Constraint violations REFERENCE - ISO:C90-6.3.16.2 Compound Assignment - Constraints

This is a constraint error

The left hand operand of the <<=,  >>=,  &=,  |=,  ^= and %= operators must have integral type. For example: 


/*PRQA S 502,2213,2216,3112,3408,3447 ++*/

struct ST {int a; int b;};

extern unsigned int m;
extern int *pi;
extern float ft;
extern struct ST st;

void foo(void)
{
    pi <<= m;          /* Message 0560 */
    ft >>= m;          /* Message 0560 */
    st &=  m;          /* Message 0560 */
}
