Add `modulo` and `mod` as doc aliases for `rem_euclid`.
When I was learning Rust I looked for “a modulo function” and couldn’t find one, so thought I had to write my own; it wasn't at all obvious that a function with “rem” in the name was the function I wanted. Hopefully this will save the next learner from that.
However, it does have the disadvantage that the top results in rustdoc for “mod” are now these aliases instead of the Rust keyword, which probably isn't ideal.
Add doc aliases for trigonometry and other f32,f64 methods.
These are common alternate names, usually a less-abbreviated form, for the operation; e.g. `arctan` instead of `atan`. Prompted by <https://users.rust-lang.org/t/64-bit-trigonometry/98599>
`ignore-cross-compile` on `optimization-remarks-dir-pgo` test
We noticed this on our upstream pull on ferrocene a week ago as it was failing our CI. The test attempts to run the produced binary which won't work when cross compiling.

Synchronize with all calls to `unpark` in id-based thread parker
[The documentation for `thread::park`](https://doc.rust-lang.org/nightly/std/thread/fn.park.html#memory-ordering) guarantees that "park synchronizes-with all prior unpark operations". In the id-based thread parking implementation, this is not implemented correctly, as the state variable is reset with a simple store, so there will not be a *synchronizes-with* edge if an `unpark` happens just before the reset. This PR corrects this, replacing the load-check-reset sequence with a single `compare_exchange`.
Clearly the code path can be hit without the presence of a compiler bug.
All it takes is mischief. See 71698.
Ignore problematic directories instead of ICE:ing. `continue`ing is
already done for problematic dirs in the code block above us.
minor : Deunwrap generate_derive
#15398 subtask 1. Since the editing closure has arms, I did something *experimental* ( in this case just a clever term for bad code ) to bypass creating an `Option` but I am ready to change this.
`Nonterminal`-related cleanups
In #114647 I am trying to remove `Nonterminal`. It has a number of preliminary cleanups that are worth merging even if #114647 doesn't merge, so let's do them in this PR.
r? `@petrochenkov`
Otherwise the file name generated for generator_drop will become
core.ptr-drop_in_place.[generator@<FILEPATH>_<NUMBERS>].generator_drop.0.mir
instead of main-{closure#0}.generator_drop.0.mir which breaks a mir-opt
test.
Replace the \01__gnu_mcount_nc to LLVM intrinsic for ARM
Current `-Zinstrument-mcount` for ARM32 use the `\01__gnu_mcount_nc` directly for its instrumentation function.
However, the LLVM does not use this mcount function directly, but it wraps it to intrinsic, `llvm.arm.gnu.eabi.mcount` and the transform pass also only handle the intrinsic.
As a result, current `-Zinstrument-mcount` not work on ARM32. Refer: https://github.com/namhyung/uftrace/issues/1764
This commit replaces the mcount name from native function to the LLVM intrinsic so that the transform pass can handle it.
[RFC-3086] Restrict the parsing of `count`
Fix#111904
The original RFC didn't mention the possibility of using `${count(t,)}` and such thing isn't very semantically accurate which can lead to confusion.
Normalize before checking if local is freeze in `deduced_param_attrs`
Not normalizing the local type eagerly results in possibly exponential amounts of normalization happening downstream in `is_freeze_raw`.
Fixes#113372
