// Target-specific compilation in rustc used to have case-by-case peculiarities in 2014,
|
|
// with the compiler having redundant target types and unspecific names. An overarching rework
|
|
// in #16156 changed the way the target flag functions, and this test attempts compilation
|
|
// with the target flag's bundle of new features to check that compilation either succeeds while
|
|
// using them correctly, or fails with the right error message when using them improperly.
|
|
// See https://github.com/rust-lang/rust/pull/16156
