Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @estebank (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 Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed.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.

@estebank since this adds new target platforms, shouldn't this be tagged for release notes?

Package changes:

bump bootstraps to 1.51.0.
adjust patches and cargo checksums as required
1.51 failed to build natively on 32-bit armv7, there is hope that this is fixed with 1.52. (1.51 can be built with netbsd32 emulation on a aarch64 system).

Upsteream changes:

Version 1.52.0 (2021-05-06)

Language

Added the unsafe_op_in_unsafe_fn lint, which checks whether the unsafe code in an unsafe fn is wrapped in a unsafe block. This lint is allowed by default, and may become a warning or hard error in a future edition.
You can now cast mutable references to arrays to a pointer of the same type as the element.

Compiler

Upgraded the default LLVM to LLVM 12.

Added tier 3* support for the following targets.

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

Libraries

Stabilised APIs

The following previously stable APIs are now const.

Rustdoc

Rustdoc lints are now treated as a tool lint, meaning that lints are now prefixed with rustdoc:: (e.g. #[warn(rustdoc::non_autolinks)]).

Using the old style is still allowed, and will become a warning in a future release.
Rustdoc now supports argument files.
Rustdoc now generates smart punctuation for documentation.
You can now use "task lists" in Rustdoc Markdown. E.g.
```
- [x] Complete
- [ ] Todo
```

Misc

You can now pass multiple filters to tests. E.g. cargo test -- foo bar will run all tests that match foo and bar.
Rustup now distributes PDB symbols for the std library on Windows, allowing you to see std symbols when debugging.

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.

Compatibility Notes

[Cargo build scripts are now forbidden from setting RUSTC_BOOTSTRAP.] cargo/9181
Removed support for the x86_64-rumprun-netbsd target.
[Deprecated the x86_64-sun-solaris target in favor of x86_64-pc-solaris.] 82216
Rustdoc now only accepts ,, , and \t as delimiters for specifying languages in code blocks.
Rustc now catches more cases of pub_use_of_private_extern_crate
Changes in how proc macros handle whitespace may lead to panics when used with older proc-macro-hack versions. A cargo update should be sufficient to fix this in all cases.

Upstream changes:

Version 1.52.1 (2021-05-10)

This release disables incremental compilation, unless the user has explicitly opted in via the newly added RUSTC_FORCE_INCREMENTAL=1 environment variable.

This is due to the widespread, and frequently occuring, breakage encountered by Rust users due to newly enabled incremental verification in 1.52.0. Notably, Rust users should upgrade to 1.52.0 or 1.52.1: the bugs that are detected by newly added incremental verification are still present in past stable versions, and are not yet fixed on any channel. These bugs can lead to miscompilation of Rust binaries.

These problems only affect incremental builds, so release builds with Cargo should not be affected unless the user has explicitly opted into incremental. Debug and check builds are affected.

See 84970 for more details.
