Function pointers are supported by the front-end of Frama-C.
Individual plug-ins may support them or not at their convenience. For
the value analysis, it's easy to support them so so they are. For
Jessie and its design-by-contract philosophy, additional features
would be required in the specification language to express the
contract expected of a function pointer (I think).

If the target code only uses the keyword 'interrupt" as in the example
you gave, use:

#define interrupt

This makes the typedef a valid, standard C definition of a function
pointer type SYS_T_PINT.
