Matthias Krüger 9adf2189f5 Rollup merge of #137449 - compiler-errors:control-flow, r=Amanieu,lnicola ... Denote `ControlFlow` as `#[must_use]` I've repeatedly hit bugs in the compiler due to `ControlFlow` not being marked `#[must_use]`. There seems to be an accepted ACP to make the type `#[must_use]` (https://github.com/rust-lang/libs-team/issues/444), so this PR implements that part of it. Most of the usages in the compiler that trigger this new warning are "root" usages (calling into an API that uses control-flow internally, but for which the callee doesn't really care) and have been suppressed by `let _ = ...`, but I did legitimately find one instance of a missing `?` and one for a never-used `ControlFlow` value in #137448. Presumably this needs an FCP too, so I'm opening this and nominating it for T-libs-api. This PR also touches the tools (incl. rust-analyzer), but if this went into FCP, I'd split those out into separate PRs which can land before this one does. r? libs-api `@rustbot` label: T-libs-api I-libs-api-nominated		2025-03-17 16:34:47 +01:00
