And if they\u0027re using cargo, warn them to use rustc directly.\n\n\u003e [!IMPORTANT]\n\u003e First few comments in this pull request refer to changing the flag itself to work on source files. This was instead overruled to warn the user about executing on `.rmeta` files instead of `.rs` files.\n\n\u003cdetails\u003e\u003csummary\u003eOld description\u003c/summary\u003e\n\u003cp\u003e\nThis unstable option has been broken since forever (more than 2.5 years,\nat least), but it\u0027s exactly what I need for debugging the new\nincremental system, so rather than removing it I opted for fixing it.\n\nThe issue was that we were feeding the source file like, `src/lib.rs` instead of the `.rmeta` file. So literally every use of `-Zls\u003d..` was returning  `invalid metadata version found: ..`\n\nThis PR also includes some testing.\n\nRelevant for https://github.com/rust-lang/rust-project-goals/issues/641.\n\n\u003c/p\u003e\n\u003c/details\u003e\n",
