add `DefId` to unsafety violations and display function path in E0133 this enables consumers to access the function definition that was reported to be unsafe 2022-04-24 07:08:23 -05:00			error[E0133]: call to unsafe function `foo` is unsafe and requires unsafe function or block

Add support for 'extern const fn' This works just as you might expect - an 'extern const fn' is a 'const fn' that is callable from foreign code. Currently, panicking is not allowed in consts. When RFC 2345 is stabilized, then panicking in an 'extern const fn' will produce a compile-time error when invoked at compile time, and an abort when invoked at runtime. Since this is extending the language (we're allowing the `const` keyword in a new context), I believe that this will need an FCP. However, it's a very minor change, so I didn't think that filing an RFC was necessary. This will allow libc (and other FFI crates) to make many functions `const`, without having to give up on making them `extern` as well. 2019-09-29 18:22:18 -05:00			`\|`

Remove some errors in UI tests As we now need to run THIR unsafeck before MIR build, errors in unsafeck can cause the compilation to be aborted earlier. 2021-05-15 04:42:10 -05:00			`error: aborting due to previous error`
