Remove metadata only codegen backend It is unused and probably broken at the moment.

2019-03-06Make `-Z treat-err-as-bug` take a number of errors to be emittedEsteban Küber-2/+2
`-Z treat-err-as-bug=0` will cause `rustc` to panic after the first error is reported. `-Z treat-err-as-bug=2` will cause `rustc` to panic after 3 errors have been reported.

Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

2019-02-10Rollup merge of #58345 - RalfJung:2nd-filename, r=matthewjasperGuillaume Gomez-1/+9
When there are multiple filenames, print what got interpreted as filenames I have written code that crafts command lines for rustc, and when I get "multiple input filenames provided" it can be quite hard to figure out where in this long list of arguments the mistake is hiding. Probably I passed an argument to a flag that does not expect an argument, but which flag would that be? This changes the error message to print the first two filenames, to make it easier to debug what is going on.

2019-02-06Overhaul `syntax::fold::Folder`.Nicholas Nethercote-4/+5
This commit changes `syntax::fold::Folder` from a functional style (where most methods take a `T` and produce a new `T`) to a more imperative style (where most methods take and modify a `&mut T`), and renames it `syntax::mut_visit::MutVisitor`. The first benefit is speed. The functional style does not require any reallocations, due to the use of `P::map` and `MoveMap::move_{,flat_}map`. However, every field in the AST must be overwritten; even those fields that are unchanged are overwritten with the same value. This causes a lot of unnecessary memory writes. The imperative style reduces instruction counts by 1--3% across a wide range of workloads, particularly incremental workloads. The second benefit is conciseness; the imperative style is usually more concise. E.g. compare the old functional style: ``` fn fold_abc(&mut self, abc: ABC) { ABC { a: fold_a(abc.a), b: fold_b(abc.b), c: abc.c, } } ``` with the imperative style: ``` fn visit_abc(&mut self, ABC { a, b, c: _ }: &mut ABC) { visit_a(a); visit_b(b); } ``` (The reductions get larger in more complex examples.) Overall, the patch removes over 200 lines of code -- even though the new code has more comments -- and a lot of the remaining lines have fewer characters. Some notes: - The old style used methods called `fold_*`. The new style mostly uses methods called `visit_*`, but there are a few methods that map a `T` to something other than a `T`, which are called `flat_map_*` (`T` maps to multiple `T`s) or `filter_map_*` (`T` maps to 0 or 1 `T`s). - `move_map.rs`/`MoveMap`/`move_map`/`move_flat_map` are renamed `map_in_place.rs`/`MapInPlace`/`map_in_place`/`flat_map_in_place` to reflect their slightly changed signatures. - Although this commit renames the `fold` module as `mut_visit`, it keeps it in the `fold.rs` file, so as not to confuse git. The next commit will rename the file.

2019-01-13Always calculate glob map but only for glob usesIgor Matuszewski-2/+0
Previously calculating glob map was *opt-in*, however it did record node id -> ident use for every use directive. This aims to see if we can unconditionally calculate the glob map and not regress performance.

2019-01-06Auto merge of #57286 - alexcrichton:less-thin-2-2, r=nikomatsakisbors-8/+1
bootstrap: Link LLVM as a dylib with ThinLTO (take 2) When building a distributed compiler on Linux where we use ThinLTO to create the LLVM shared object this commit switches the compiler to dynamically linking that LLVM artifact instead of statically linking to LLVM. The primary goal here is to reduce CI compile times, avoiding two+ ThinLTO builds of all of LLVM. By linking dynamically to LLVM we'll reuse the one ThinLTO step done by LLVM's build itself. Lots of discussion about this change can be found [here] and down. A perf run will show whether this is worth it or not! [here]: https://github.com/rust-lang/rust/pull/53245#issuecomment-417015334 --- This PR previously landed in https://github.com/rust-lang/rust/pull/56944, caused https://github.com/rust-lang/rust/issues/57111, and was reverted in https://github.com/rust-lang/rust/pull/57116. I've added one more commit here which should fix the breakage that we saw.

rustc: Move jemalloc from rustc_driver to rustc This commit moves jemalloc to just the rustc binary rather than the rustc_driver shared library, enusring that it's only used for binaries that opt-in to it like rustc rather than other binaries using librustc_driver like rustdoc/rls/etc. This will hopefully address #56980

Always run rustc in a thread cc @ishitatsuyuki @eddyb r? @pnkfelix [Previously](https://github.com/rust-lang/rust/pull/48575) we moved to only producing threads when absolutely necessary. Even before we opted to only create threads in some cases, which [is unsound](https://github.com/rust-lang/rust/pull/48575#issuecomment-380635967) due to the way we use thread local storage.

Instead of maybe storing its own sysroot and maybe deferring to the one in `Session::opts`, just clone the latter when necessary so one is always directly available. This removes the need for the getter.
