The eventual goal is to try using this for things like the internal panicking stuff, to see whether it helps.
A pointer to address cast are often special-cased. Introduce a dedicated cast kind to make them easy distinguishable.
It returns the previous work product or panics if there is none. This rename makes the purpose of this method clearer.
This improves clarity of the code a bit
A WorkProduct without a saved file is useless
Add support for emitting functions with `coldcc` to LLVM The eventual goal is to try using this for things like the internal panicking stuff, to see whether it helps.

There are still two failures due to incorrect test annotations
And likewise for the `Const::val` method. Because its type is called `ConstKind`. Also `val` is a confusing name because `ConstKind` is an enum with seven variants, one of which is called `Value`. Also, this gives consistency with `TyS` and `PredicateS` which have `kind` fields. The commit also renames a few `Const` variables from `val` to `c`, to avoid confusion with the `ConstKind::Value` variant.
This fixes a couple of potential miscompilations. None affect cg_clif on x86_64, but one may affect cg_clif on AArch64.
Cranelift started depending on a couple of new crates
Using `F_KINFO` fcntl flag, the kf_structsize field needs to be set beforehand for that effect.
…imulacrum Implement `fs::get_path` for FreeBSD. Using `F_KINFO` fcntl flag, the kf_structsize field needs to be set beforehand for that effect.
…smatch, r=cjgillot Slightly improve mismatched GAT where clause error This makes the error reporting a bit more standardized between `where` on GATs and functions. cc rust-lang#99206 (`@BoxyUwU),` don't want to mark this as as "fixed" because they're still not perfect, but this is still an improvement IMO so I want to land it incrementally. regarding "consider adding where clause to trait definition", we don't actually do that for methods as far as i can tell? i could file an issue to look into that maybe.
…ct-field, r=compiler-errors Suggest removing the tuple struct field for the unwrapped value fixes rust-lang#99416
…t-infcx, r=lcnr Remove some explicit `self.infcx` for `FnCtxt`, which already derefs into `InferCtxt` The use of `self.infcx.method_on_infcx` vs `self.method_on_infcx` when `self` is a `FnCtxt` is a bit inconsistent, so I'm moving some `self.infcx` usages I found to just use autoderef
Remove reachable coverage without counters
Remove reachable coverage without counters to maintain invariant that
either there is no coverage at all or there is a live coverage counter
left that provides the function source hash.
The motivating example would be a following closure:
```rust
let f = |x: bool| {
debug_assert!(x);
};
```
Which, with span changes from rust-lang#93967, with disabled debug assertions,
after the final CFG simplifications but before removal of dead blocks,
gives rise to MIR:
```rust
fn main::{closure#0}(_1: &[closure@a.rs:2:13: 2:22], _2: bool) -> () {
debug x => _2;
let mut _0: ();
bb0: {
Coverage::Expression(4294967295) = 1 - 2;
return;
}
...
}
```
Which also makes the initial instrumentation quite suspect, although
this pull request doesn't attempt to address that aspect directly.
Fixes rust-lang#98833.
