add regression test for packus_epi16 issue by RalfJung · Pull Request #162341 · rust-lang/rust

RalfJung · 2026-09-05T18:13:01Z

#159464 got fixed without a test. This adds the missing test.

Ideally this would be tested in stdarch, but we don't have enough infrastructure for that. Testing it here is better than not testing it at all.

FYI you can override this by passing nolimit as an argument, the error should probably say that...
I'll make a fix

Yeah I know that, but the docs also said one should only use it when really needed so I didn't dare using it.^^

JonathanBrouwer · 2026-09-06T18:52:24Z

Afaik it's mostly a guard against accidental invocations, where do the docs say that?

RalfJung · 2026-09-06T18:54:28Z

I forgot, I thought I read it somewhere... maybe it was Zulip? #t-infra/announcements > Bors changelog @ 💬

This is designed for rare situations for complex PRs where you want to essentially test everything before landing it (e.g. LLVM updates or complex feature stabilizations). Please use it sparingly.

@folkertdev I think we have to just restrict the test to Linux... does that seem reasonable?

folkertdev · 2026-09-07T04:31:17Z

Yes, that's fine
