2019-10-15minimize the rust-std componentJosh Stone-33/+112
This splits out a rustc-dev component with the compiler crates, and keeps the status quo of default installed files on nightly. The default changing to not install compiler libraries by default is left for a future pull request. However, on stable and beta, this does remove the compiler libraries from the set of libraries installed by default, as they are never needed there (per our stability story, they "cannot" be used).

refactor session::config::build_session_options_and_crate_config I'm not exactly sure what happened in https://github.com/rust-lang/rust/pull/65361#issuecomment-541420179 so in an effort to bisect the error I'm extracting out the first commit so it can hopefully land (I suspect the error is in the 2nd-3rd commits.) r? @petrochenkov (I'll r=you when the PR builder is happy)

Remove implicit dependencies on syntax::pprust Part of https://github.com/rust-lang/rust/pull/65324. The main goal here is to facilitate the eventual move of pprust out from libsyntax and because an AST definition typically should not depend on its pretty printer. r? @estebank

self-profiling: Add events for metadata loading (plus a small dep-tracking optimization) This PR - adds self-profiling events related to loading things from crate metadata - makes the compiler cache the `DepNodeIndex` of upstream crates, so that they don't have to be looked up over and over. The commits are best reviewed in isolation. Self-profiling tracking issue: https://github.com/rust-lang/rust/issues/58967 r? @Mark-Simulacrum cc @wesleywiser

2019-10-13Rollup merge of #65370 - Cerberuser:patch-1, r=jonas-schievinkMazdak Farrokhzad-5/+5
Add `dyn` to `Any` documentation I noticed that in documentation to `Any` trait the old trait object syntax is used, which could be confusing for newcomers, since we generally recommend using `dyn Trait` instead of just `Trait`. This PR changes the documentation comment, so that it uses `&dyn Any`, `&mut dyn Any` and `Box<dyn Any>`, correspondingly.

2019-10-13Rollup merge of #65366 - faern:source-on-intostringerror, r=blussMazdak Farrokhzad-21/+1
Implement Error::source on IntoStringError + Remove superfluous cause impls IntoStringError only implemented `Error::cause`, which is deprecated. This implemements `Error::source` instead. `Error::cause` will still work as before, thanks to the default implementation. I think this was the only/last `Error` impl in the standard library to have a cause, but not a source.

2019-10-13Rollup merge of #65346 - RalfJung:nounwind-tests, r=nagisaMazdak Farrokhzad-48/+63
nounwind tests and cleanup This is a follow-up to @pnkfelix' https://github.com/rust-lang/rust/pull/65020. In particular it adds some tests as @nagisa asked. It also does a cleanup that the original PR omitted to reduce backporting risks. I hope I finally managed to write an uncontroversial PR in this area. ;) This should not change any behavior, just test it better.

2019-10-13Rollup merge of #65214 - Amanieu:cfg_atomic, r=alexcrichtonMazdak Farrokhzad-98/+127
Split non-CAS atomic support off into target_has_atomic_load_store This PR implements my proposed changes in https://github.com/rust-lang/rust/issues/32976#issuecomment-518542029 by removing `target_has_atomic = "cas"` and splitting `target_has_atomic` into two separate `cfg`s: * `target_has_atomic = 8/16/32/64/128`: This indicates the largest width that the target can atomically CAS (which implies support for all atomic operations). * ` target_has_atomic_load_store = 8/16/32/64/128`: This indicates the largest width that the target can support loading or storing atomically (but may not support CAS). cc #32976 r? @alexcrichton

2019-10-13Rollup merge of #65069 - crgl:clone-from-vec-deque, r=blussMazdak Farrokhzad-2/+122
Implement Clone::clone_from for VecDeque See #28481. For simple data types with the target much longer than the source, this implementation can be significantly slower than the default (probably due to the use of truncate). However, it should be substantially faster when cloning from nested data structures with similar shapes or when cloning from VecDeques with similar lengths, hopefully more common use cases for clone_from.
