Parser: Document restrictions
I had trouble easily understanding what these various flags do. This is my attempt to try to explain what these do.

rustfmt: Also allow bool literals as first item of let chain
This is a functional cherry-pick of https://github.com/rust-lang/rustfmt/pull/6492
I'm bringing this change over directly as the subtree sync is taking more effort than anticipated (some unrelated r-l/rustfmt changes need to be reverted before we perform the full sync) and we need to ensure that rustfmt behavior accounts with the final style guide rules as part of let chain stabilization.

Require sanitizers be enabled for asan_odr_windows.rs
Issue Details:
The `asan_odr_windows.rs` test is failing on AArch64 Windows, as sanitizers aren't supported on that platform.
Fix Details:
Apply the correct "need sanitizer" requirements to the test.

Don't FCW assoc consts in patterns
Fixes #140447
See comment in added test. We could also check that the anon const is a const arg by looking at the HIR. I'm not sure that's necessary though :thinking: The only consts that are evaluated "for the type system" are const args (which *should* get FCWs) and const patterns (which cant be anon consts afaik).

chore: edit and move tests
I deleted `ui/non-copyable-void.rs`: added in https://github.com/rust-lang/rust/commit/ab4105d9e8b7c0719343aa2e4edd15cae0b7c947 to test that "nonconstructable" enums are "noncopyable", but these properties are not correlated anymore.
Second commit is kinda messy because I moved/edited/renamed some files at the same time, but I deleted nothing there.

Replace use of rustc_type_ir by rustc_middle
cc #138449
I want to help on this issue. I have replaced all the rustc_type_ir uses by the equivalent type in rustc_middle.
DelayedSet is also re-exposed by rustc_middle.

Fixes #118860. The compile time was addressed earlier, this merely addresses stack overflow part of the issue.

Issue an error when using `no_mangle` on language items
This pull requests adds the code to issue an error or a warning when using `no_mangle` on language items. This should detail why the `undefined symbol` error is issued for the code described in #139923.
The pull request adds two ui tests, one testing the error and the other one the warning.
I would love some feedback here, as I am not sure that the error and warning are issues using the right API.

Don't allow flattened format_args in const.
Fixes https://github.com/rust-lang/rust/issues/139136
Fixes https://github.com/rust-lang/rust/issues/139621
We allow `format_args!("a")` in const, but don't allow any format_args with arguments in const, such as `format_args!("{}", arg)`.
However, we accidentally allow `format_args!("hello {}", "world")` in const, as it gets flattened to `format_args!("hello world")`.
This also applies to panic in const.
This wasn't supposed to happen. I added protection against this in the format args flattening code, ~~but I accidentally marked a function as const that shouldn't have been const~~ but this was removed in https://github.com/rust-lang/rust/pull/135139.
This is a breaking change. The crater found no breakage, however.
This breaks things like:
```rust
const _: () = if false { panic!("a {}", "a") };
```
and
```rust
const F: std::fmt::Arguments<'static> = format_args!("a {}", "a");
```

Share the naked asm impl between cg_ssa and cg_clif
This was introduced in https://github.com/rust-lang/rust/pull/128004.
|
|
This commit does the following:
- Replaces use of rustc_type_ir by rustc_middle
- Removes the rustc_type_ir dependency
- The DelayedSet type is exposed by rustc_middle so everything can be
accessed through rustc_middle in a coherent manner.

Rename `rustc_query_append!` to `rustc_with_all_queries!`
Whenever I'm trying to make sense of the query system internals, I always get tripped up on this unhelpfully-named macro. The fact that it's a higher-order proc macro is already mind-melting enough on its own.
This new name, `rustc_with_all_queries!`, forms a much more intuitive combination with the helper macros that it invokes. And only one of the call sites was even making use of the “append” part of its old name.
This PR also reformats the parameters matched by the helper macros, to make the actual argument syntax a bit easier to see.
---
Renaming and reformatting only; no functional changes.

Add `rust.debug-assertions-tools` option
Before this PR, the two only options to configure the presence of debug assertions were the `rust.debug-assertions` and `rust.debug-assertions-std` options. The former applied to everything, and the latter allowed to override the setting just for the standard library. This combination of settings doesn't allow to enable debug assertions for the std and the compiler but not tools.
Some tools (like Cargo) are not really meant to be executed with debug assertions enabled, and in Ferrocene we hit some debug assertions in it that are exclusively meant for its test suite. We'd thus like to enable debug assertions everywhere but in tools.
This PR adds a `rust.debug-assertions-tools` setting that does exactly this.

rm `TypeVistable` impls for `Canonical`
similar to `EarlyBinder`, you generally do not want to fold a canonical value directly without first instantiating it. In places where you do want to look into the `Canonical`, it's likely better to do so manually.

Remove backticks from `ShouldPanic::YesWithMessage`'s `TrFailedMsg`
More legible imo
```rs
#[test]
#[should_panic = "love"]
fn foo() {
assert!(1 == 2);
}
```
Before:
```
note: panic did not contain expected string
panic message: `"assertion failed: 1 == 2"`,
expected substring: `"love"`
```
After:
```
note: panic did not contain expected string
panic message: "assertion failed: 1 == 2"
expected substring: "love"
```
Also removed the comma as `assert_eq!` / `assert_ne!` don't use one.
