// This is a test with a setup similar to issue 85155, which triggers a const eval error: a const
|
|
// argument value is outside the range expected by the `stdarch` intrinsic.
|
|
//
|
|
// It's not the exact code mentioned in that issue because it depends both on `stdarch` intrinsics
|
|
// only available on x64, and internal implementation details of `stdarch`. But mostly because these
|
|
// are not important to trigger the diagnostics issue: it's specifically about the lack of context
|
|
// in the diagnostics of post-monomorphization errors (PMEs) for consts, happening in a dependency.
|
|
// Therefore, its setup is reproduced with an aux crate, which will similarly trigger a PME
|
|
// depending on the const argument value, like the `stdarch` intrinsics would.
|
|
//
|
|
//@ aux-build: post_monomorphization_error.rs
|
|
//@ build-fail: this is a post-monomorphization error, it passes check runs and requires building
|
|
// to actually fail.
|

extern crate post_monomorphization_error;

|

// This function triggers a PME whenever the const argument does not fit in 1-bit.
