Currently we track function addresses using 5// loc::FunctionVal. Because casts can be arbitrary, do we need to model 6// functions with regions? 7typedef void* (*MyFuncTest1)(void); 8 9MyFuncTest1 test1_aux(void); 10void test1(void) { 11 void *x; 12 void* (*p)(void); 13 p = ((void*) test1_aux()); 14 if (p != ((void*) 0)) x = (*p)(); 15} 16 17// Test casts from void* to function pointers.
