(EXPERIMENT) compiletest: Don't set `TARGET` for non-run-make tests #147896

Zalathar · 2025-10-20T02:09:46Z

There seem to be a few UI tests that use environment variable TARGET to avoid problems on i586, but we should probably just permit and use //@ ignore-i586 instead.

The run-make runner explicitly sets TARGET on its own, so run-make tests shouldn't be affected.

This PR is currently just for running try jobs; it's not intended for merging (yet).

Zalathar · 2025-10-20T06:48:53Z

OK, this confirms that i586 still requires special treatment to avoid breaking CI.

But we should be able to just use //@ ignore-i586 for that.

rustbot · 2025-10-20T06:56:21Z

compiletest directives have been modified. Please add or update docs for the
new or modified directive in src/doc/rustc-dev-guide/.

There are a few tests that were trying to skip i586 targets via the `TARGET` environment variable instead, so better to just add support for the directive.
