| 1 | +// Target-specific compilation in rustc used to have case-by-case peculiarities in 2014, |
| 2 | +// with the compiler having redundant target types and unspecific names. An overarching rework |
| 3 | +// in #16156 changed the way the target flag functions, and this test attempts compilation |
| 4 | +// with the target flag's bundle of new features to check that compilation either succeeds while |
| 5 | +// using them correctly, or fails with the right error message when using them improperly. |
