This has the nice side-effect of eliminating `rustc_codegen_ssa`'s dependency on `rustc_query_system`. (Indeed, looking through such dependencies was how I found this.)
…ukang coverage: Add a test case for a previously-unknown span mismatch - This is a revised version of rust-lang#152036. --- In rust-lang#145643, a defensive check was added to detect spans that unexpectedly don't match the context of the function body span. There was no known way to trigger that condition, so a `debug_assert!` was added to make violations easier to notice. A way to trigger the condition using nested macro expansions was subsequently found and reported as an ICE (in debug-assertion builds) in rust-lang#147339. Now that we have a concrete example to investigate, we can remove the `debug_assert!` so that there is no ICE in debug-assertion builds. - Fixes rust-lang#147339. r? chenyukang
…BoxyUwU Forbid manual `Unpin` impls for structurally pinned types Part of [`pin_ergonomics`](rust-lang#130494). It forbids to `impl Unpin for T` where `T` is an ADT marked with `#[pin_v2]`.
…yUwU Check proj's parent is trait or not when checking dyn compatibility Fixes rust-lang#151708 When checking dyn compatibility, `proj` here may point to free const whose parent is not trait. Then `TraitRef::from_assoc` will call `generics_of` on the wrong parent. After this change, the following case without `#[type_const]` will still emit ICE same to rust-lang#149066, but different to the ICE reported in rust-lang#151708 ```rust #![feature(min_generic_const_args)] // #[type_const] const N: usize = 2; trait CollectArray { fn inner_array(&self) -> [i32; N]; } ``` r? @BoxyUwU
…anBrouwer Port `rustc_mir` to attribute parser Tracking issue: rust-lang#131229
…r=BoxyUwU error on unsized AnonConsts The constant evaluator does not support unsized types, however, unsized AnonConsts were never checked to be Sized, so no errors were generated on them and the constant was attempted to be constant evaluated. This caused the constant evaluator to ICE. Add a special case for AnonConsts in rustc_hir_typeck, as suggested by @BoxyUwU in rust-lang#137582. There is no checking for `#![feature(unsized_const_params)]` which should eventually revert this check when the feature becomes more implemented. That issue is assigned to @el-ev but I started looking into this as a jumping off point / motivation to learn some compiler stuff, and I eventually got to the point of fixing it, so I'm submitting a PR anyway. So just a ping/FYI to @el-ev that I'm submitting this, sorry! There are three relevant github issues to this ICE that I could find: - fixes rust-lang#137582 - fixes rust-lang#151591 The similar issue rust-lang#104685 is NOT fixed, it might be good to glance at that before verifying this particular fix, to make sure this fix is actually in the right place. (I haven't looked at it much) r? @BoxyUwU
…-derives, r=Zalathar `NativeLib` cleanups Improvements to `NativeLib`. r? @Zalathar
…-Simulacrum disable socket tests in Miri rust-lang#150428 added some tests that do not work in Miri since we do not support sockets. r? @Mark-Simulacrum
