2022-02-18Rollup merge of #93915 - Urgau:rfc-3013, r=petrochenkovMatthias Krüger-2/+89
Implement --check-cfg option (RFC 3013), take 2 This pull-request implement RFC 3013: Checking conditional compilation at compile time (https://github.com/rust-lang/rfcs/pull/3013) and is based on the previous attempt https://github.com/rust-lang/rust/pull/89346 by `@mwkmwkmwk` that was closed due to inactivity. I have address all the review comments from the previous attempt and added some more tests. cc https://github.com/rust-lang/rust/issues/82450 r? `@petrochenkov`

2022-02-13Remove Config::stderrbjorn3-7/+1
1. It captured stdout and not stderr 2. It isn't used anywhere 3. All error messages should go to the DiagnosticOutput instead 4. It modifies thread local state
2022-02-12Move setup_callbacks call to create_compiler_and_runbjorn3-1/+3
This ensures that it is called even when run_in_thread_pool_with_globals is avoided and reduces code duplication between the parallel and non-parallel version of run_in_thread_pool_with_globals

This provides the user with a helpful error message in case a key="value" message was specified but couldn't be parsed.
2022-01-01Emit an error for `--cfg=)`Jakub Kądziołka-19/+19
Fixes #73026 See also: #64467, #89468 The issue stems from a `FatalError` being silently raised in `panictry_buffer`. Normally this is not a problem, because `panictry_buffer` emits the causes of the error, but they are not themselves fatal, so they get filtered out by the silent emitter. To fix this, we use a parser entrypoint which doesn't use `panictry_buffer`, and we handle the error ourselves.

2021-10-23Rollup merge of #89468 - FabianWolff:issue-89358, r=jackh726Matthias Krüger-1/+4
Report fatal lexer errors in `--cfg` command line arguments Fixes #89358. The erroneous behavior was apparently introduced by `@Mark-Simulacrum` in https://github.com/rust-lang/rust/commit/a678e3191197f145451c97c6cc884e15cae38186; 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: https://github.com/rust-lang/rust/blob/edebf77e0090195bf80c0d8cda821e1bf9d03053/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"` ```
