You dislike PRI macros. And I agree with you that PRI is ugly.
However I don't see any consensus to avoid those macros
in qemu code base.
It is too weak to change its type because of its ugliness.
- There is no description on it in CODING_STYLE.
- PRI macros are already widely used in qemu code
and many patches with PRI have been commited.
- Many other part uses explicit sized type, uintN_t, for address.
