// The signatures for these functions are the same and they specify their
// parameter with the restrict qualifier. In C++, however, we are more
// indulgent and we do not match based on this qualifier. Thus, the given
// signature should match for both of the declarations below, i.e the summary
// should be loaded for both of them.

// CHECK: Loaded summary for: void __test_restrict_param_0(void *p)
// CHECK: Loaded summary for: void __test_restrict_param_1(void *__restrict p)

// Must have at least one call expression to initialize the summary map.
