2022-11-01Rollup merge of #103781 - JakobDegen:mir-opt-tidy, r=jyn514Manish Goregaokar-404/+0
Detect unused files in `src/test/mir-opt` and error on them in tidy. Closes #97564 . Determining which files are generated by a given mir opt test is somewhat difficult. Because of this, we extract the logic for doing it out into a common crate that both compiletest and tidy can depend on. This avoids making compiletest a dependency of tidy which would negatively impact compile times for tidy. Testing for this is that it catches 5 files that violated this lint (and removes them).

2022-10-08Rollup merge of #102778 - nbdd0121:mir, r=tmiaskoMatthias Krüger-0/+67
Fix MIR inlining of asm_unwind The MIR inlining currently doesn't handle inline asm's unwind edge correctly. This code will cause ICE: ```rust struct D; impl Drop for D { fn drop(&mut self) {} } #[inline(always)] fn foo() { let _d = D; unsafe { std::arch::asm!("", options(may_unwind)) }; } pub fn main() { foo(); } ``` This PR fixes this issue. I also take the opportunity to extract common code into a method.

Remove `mir::CastKind::Misc` As discussed in #97649 `mir::CastKind::Misc` is not clear, this PR addresses that by creating a new enum variant for every valid cast. r? ````@oli-obk````

Always print '_, even for erased lifetimes. Explicit lifetime arguments are now the recommended syntax in rust 2018 and rust 2021. This PR applies this discipline to rustc itself.

fix ConstProp handling of written_only_inside_own_block_locals Fixes a regression introduced by https://github.com/rust-lang/rust/pull/100239, which adds an early return and thus skips some code in `visit_terminator` that must be run for soundness.
