| error[E0658]: floating point arithmetic is not allowed in constant functions |
| --> $DIR/const-extern-fn-min-const-fn.rs:5:42 |

| LL | const unsafe extern "C" fn use_float() { 1.0 + 1.0; } |
| | ^^^^^^^^^ |

| = help: add `#![feature(const_fn_floating_point_arithmetic)]` to the crate attributes to enable |

| error: pointers cannot be cast to integers during const eval |
| --> $DIR/const-extern-fn-min-const-fn.rs:7:48 |
| | |
| LL | const extern "C" fn ptr_cast(val: *const u8) { val as usize; } |
| | ^^^^^^^^^^^^ |
| | |
| = note: at compile-time, pointers do not have an integer value |
| = note: avoiding this restriction via `transmute`, `union`, or raw pointers leads to compile-time undefined behavior |
