This adds a target for bare MIPS32r2, little endian, softfloat. This target can be used for PIC32 microcontrollers (or possibly for other devices that have a MIPS MCU core such as the M4K core).

Tried to find a name for the target that is in line with the naming scheme apparently used for the other MIPS targets.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @jonas-schievink (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

@rust-highfive rust-highfive added the S-waiting-on-review Status: Awaiting review from the assignee but also interested parties. label Nov 2, 2020

That's funny, I was just about to start working on PIC32 support

Great to read that you are interested in Rust support for these devices, too. BTW: because I did not find any Rust libs for the PIC32 I created PAC crates and wrote some HAL code.

Excellent! Thanks a lot @kiffie.

netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request Feb 14, 2021
@he32
Update lang/rust to version 1.49.0.
6aa9ab6 
Pkgsrc changes:
 * Adjust patches, convert tabs to spaces so that tests pass.
 * Remove patches which are no longer needed (upstream changed)
 * Minor adjustments for SunOS, e.g. disable stack probes.
 * Adjust cargo checksum patching accordingly.
 * Remove commented-out use of PATCHELF on NetBSD, which doesn't work anyway...

Upstream changes:

Version 1.49.0 (2020-12-31)
============================

Language
-----------------------

- [Unions can now implement `Drop`, and you can now have a field in a union
  with `ManuallyDrop<T>`.][77547]
- [You can now cast uninhabited enums to integers.][76199]
- [You can now bind by reference and by move in patterns.][76119] This
  allows you to selectively borrow individual components of a type. E.g.
  ```rust
  #[derive(Debug)]
  struct Person {
      name: String,
      age: u8,
  }

  let person = Person {
      name: String::from("Alice"),
      age: 20,
  };

  // `name` is moved out of person, but `age` is referenced.
  let Person { name, ref age } = person;
  println!("{} {}", name, age);
  ```

Compiler
-----------------------

- [Added tier 1\* support for `aarch64-unknown-linux-gnu`.][78228]
- [Added tier 2 support for `aarch64-apple-darwin`.][75991]
- [Added tier 2 support for `aarch64-pc-windows-msvc`.][75914]
- [Added tier 3 support for `mipsel-unknown-none`.][78676]
- [Raised the minimum supported LLVM version to LLVM 9.][78848]
- [Output from threads spawned in tests is now captured.][78227]
- [Change os and vendor values to "none" and "unknown" for some targets][78951]

\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.

Libraries
-----------------------

- [`RangeInclusive` now checks for exhaustion when calling `contains`
  and indexing.][78109]
- [`ToString::to_string` now no longer shrinks the internal buffer
  in the default implementation.][77997]
- [`ops::{Index, IndexMut}` are now implemented for fixed sized
  arrays of any length.][74989]

Stabilized APIs
---------------

- [`slice::select_nth_unstable`]
- [`slice::select_nth_unstable_by`]
- [`slice::select_nth_unstable_by_key`]

The following previously stable methods are now `const`.

- [`Poll::is_ready`]
- [`Poll::is_pending`]

Cargo
-----------------------
- [Building a crate with `cargo-package` should now be independently
  reproducible.][cargo/8864]
- [`cargo-tree` now marks proc-macro crates.][cargo/8765]
- [Added `CARGO_PRIMARY_PACKAGE` build-time environment
  variable.]  [cargo/8758] This variable will be set if the crate
  being built is one the user selected to build, either with `-p`
  or through defaults.
- [You can now use glob patterns when specifying packages &
  targets.][cargo/8752]


Compatibility Notes
-------------------
- [Demoted `i686-unknown-freebsd` from host tier 2 to target tier
  2 support.][78746]
- [Macros that end with a semi-colon are now treated as statements
  even if they expand to nothing.][78376]
- [Rustc will now check for the validity of some built-in attributes
  on enum variants.][77015] Previously such invalid or unused
  attributes could be ignored.
- Leading whitespace is stripped more uniformly in documentation
  comments, which may change behavior. You read [this post about
  the changes][rustdoc-ws-post] for more details.
- [Trait bounds are no longer inferred for associated types.][79904]

Internal Only
-------------
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance
of rustc and related tools.

- [rustc's internal crates are now compiled using the `initial-exec` Thread
  Local Storage model.][78201]
- [Calculate visibilities once in resolve.][78077]
- [Added `system` to the `llvm-libunwind` bootstrap config option.][77703]
- [Added `--color` for configuring terminal color support to bootstrap.][79004]
