2019-05-16Rollup merge of #60769 - ehuss:rustc-cli-docs, r=steveklabnikMazdak Farrokhzad-2/+1
Update rustc book CLI docs. This adds a little detail (and missing flags) to the rustc book. There is still a lot of information missing, but this seemed like a good step to expanding it.

And also the equality between `Path` and strings, because `Path` is made up of `Symbol`s.

2019-04-29Auto merge of #60006 - nnethercote:json-for-pipelining, r=alexcrichtonbors-3/+3
In JSON output, emit a directive after metadata is generated. To implement pipelining, Cargo needs to know when metadata generation is finished. This is done via a new JSON "directive". Unfortunately, metadata file writing currently occurs very late during compilation, so pipelining won't produce a speed-up. Moving metadata file writing earlier will be a follow-up. r? @alexcrichton
2019-04-30In JSON output, emit a directive after metadata is generated.Nicholas Nethercote-0/+2
To implement pipelining, Cargo needs to know when metadata generation is finished. This commit adds code to do that. Unfortunately, metadata file writing currently occurs very late during compilation, so pipelining won't produce a speed-up. Moving metadata file writing earlier will be a follow-up. The change involves splitting the existing `Emitter::emit` method in two: `Emitter::emit_diagnostic` and `Emitter::emit_directive`. The JSON directives look like this: ``` {"directive":"metadata file written: liba.rmeta"} ``` The functionality is behind the `-Z emit-directives` option, and also requires `--error-format=json`.

2019-04-28Rollup merge of #60270 - alexcrichton:metadata-multi-cgu, r=oli-obkMazdak Farrokhzad-3/+2
rustc: Flag metadata compatible with multiple CGUs It looks like the `OutputType::Metadata` kind in the compiler was misclassified in #38571 long ago by accident as incompatible with codegen units and a single output file. This means that if you emit both a linkable artifact and metadata it silently turns off multiple codegen units unintentionally! This commit corrects the situation to ensure that if `--emit metadata` is used it doesn't implicitly disable multiple codegen units. This will ensure we don't accidentally regress compiler performance when striving to implement pipelined compilation!

2019-04-19Rollup merge of #60045 - estebank:suggest-std, r=petrochenkovMazdak Farrokhzad-0/+5
Suggest appropriate path when calling associated item on bare types When looking at the documentation for `std::f32` or `std::str`, for example, it is easy to get confused and assume `std::f32` and `f32` are the same thing. Because of this, it is not uncommon to attempt writing `f32::consts::PI` instead of the correct `std::f32::consts::PI`. When encountering the former, which results in an access error due to it being an inexistent path, try to access the same path under `std`. If this succeeds, this information is stored for later tweaking of the final E0599 to provide an appropriate suggestion. Fix #26760, fix #46660.

2019-04-14Rollup merge of #59874 - michaelwoerister:pgo-updates-1, r=cramertjMazdak Farrokhzad-6/+32
Clean up handling of `-Z pgo-gen` commandline option. This PR adapts the `-Z pgo-gen` flag to how Clang and GCC handle the corresponding `-fprofile-generate` flag. In particular, the flag now optionally takes a directory to place the profiling data in and allows to omit the argument (instead of having to pass an empty string).
