Don't require `alloca`s for consuming simple enums #138582

scottmcm · 2025-03-16T23:53:51Z

Well, 4 months later I'm finally back to this.

For example, if you pass an Option<u32> to a function, don't immediately write it to an alloca then read it again.

Don't require `alloca`s for creating or consuming simple enums This lets, for example, `Option<u32>` stay a `ScalarPair` the whole time, never needing to get written to stack.

Overall result: ❌✅ regressions and improvements - please read the text below

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

Ah, there we go. Hypothesis confirmed: I stopped using this path for anything reading a Scalar::Initialized from a Scalar::Union. Quite a powerful demonstration of the importance of noundef, I guess. Nice to see it still saves some binary size in opt too.

I'll see if I can tweak things a bit more to make it more obviously neutral-or-better, but at least it's already cycle-neutral.
