Extract `rustc_ast_passes`, move gating, & refactor linting Based on https://github.com/rust-lang/rust/pull/67770. This PR extracts a crate `rustc_ast_passes`: - `ast_validation.rs`, which is contributed by `rustc_passes` (now only has HIR based passes) -- the goal here is to improve recompilation of the parser, - `feature_gate.rs`, which is contributed by `syntax` and performs post-expansion-gating & final erroring for pre-expansion gating, - `show_span`, which is contributed by `syntax`. To facilitate this, we first have to also: - Move `{leveled_}feature_err{_err}` from `syntax::feature_gate::check` into `rustc_session::parse`. - Move `get_features` into `rustc_parse::config`, the only place it is used. - Move some some lint datatypes and traits, e.g. `LintBuffer`, `BufferedEarlyLint`, `BuiltinLintDiagnostics`, `LintPass`, and `LintArray` into `rustc_session::lint`. - Move all the hard-wired lint `static`s into `rustc_session::lint::builtin`.

build-std compatible sanitizer support ### Motivation When using `-Z sanitizer=*` feature it is essential that both user code and standard library is instrumented. Otherwise the utility of sanitizer will be limited, or its use will be impractical like in the case of memory sanitizer. The recently introduced cargo feature build-std makes it possible to rebuild standard library with arbitrary rustc flags. Unfortunately, those changes alone do not make it easy to rebuild standard library with sanitizers, since runtimes are dependencies of std that have to be build in specific environment, generally not available outside rustbuild process. Additionally rebuilding them requires presence of llvm-config and compiler-rt sources. The goal of changes proposed here is to make it possible to avoid rebuilding sanitizer runtimes when rebuilding the std, thus making it possible to instrument standard library for use with sanitizer with simple, although verbose command: ``` env CARGO_TARGET_X86_64_UNKNOWN_LINUX_GNU_RUSTFLAGS=-Zsanitizer=thread cargo test -Zbuild-std --target x86_64-unknown-linux-gnu ``` ### Implementation * Sanitizer runtimes are no long packed into crates. Instead, libraries build from compiler-rt are used as is, after renaming them into `librusc_rt.*`. * rustc obtains runtimes from target libdir for default sysroot, so that they are not required in custom build sysroots created with build-std. * The runtimes are only linked-in into executables to address issue #64629. (in previous design it was hard to avoid linking runtimes into static libraries produced by rustc as demonstrated by sanitizer-staticlib-link test, which still passes despite changes made in #64780). cc @kennytm, @japaric, @firstyear, @choller

2019-12-11Rollup merge of #67074 - ehuss:extern-options, r=petrochenkovMazdak Farrokhzad-9/+11
Add options to --extern flag. This changes the `--extern` flag so that it can take a series of options that changes its behavior. The general syntax is `[opts ':'] name ['=' path]` where `opts` is a comma separated list of options. Two options are supported, `priv` which replaces `--extern-private` and `noprelude` which avoids adding the crate to the extern prelude. ```text --extern priv:mylib=/path/to/libmylib.rlib --extern noprelude:alloc=/path/to/liballoc.rlib ``` `noprelude` is to be used by Cargo's build-std feature in order to use `--extern` to reference standard library crates. This also includes a second commit which adds the `aux-crate` directive to compiletest. I can split this off into a separate PR if desired, but it helps with defining these kinds of tests. It is based on #54020, and can be used in the future to replace and simplify some of the Makefile tests.
