This shows one small benefit of separating `BcbCounter` from `CoverageKind`.
The function source hash will be the same for all counters within a function,
so instead of passing it through `CoverageCounters` and storing it in every
counter, we can just supply it during the final conversion to `CoverageKind`.
rustdoc: Add lint `redundant_explicit_links`
Closes#87799.
- Lint warns by default
- Reworks link parser to cache original link's display text

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.
`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
It's much more complicated than it needs to be, and it doesn't modify
the expression. We can do the `Result` handling outside of it, and
change it to just return a span.
Also fix an errant comma that makes the comment hard to read.
Speed up compilation of `type-system-chess`
[`type-system-chess`](https://github.com/rust-lang/rustc-perf/pull/1680) is an unusual program that implements a compile-time chess position solver in the trait system(!) This PR is about making it compile faster.

Revert PR #114052 to fix invalid suggestion
This PR reverts https://github.com/rust-lang/rust/pull/114052 to fix the invalid suggestion produced by the PR.
Unfortunately the invalid suggestion cannot be improved from the current position where it's emitted since we lack enough information (is an assignment?, left or right?, ...) to be able to fix it here. Furthermore the previous wasn't wrong, just suboptimal, contrary to the current one which is just wrong.
Added a regression test and commented out some code instead of removing it so we can use it later.
