Verify llvm-needs-components are not empty and match the --target value I recently discovered a test with an empty `llvm-needs-components` entry (fixed in rust-lang/rust#143979) which meant that it didn't work correctly when building Rust with a limited set of LLVM targets. This change makes a pair of improvements to prevent this issue from creeping in again: * When parsing directives with values, `compiletest` will now raise an error if there is an empty value. * Improved the `target_specific_tests` tidy checker to map targets to LLVM components, to verify that any existing `llvm-needs-components` contains the target being used. I also fixed all the issues flagged by the improved tidy checker.
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
