3297 | /* NOTE: on some targets, addresses and pointers are not necessarily | |
3298 | the same --- for example, on the D10V, pointers are 16 bits long, | |
3299 | but addresses are 32 bits long. See doc/gdbint.texinfo, | |
3300 | ``Pointers Are Not Always Addresses''. | |
3301 | ||
3302 | The upshot is: | |
3303 | - gdb's `struct type' always describes the target's | |
3304 | representation. | |
3305 | - gdb's `struct value' objects should always hold values in | |
3306 | target form. | |
3307 | - gdb's CORE_ADDR values are addresses in the unified virtual | |
3308 | address space that the assembler and linker work with. Thus, | |
3309 | since target_read_memory takes a CORE_ADDR as an argument, it | |
3310 | can access any memory on the target, even if the processor has | |
3311 | separate code and data address spaces. | |
3312 | ||
3313 | So, for example: | |
3314 | - If v is a value holding a D10V code pointer, its contents are | |
3315 | in target form: a big-endian address left-shifted two bits. | |
3316 | - If p is a D10V pointer type, TYPE_LENGTH (p) == 2, just as | |
3317 | sizeof (void *) == 2 on the target. | |
