Rust Compiler Performance Triage

Largely a positive week despite taking a significant performance hit from turning on incremental compilation verification for a subsection of the total queries that the compiler does in order to more quickly catch bugs in incremental compilation. Luckily optimizations in bidi detection brought large performance improvements.

Triage done by @rylev. Revision range: 6384dc..eee8b

2 Regressions, 4 Improvements, 4 Mixed; 1 of them in rollups 45 comparisons made in total

Quote of the Week

And even if you could fix all of rustc's soundness holes, or otherwise prevent user code from exploiting them, a soundness bug in any third-party library can also make it possible for malicious crates to trigger arbitrary behavior from safe code.

[...]

This is why we need to emphasize that while Rust's static analyses are very good at limiting accidental vulnerabilties in non-malicious code, they are not a sandbox system that can place meaningful limits on malicious code.
