2019-10-25Remove lint callback from driverMark Rousskov-2/+0
This is leftover from a restructuring of lint registration for drivers; it should now happen via the register_lints field on Config rather than this function.

2019-10-23Rollup merge of #65193 - Mark-Simulacrum:lockless-lintstore, r=nikomatsakisMazdak Farrokhzad-9/+19
Lockless LintStore This removes mutability from the lint store after registration. Each commit stands alone, for the most part, though they don't make sense out of sequence. The intent here is to move LintStore to a more parallel-friendly architecture, although also just a cleaner one from an implementation perspective. Specifically, this has the following changes: * We no longer implicitly register lints when registering lint passes * For the most part this means that registration calls now likely want to call something like: `lint_store.register_lints(&Pass::get_lints())` as well as `register_*_pass`. * In theory this is a simplification as it's much easier for folks to just register lints and then have passes that implement whichever lint however they want, rather than necessarily tying passes to lints. * Lint passes still have a list of associated lints, but a followup PR could plausibly change that * This list must be known for a given pass type, not instance, i.e., `fn get_lints()` is the signature instead of `fn get_lints(&self)` as before. * We do not store pass objects, instead storing constructor functions. This means we always get new passes when running lints (this happens approximately once though for a given compiler session, so no behavior change is expected). * Registration API is _much_ simpler: generally all functions are just taking `Fn() -> PassObject` rather than several different `bool`s.

2019-10-17Update API to be more compatible with plugin needsMark Rousskov-0/+3
Move to using Box<dyn Fn() -> ...> so that we can let plugins register state. This also adds a callback that'll get called from plugin registration so that Clippy and other tools can register lints without using the plugin API. The plugin API still works, but this new API is more compatible with drivers other than rustc.

2019-09-29Rollup merge of #64799 - Aaron1011:fix/double-panic, r=Mark-SimulacrumMazdak Farrokhzad-1/+1
Fix double panic when printing query stack during an ICE On the latest nightly, any call to `bug` or `span_bug` will result in two panics - the first one as a normal result of calling `bug` / `span_bug`, and the second as a result of trying to print the query stack from the panic handler. This is caused by the query-printing code attempting to acquire a lock on `HandlerInnder`, which is still being held by `bug`. This PR moves the actual panic out of `HandlerInner`, into `Handler`. This allows us to release the lock on `HandlerInner` before triggering the panic, ensuring that the panic handler will be able to acquire the lock if necessary.

2019-09-26Use existing Handler to print query stackAaron Hill-1/+1
When the panic handler is run, the existing Handler may be in a weird state if it was responsible for triggering the panic. By using a freshly created Handler, we avoid trying to re-entrantly lock a HandlerInner, which was causing a double panic on ICEs.

Refactor librustc_errors::Handler API This should be reviewed by-commit. The last commit moves all fields into an inner struct behind a single lock; this is done to prevent possible deadlocks in a multi-threaded compiler, as well as inconsistent state observation.

Use `panic::set_hook` to print the ICE message This allows custom frontends and backends to override the hook with their own, for example to point people to a different issue tracker. ICE messages are printed in a slightly different order now. Nightly prints: ``` thread 'rustc' panicked at 'called `Option::unwrap()` on a `None` value', src/libcore/option.rs:347:21 note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace. error: aborting due to 2 previous errors Some errors have detailed explanations: E0277, E0658.

2019-08-22Auto merge of #63175 - jsgf:argsfile, r=jsgfbors-8/+82
rustc: implement argsfiles for command line Many tools, such as gcc and gnu-ld, support "args files" - that is, being able to specify @file on the command line. This causes `file` to be opened and parsed for command line options. They're separated with whitespace; whitespace can be quoted with double or single quotes, and everything can be \\-escaped. Args files may recursively include other args files via `@file2`. See https://sourceware.org/binutils/docs/ld/Options.html#Options for the documentation of gnu-ld's @file parameters. This is useful for very large command lines, or when command lines are being generated into files by other tooling.

This will make @path work with miri and other non-standard entrypoints. Also since this simplifies librustc_driver::args, move it into a simple source file. Also remove the tests since they're doing nothing more than checking `str::lines` has the right behaviour.

2019-08-19rustc: implement argsfiles for command lineJeremy Fitzhardinge-4/+246
This makes `rustc` support `@path` arguments on the command line. The `path` is opened and the file is interpreted as new command line options which are logically inserted at that point in the command-line. The options in the file are one per line. The file is UTF-8 encoded, and may have either Unix or Windows line endings. It does not support recursive use of `@path`. This is useful for very large command lines, or when command-lines are being generated into files by other tooling.
