After this would be builds on CI: master...msizanoen1:riscv-ci
It is put on a separate builder so we can easily add it as a rustc host later.

This is the result of running the x86_64-gnu container on this PR: https://dev.azure.com/rust-lang/rust/_build/results?buildId=16159&view=results (I copy pasted the x86_64-gnu Dockerfile into x86_64-gnu-llvm-7 and removed the commit after it finishes running).
The test succeed with 0 cache misses.
It's probably not cache problem.

Centril's comment says that this PR causes multiple rollups to fail and it is the same test failure (pgo-branch-weights). However it seems that there should not be any reason for the test to fail.

msizanoen1 · 2019-12-28T04:12:19Z

Updating libc is already done in #67594 so this is only porting and updating LLVM to include rust-lang/llvm-project#29 and possibly also https://github.com/alexcrichton/cc-rs/pull/461#issuecomment-569382658

☀️ Test successful - checks-azure
Approved by: alexcrichton
Pushing ef92009 to master...

Version 1.42.0 (2020-03-12) ========================== Language -------- - [You can now use the slice pattern syntax with subslices.][67712] e.g. ```rust fn foo(words: &[&str]) { match words { ["Hello", "World", "!", ..] => println!("Hello World!"), ["Foo", "Bar", ..] => println!("Baz"), rest => println!("{:?}", rest), } } ``` - [You can now use `#[repr(transparent)]` on univariant `enum`s.][68122] Meaning that you can create an enum that has the exact layout and ABI of the type it contains. - [There are some *syntax-only* changes:][67131] - `default` is syntactically allowed before items in `trait` definitions. - Items in `impl`s (i.e. `const`s, `type`s, and `fn`s) may syntactically leave out their bodies in favor of `;`. - Bounds on associated types in `impl`s are now syntactically allowed (e.g. `type Foo: Ord;`). - `...` (the C-variadic type) may occur syntactically directly as the type of any function parameter. These are still rejected *semantically*, so you will likely receive an error but these changes can be seen and parsed by procedural macros and conditional compilation. Compiler -------- - [Added tier 2* support for `armv7a-none-eabi`.][68253] - [Added tier 2 support for `riscv64gc-unknown-linux-gnu`.][68339] - [`Option::{expect,unwrap}` and `Result::{expect, expect_err, unwrap, unwrap_err}` now produce panic messages pointing to the location where they were called, rather than `core`'s internals. ][67887] * Refer to Rust's [platform support page][forge-platform-support] for more information on Rust's tiered platform support. Libraries --------- - [`iter::Empty<T>` now implements `Send` and `Sync` for any `T`.][68348] - [`Pin::{map_unchecked, map_unchecked_mut}` no longer require the return type to implement `Sized`.][67935] - [`io::Cursor` now derives `PartialEq` and `Eq`.][67233] - [`Layout::new` is now `const`.][66254] - [Added Standard Library support for `riscv64gc-unknown-linux-gnu`.][66899] Stabilized APIs --------------- - [`CondVar::wait_while`] - [`CondVar::wait_timeout_while`] - [`DebugMap::key`] - [`DebugMap::value`] - [`ManuallyDrop::take`] - [`matches!`] - [`ptr::slice_from_raw_parts_mut`] - [`ptr::slice_from_raw_parts`] Cargo ----- - [You no longer need to include `extern crate proc_macro;` to be able to `use proc_macro;` in the `2018` edition.][cargo/7700] Compatibility Notes ------------------- - [`Error::description` has been deprecated, and its use will now produce a warning.][66919] It's recommended to use `Display`/`to_string` instead. - [`use $crate;` inside macros is now a hard error.][37390] The compiler emitted forward compatibility warnings since Rust 1.14.0. - [As previously announced, this release reduces the level of support for 32-bit Apple targets to tier 3.][apple-32bit-drop]. This means that the source code is still available to build, but the targets are no longer tested and no release binary is distributed by the Rust project.
