// Test that `wrapping_div` only checks divisor once. // This test checks that there is only a single compare against -1 and -1 is not present as a // switch case (the second check present until rustc 1.12). // This test also verifies that a single panic call is generated (for the division by zero case). // compile-flags: -O #![crate_type = "lib"] // CHECK-LABEL: @f #[no_mangle] pub fn f(x: i32, y: i32) -> i32 { // CHECK-COUNT-1: icmp eq i32 %y, -1 // CHECK-COUNT-1: panic // CHECK-NOT: i32 -1, label x.wrapping_div(y) }
