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3332 | sizeof (void *) == 2 on the target. | |
3333 | ||
3334 | In this context, builtin_type_CORE_ADDR is a bit odd: it's a | |
3335 | target type for a value the target will never see. It's only | |
3336 | used to hold the values of (typeless) linker symbols, which are | |
3337 | indeed in the unified virtual address space. */ | |
