@WG-prioritization/alerts issue #80268 has been requested for prioritization.

Procedure

Camelid (Dec 21 2020 at 22:27, on Zulip):

Not sure if we should prioritize this, but seems pretty weird.

apiraino (Dec 23 2020 at 14:07, on Zulip):

I don't understand too well the story here. What does the sample provided shows? An llvm issue? @Léo Lanteri Thauvin what do you think about this?

Léo Lanteri Thauvin (Dec 23 2020 at 14:07, on Zulip):

I'm confused :D

apiraino (Dec 23 2020 at 14:08, on Zulip):

lol me too

apiraino (Dec 23 2020 at 14:09, on Zulip):

by the way @Santiago Pastorino this issue does not appear in our filters because it does not have a team label. Should this issue be a T-compiler?

Léo Lanteri Thauvin (Dec 23 2020 at 14:17, on Zulip):

Yeah, I think it should

apiraino (Dec 23 2020 at 14:19, on Zulip):

ok assigning that, so we don't lose it

Camelid (Dec 23 2020 at 20:52, on Zulip):

I don't really understand this one either :)

Léo Lanteri Thauvin (Dec 23 2020 at 20:53, on Zulip):

Maybe ping LLVM? They will know better :D

Camelid (Dec 23 2020 at 20:58, on Zulip):

If we're pretty sure it's an LLVM issue, then maybe.

Léo Lanteri Thauvin (Dec 23 2020 at 21:00, on Zulip):

According to the backtrace the crash happens in LLVM

Léo Lanteri Thauvin (Dec 23 2020 at 21:12, on Zulip):

Pinged LLVM

Santiago Pastorino (Dec 24 2020 at 14:21, on Zulip):

this is pending prioritization

Santiago Pastorino (Dec 24 2020 at 14:22, on Zulip):

it's for a tier 2 platform, so definitely not P-critical

Santiago Pastorino (Dec 24 2020 at 14:23, on Zulip):

@Léo Lanteri Thauvin saw you added and removed, requires-nightly

Santiago Pastorino (Dec 24 2020 at 14:23, on Zulip):

I was wondering exactly about versions and these things, does this requires-nightly? is this a regression?

Léo Lanteri Thauvin (Dec 24 2020 at 16:00, on Zulip):

I thought the asm! was required for the repro, but apparently it wasn't

apiraino (Dec 30 2020 at 14:17, on Zulip):

nothing new about this issue yet. @Santiago Pastorino Should we I-nominate it and ask the team what they think about it? The LLVM group seems to have already been notified

Santiago Pastorino (Dec 30 2020 at 16:11, on Zulip):

unsure, the agenda was very packed last time I saw it

apiraino (Dec 30 2020 at 16:55, on Zulip):

this week's agenda is lighter (also we're very close to a release). After thinking a bit more about I would not nominate it anyway because imo there is not yet enough to reason about this issue

apiraino (Dec 30 2020 at 16:57, on Zulip):

The issue reporter is trying to crosscompile for a tier2 platform (aarch64-unknown-none) manually handling LLVM parameters (iiuc) so I'd like to see more about this.
Also, maybe not relevant, but if that happens also on other targets with other rustc version (i.e. stable)

apiraino (Dec 30 2020 at 17:03, on Zulip):

Like Léo Lanteri Thauvin comment point out, I also feel this is an LLVM issue

Yuki Okushi (Jan 08 2021 at 06:44, on Zulip):

this one isn't prioritized yet (and no updates from LLVM folks)

Yuki Okushi (Jan 08 2021 at 06:45, on Zulip):

Santiago Pastorino said:

The repro needs the build-std feature so it should be require-nightly

Yuki Okushi (Jan 08 2021 at 06:46, on Zulip):

I'm for P-medium

apiraino (Jan 08 2021 at 11:54, on Zulip):

ok for me (I was undecided on this one). eventually we can tune the priority as the triaging progresses
