/* PR c/27273 */ /* { dg-do compile } */ // This used to warn about "overflow in implicit constant conversion", // which was wrong; 512 is never converted to unsigned char. Rather, an // appropriate warning would be that the & expression always evaluates to 0 // because of the limited range of unsigned char. unsigned char rx_async(unsigned char p) { return p & 512; /* { dg-warning "" "" { xfail *-*-* } } */ }
