A few small regressions on smaller benchmarks (e.g., helloworld), likely centered around more IR being generated in a few cases.

2 Regressions, 1 Improvements, 0 Mixed

1 of them in rollups

Rollup of 6 pull requests #86417

Moderate regression in instruction counts (up to 2.0% on incr-unchanged builds of helloworld-opt)
Not really clear what the cause here is, but the regression is concentrated on small benchmarks.

Change entry point to 🛡️ against 💥 💥-payloads #86034

Moderate regression in instruction counts (up to 4.5% on incr-full builds of helloworld-opt)
Seems to be more code getting generated into binaries, leading to regressions on the smaller benchmarks.

optimize Eq implementation for paths #86179

Moderate improvement in instruction counts (up to -3.3% on incr-patched: println builds of cargo-opt)
Mostly wins on incremental benchmarks.
