Without wp-rte Option ok: frama-c -wp -wp-out wp_longlong test_wp_longlong.c [kernel] preprocessing with "gcc -C -E -I. test_wp_longlong.c" [wp] warning: Missing RTE guards

If you use int type in INTEGER32 structure, then its ok.

Additional Information :

struct INTEGER32 { // int value; // Ok long long value; // Fails };

typedef struct INTEGER32 int32;

/*@ requires \valid(x) && \valid(y);

/ void add (int32 x, int32* y){ int32 erg; erg.value = x->value + y->value; }
