V3546. AUTOSAR. Conversions between pointers to objects and integer types should not be performed.

This diagnostic rule is based on the software development guidelines developed by AUTOSAR (AUTomotive Open System ARchitecture).

Conversions between pointers to objects and integer types can lead to undefined, unspecified, or implementation-specific behavior. For that reason, it's not recommended to use such conversions.

Example of non-compliant code 1:

struct S { int16_t i; int16_t j; } *ps = ....;
int i64 = reinterpret_cast<int>(ps);

Example of non-compliant code 2:

void foo(int i) {}

void wrong_param_type()
  char *pc = ....;
  foo((int) pc); 

Example of non-compliant code 3:

int wrong_return_type()
  double *pd = ....;
  return (int) pd;

This diagnostic is classified as:

  • AUTOSAR-M5.2.8
  • AUTOSAR-M5.2.9
