Run mir-opt panic=abort tests on CI by Kobzol · Pull Request #160200 · rust-lang/rust

Kobzol · 2026-07-30T07:54:21Z

Context: https://rust-lang.zulipchat.com/#narrow/channel/131828-t-compiler/topic/Blessing.20mir-opt.20on.20a.20clean.20checkout.20produces.20a.20diff/near/613465816

It looks like we didn't run them on CI (ever? lol).

RalfJung is not on the review rotation at the moment.
They may take a while to respond.

I don't know nearly enough about bootstrap to review this.^^
@rustbot reroll

RalfJung · 2026-07-30T08:34:28Z

+        // Now also run the tests for the host with panic=abort
+        let panic_abort_target = builder
+            .ensure(MirOptPanicAbortSyntheticTarget { compiler: self.compiler, base: self.target });
+        run(panic_abort_target);


This will be redundant with --bless I think?
mir-opt --bless already takes very long due to all the sysroots it is building, I'd prefer it not to become even slower.

View changes since the review

It is only redundant if the host target matches the hardcoded targets we have below. I can add an if condition to skip them if they match the host target.

That being said, if the stdlib it built, re-running the tests again should be very fast, they will just be ignored.

It is always redundant. There are only 4 actually distinct configurations, so running more than 4 targets on --bless is redundant.

I see, so the target doesn't really matter, the only thing that matters is bitwidth and the panic strategy? Yeah, in that case I will try to optimize it to always run 2 targets when not blessing, and 4 targets when blessing.

Yeah.

When checking it's good to check the actual self.target to ensure CI covers them all. But in principle only the bitwidth and panic strategy should matter.

RalfJung · 2026-07-30T08:42:18Z

The existing behavior of --bless is kind of annoying since it takes so long to build all these sysroots... and it actually builds 5 sysroots when 4 should be enough. (With this PR as-is it'd become 6 sysroots!) Not sure if there is something we could improve there. Does bootstrap know whether self.target is a 32bit target or 64bit target? If yes, we could bless

current target
current target with panic=abort
target of other bitwidth
target of other bitwidth with panic=abort

And only run the first two steps for non-bless mode. That'd be nice.

Kobzol · 2026-08-07T07:28:14Z

And only run the first two steps for non-bless mode. That'd be nice.

But when we do the check, we should test all 4 combinations, right? Otherwise we could get back into the same problem, where some of the combinations are not checked on CI, and thus bless becomes "dirty".

RalfJung · 2026-08-07T07:30:57Z

We are running mir-opt tests on all tier 1 targets, right? So 32bit and 64bit are both covered.

Kobzol · 2026-08-07T07:32:05Z

Ah, I see, makes sense. Thanks.

Kobzol · 2026-08-07T08:24:41Z

Ok, I refactored the whole thing. Now when checking, we run the current target, and then the current target with the "inverted" panic strategy. And when blessing, we run the current target + four fixed targets, as before (there was a comment saying that running also the current target when blessing is desired).

It is now possible to create synthetic targets with both panic abort/unwind strategies, and the generated miropt test steps are now created as separate step instances, which means that they will be more explicit tin the step trace, and they will also be properly cached.

RalfJung · 2026-10-28T12:51:21Z

This also improves ./x test mir-opt --bless, right? It makes it 20% faster by only running for 4 targets rather than 5? Would it make sense to land that part separately?

And only include the target name when rendering test metadata, to avoid including filenames in it. # Conflicts: # src/bootstrap/src/core/builder/tests.rs

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

Kobzol · 2026-11-07T15:11:54Z

We could, I suppose. It would in general be much easier if we could just test the 4 pinned targets, rather than trying to make all CI targets work here. Let's try again.
