tests/ui/hello_world/main.rs: Remove FIXME The purpose of the test is to make sure that compiling hello world produces no compiler output. To properly test that, we need to run the entire compiler pipeline. We don't want the test to pass if codegen accidentally starts writing to stdout. So keep it as build-pass. 2023-07-27 08:14:34 +00:00			`//@ build-pass`
