Make RawVec private to alloc #90542

the8472 · 2021-11-03T19:52:50Z

RawVec was previously exposed for compiler-internal use (libarena specifically) in 1acbb0a

Since it is unstable, doc-hidden and has no associated tracking issue it was never meant for public use. And since
it is no longer used outside alloc itself it can be made private again.

Also remove some functions that are dead due to lack of internal users.

Finished benchmarking commit (1b12d01): comparison url.

Summary: This change led to very large relevant mixed results 🤷 in compiler performance.

Very large improvement in instruction counts (up to -5.1% on incr-unchanged builds of inflate)
Large regression in instruction counts (up to 4.0% on incr-unchanged builds of deep-vector)

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Next Steps: If you can justify the regressions found in this perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please open an issue or create a new PR that fixes the regressions, add a comment linking to the newly created issue or PR, and then add the perf-regression-triaged label to this PR.
