Matthias Krüger 0f81c7faf5 Rollup merge of #89468 - FabianWolff:issue-89358, r=jackh726 ... Report fatal lexer errors in `--cfg` command line arguments Fixes #89358. The erroneous behavior was apparently introduced by `@Mark-Simulacrum` in a678e31911; the idea is to silence individual parser errors and instead emit one catch-all error message after parsing. However, for the example in #89358, a fatal lexer error is created here: edebf77e00/compiler/rustc_parse/src/lexer/mod.rs (L340-L349) This fatal error aborts the compilation, and so the call to `new_parser_from_source_str()` never returns and the catch-all error message is never emitted. I have therefore changed the `SilentEmitter` to silence only non-fatal errors; with my changes, for the rustc invocation described in #89358: ```sh rustc --cfg "abc\"" ``` I get the following output: ``` error[E0765]: unterminated double quote string | = note: this error occurred on the command line: `--cfg=abc"` ```		2021-10-23 05:28:22 +02:00
