specified atomic widths, e.g. the test with `//@ needs-target-has-atomic: 8,

widths.
- `needs-dynamic-linking` - ignores if target does not support dynamic linking
- `needs-dynamic-linking` — ignores if target does not support dynamic linking
(which is orthogonal to it being unable to create `dylib` and `cdylib` crate types)
- `needs-crate-type` — ignores if target platform does not support one or more
of the comma-delimited list of specified crate types. For example,
`//@ needs-crate-type: cdylib, proc-macro` will cause the test to be ignored
on `wasm32-unknown-unknown` target because the target does not support the
`proc-macro` crate type.
The following directives will check LLVM support:

| `compile-flags` | Flags passed to `rustc` when building the test or aux file | All except for `run-make` | Any valid `rustc` flags, e.g. `-Awarnings -Dfoo`. Cannot be `-Cincremental`. |
| `edition` | Alias for `compile-flags: --edition=xxx` | All except for `run-make` | Any valid `--edition` value |
| `rustc-env` | Env var to set when running `rustc` | All except for `run-make` | `<KEY>=<VALUE>` |
| `unset-rustc-env` | Env var to unset when running `rustc` | All except for `run-make` | Any env var name |
| `incremental` | Proper incremental support for tests outside of incremental test suite | `ui`, `crashes` | N/A |
| `no-prefer-dynamic` | Don't use `-C prefer-dynamic`, don't build as a dylib via a `--crate-type=dylib` preset flag | `ui`, `crashes` | N/A |
