// This test enumerates as many compiler-builtin ungated attributes as
|
|
// possible (that is, all the mutually compatible ones), and checks
|
|
// that we get "expected" (*) warnings for each in the various weird
|
|
// places that users might put them in the syntax.
|
|
//
|
|
// (*): The word "expected" is in quotes above because the cases where
|
|
// warnings are and are not emitted might not match a user's intuition
|
|
// nor the rustc developers' intent. I am really just trying to
|
|
// capture today's behavior in a test, not so that it become enshrined
|
|
// as the absolute behavior going forward, but rather so that we do
|
|
// not change the behavior in the future without even being *aware* of
|
|
// the change when it happens.

//
|
|
// At the time of authoring, the attributes here are listed in the

|
// order that they occur in `librustc_feature`.

// Any builtin attributes that:

|
//
|

// - are not stable, or

|
// attributes without raising an *error* from rustc (note though
|
|
// that warnings are of course expected)
|
|
//
|
|
// have their own test case referenced by filename in an inline
|
|
// comment.
|

//
|
|
// The test feeds numeric inputs to each attribute that accepts them
|

// without error. We do this for two reasons: (1.) to exercise how
