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

This is a constraint error

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

For example: 


/*PRQA S 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)
{
    m <<= pi;          /* Message 0559 */
    m >>= ft;          /* Message 0559 */
    m &=  st;          /* Message 0559 */
}
