This adds a new rustc target-configuration called 'x86_64-unknown_uefi'. Furthermore, it adds a UEFI base-configuration to be used with other targets supported by UEFI (e.g., i386, armv7hl, aarch64, itanium, ...). UEFI systems provide a very basic operating-system environment, meant to unify how systems are booted. It is tailored for simplicity and fast setup, as it is only meant to bootstrap other systems. For instance, it copies most of the ABI from Microsoft Windows, rather than inventing anything on its own. Furthermore, any complex CPU features are disabled. Only one CPU is allowed to be up, no interrupts other than the timer-interrupt are allowed, no process-separation is performed, page-tables are identity-mapped, ... Nevertheless, UEFI has an application model. Its main purpose is to allow operating-system vendors to write small UEFI applications that load their kernel and terminate the UEFI system. However, many other UEFI applications have emerged in the past, including network-boot, debug-consoles, and more. This UEFI target allows to compile rust code natively as UEFI applications. No standard library support is added, but libcore can be used out-of-the-box if a panic-handler is provided. Furthermore, liballoc works as well, if a `GlobalAlloc` handler is provided. Both have been tested with this target-configuration. Note that full libstd support is unlikely to happen. While UEFI does have standardized interfaces for networking and alike, none of these are mandatory and they are unlikely to be shipped in common consumer firmwares. Furthermore, several features like process-separation are not available (or only in very limited fashion). Those parts of libstd would have to be masked.

The (currently) single unit test of the compiletest tool was never
executed on CI. At least I couldn't find any references of it in the
logs. This adds a test suite for compiletest so that our tester is
tested, too.
The compiletest tests can then also be executed with:
./x.py test src/tools/compiletest

fix rust-lang/rust issue rust-lang#50583 Rationale for the fix is in rust-lang#50583. I've verified that before the fix /musl-armhf/lib/libc.a is riddled with the illegal variant of vmov.f64 and after the fix the version built doesn't contain any of these illegal instructions. I originally thought that the arm-linux-gnueabi version also needed fixing - to add a -mfloat-abi-soft but that's unnecessary as it's compiled with the gnueabi (not hf) compiler (I've some a quick check that the libc.a produced doesn't include VFP instructions). r? @alexcrichton

…s-message, r=zackmdavis Fix private_no_mangle_fns message grammar Simply changes "an warning" to "a warning" in the `private_no_mangle_fns` warning. I started getting this in some code after upgrading to 1.31.0.
…osure-using-region-from-containing-fn, r=nikomatsakis Add test of current behavior (infer free region within closure body) This behavior was previously not encoded in our test suite. it is pretty important that we test this behavior. In particular, in rust-lang#56537 I had proposed expanding the lifetime elision rules so that they would apply to some of the cases encoded in this test, which would cause them to start failing to compile successfully (because the lifetime attached to the return type would start being treated as connected to the lifetime on the input parameter to the lambda expression, which is explicitly *not* what the code wants in this particular case). In other words, I am trying to ensure that anyone who tries such experiments with lifetime elision in the future quickly finds out why we don't support lifetime elision on lambda expressions (at least not in the naive manner described on rust-lang#56537).

Allow ptr::hash to accept fat pointers Fat pointers implement Hash since rust-lang#45483. This is a follow-up to rust-lang#56250.

… r=kennytm Add short emoji status to toolstate updates I get a lot of these emails and it's good to know which ones I should be paying closer attention to -- i.e. the ones where clippy breaks. This adds a short emoji status report to the first line of the commit message, which shows up in notifications directly I haven't been able to test it, and the actual emoji are just suggestions. r? @kennytm cc @rust-lang/infra @rust-lang/devtools

Bootstrap: Add testsuite for compiletest tool
This adds a test suite for compiletest so that the tester is tested, too.
The (currently) single unit test of the compiletest tool was never executed
on CI. At least I couldn't find any references of it in the logs.
The compiletest tests can then also be executed with:
./x.py test src/tools/compiletest --stage 0

Fixes broken links Just a few broken links. Not sure what to do about this one: https://github.com/rust-lang/rust/blame/master/src/doc/unstable-book/src/language-features/plugin.md#L135 (regex macros were removed a while ago in rust-lang/regex@0375954).
Fix docs path to PermissionsExt Couldn't test the link yet, since I didn't figure out how to build std rustdocs without building the entire compiler itself 🙂
