### bugs fixed:
- glob failed to match broken symlinks consistently

### arch-specific bugs fixed:
- x87 floating point stack imbalance in math asm (i386-only CVE-2019-14697)
- x32 clock_adjtime, getrusage, wait3, wait4 produced junk (struct mismatches)
- lseek broken on x32 and mipsn32 with large file offsets
- riscv64 atomics weren't compiler barriers
- riscv64 atomics had broken asm constraints (missing earlyclobber flag)
- arm clone() was broken when compiled as thumb if start function returned
- mipsr6 setjmp/longjmp did not preserve fpu register state correctly
Fixes#71099.
x.py: do not build Miri by default on stable/beta
Fixes https://github.com/rust-lang/rust/issues/73117
Do I need to do anything to make sure Miri is still built by the tools CI builder? Are there other tools that should be off-by-default?
Also, unfortunately the `DEFAULT` associated const has no doc comment, so I have no idea what it does, or why there are semmingly two places where the default build of tools is controlled.

Adjusted some doctests in libcore to use `should_panic`.
Fixes#73196 .
I grepped libstd and libcore for all the instances of this pattern that I could find, but its possible that I missed some of course. If anyone knows of any more, please let me know and I will add them to the PR.
Use the built cargo for cargotest.
cargotest was using the beta (bootstrap) cargo. This changes it so that it will use the locally built cargo. This is intended to provide a sort of smoke test to ensure Cargo is functional. This *shouldn't* have any real impact on the CI build time. The cargotest job also happens to run cargo's testsuite, so it should already be building cargo.
Note: This will fail until #73266 is merged.
Querify whether a type has structural equality (Take 2)
Alternative to #72177.
Unlike in #72177, this helper method works for all types, falling back to a query for `TyKind::Adt`s that determines whether the `{Partial,}StructuralEq` traits are implemented.
This is my preferred interface for this method. I think this is better than just documenting that the helper only works for ADTs. If others disagree, we can just merge #72177 with the fixes applied. This has already taken far too long.
Clarify the behaviour of Pattern when used with methods like str::contains
Fixes#45507.
I used the previous work by @Emerentius (thanks !), added a paragraph and checked the links (they work for me but I'm not against someone else checking them too).
These lead to inference regressions (mostly in tests) in code that looks
like:
let socket = std::net::SocketAddrV4::new(std::net::Ipv4Addr::new(127, 0, 0, 1), 8080);
assert_eq!(socket, "127.0.0.1:8080".parse().unwrap());
That compiles as of stable 1.44.0 but fails in beta with:
error[E0284]: type annotations needed
--> src/main.rs:3:41
|
3 | assert_eq!(socket, "127.0.0.1:8080".parse().unwrap());
| ^^^^^ cannot infer type for type parameter `F` declared on the associated function `parse`
|
= note: cannot satisfy `<_ as std::str::FromStr>::Err == _`
help: consider specifying the type argument in the method call
|
3 | assert_eq!(socket, "127.0.0.1:8080".parse::<F>().unwrap());
|
Previously, some doctests were spawning new threads and joining them to
indicate that a particular call should panic; this hurt readability, so
the tests have been adjusted to simply call the method and use the
`should_panic` marker.
This helper method works for all types, falling back to a query for
`TyKind::Adt`s to determine whether the implement the
`{Partial,}StructuralEq` traits.
Allow inference regions when relating consts
As first noticed by @eddyb, `super_relate_consts` doesn't need to check for inference vars since `eval` does it already (and handles lifetimes correctly by erasing them).
Fixes#73050
r? @oli-obk
expand: More precise locations for expansion-time lints
First commit: a macro expansion doesn't have a `NodeId` associated with it, but it has a parent `DefId` which we can use for linting.
The observable effect is that lints associated with macro expansions can now be `allow`ed at finer-grained level than whole crate.
Second commit: each macro definition has a `NodeId` which we can use for linting, unless that macro definition was decoded from other crate.
