bors 168a020900 Auto merge of #92686 - saethlin:unsafe-debug-asserts, r=Amanieu ... Add debug assertions to some unsafe functions As suggested by https://github.com/rust-lang/rust/issues/51713 ~~Some similar code calls `abort()` instead of `panic!()` but aborting doesn't work in a `const fn`, and the intrinsic for doing dispatch based on whether execution is in a const is unstable.~~ This picked up some invalid uses of `get_unchecked` in the compiler, and fixes them. I can confirm that they do in fact pick up invalid uses of `get_unchecked` in the wild, though the user experience is less-than-awesome: ``` Running unittests (target/x86_64-unknown-linux-gnu/debug/deps/rle_decode_fast-04b7918da2001b50) running 6 tests error: test failed, to rerun pass '--lib' Caused by: process didn't exit successfully: `/home/ben/rle-decode-helper/target/x86_64-unknown-linux-gnu/debug/deps/rle_decode_fast-04b7918da2001b50` (signal: 4, SIGILL: illegal instruction) ``` ~~As best I can tell these changes produce a 6% regression in the runtime of `./x.py test` when `[rust] debug = true` is set.~~ Latest commit (6894d559bd) brings the additional overhead from this PR down to 0.5%, while also adding a few more assertions. I think this actually covers all the places in `core` that it is reasonable to check for safety requirements at runtime. Thoughts?		2022-04-03 16:04:47 +00:00
