This kind of function pointers is used very often in qemu.
The new data type uses format checking with GCC_FMT_ATTR
and will be used in later patches.

One is what type specifier to use (and it is a correctness issue), the other is what width to use (and it is an aesthetics issue). The patch fixes the correctness issue and makes the aesthetic part worse. I agree that a better fix would be to cast to uint32_t as it is done for crX, but this patch is anyway better than nothing because right now DR7 is printed incorrectly _exactly on 64-bit guests running on 32-bit mode_. An even better fix than uint32_t would be to introduce TARGET_FMT_8lx (which maps to "%08"PRI_x64) so that, if for some reason the high 32-bit are not zero, they will be shown.

We already had a similar discussion about TARGET_FMT_PLX, see http://www.mail-archive.com/qemu-devel@nongnu.org/msg42977.html. There I suggested to define PRIxTPA (format specifier for a target physical address). We could also add a PRIxTUL (for target_ulong), so it would be possible to output "%04" PRIxTUL or "%08" PRIxTUL. Thus we could avoid the need for TARGET_FMT_8lx, TARGET_FMT_4lx and maybe even TARGET_FMT_2lx. Kind regards, Stefan ^ permalink raw reply [flat|nested] 13+ messages in thread
