Versions and Environment

Cranelift version or commit: cranelift-codegen v0.104.3 as well as cranelift-codegen v0.109.0

Operating system: Windows

Architecture: x86_64

Rust: x86_64-pc-windows-msvc latest update on 2024-07-08, rust version 1.81.0-nightly (20ae37c18 2024-07-07)

Actually seems to have been happening since at least: latest update on 2024-06-30, rust version 1.81.0-nightly (ba1d7f4a0 2024-06-29) Last time I saw it working was: latest update on 2024-06-24, rust version 1.81.0-nightly (bcf94dec5 2024-06-23)

Extra Info

CryZe commented 4 months ago

This might just be a temporary / general issue with the latest Windows nightly compiler. This does not reproduce on any other target, not even the GNU variant.

alexcrichton commented 4 months ago

Would you be able to run a bisection to determine what caused this? The cargo bisect-rustc subcommand I believe is the go-to tool for this.

CryZe commented 4 months ago

It's pretty late here, I'll look into it tomorrow.

CryZe commented 4 months ago

I was not able to reproduce it outside of the Github Actions, so I'll bisect it there manually now.

CryZe commented 4 months ago

The regression happened between nightly-2024-06-28 (working) and nightly-2024-06-29 (broken), which puts the regression in the following range: https://github.com/rust-lang/rust/compare/9c3bc805d...e9e6e2e44

CryZe commented 4 months ago

The only thing that stands out to me is some changes to LLD and the patchable function entries.

CryZe commented 4 months ago

I was able to reproduce it locally and run cargo bisect-rustc on it. The regression is in https://github.com/rust-lang/rust/commit/99f77a2eda555b50b518f74823ab636a20efb87f which is https://github.com/rust-lang/rust/pull/127076

alexcrichton commented 4 months ago

Thanks for investigating! Nothing obvious there and my hunch would be https://github.com/rust-lang/rust/pull/126970 but even then it's probably a case where we had a really deep stack before and just happened to overflow now.

Since you're able to reproduce locally are you able to capture a backtrace to see where the stack overflow is coming from?

CryZe commented 4 months ago

This is how you can reproduce it (with a sufficiently up to date Windows MSVC nightly toolchain):

cargo +nightly build -p cranelift-codegen --target x86_64-pc-windows-msvc

what's interesting is that this does NOT reproduce it (which is slightly different for cargo in how it's able to reuse dependencies of the host vs. the target):

cargo +nightly build -p cranelift-codegen

Mmmh, that does not look super healthy regardless of whether it's a slight regression.

But I believe you are right. The PR you linked does inline the clone_into function, which possibly got inlined into any of these functions on the stack here, increasing the stack usage a little, which was just enough to push it over the edge.

alexcrichton commented 4 months ago

For ISLE-related folks, does anyone know if this is a bug to have this much recursion between here and here? If so is it possible to somewhat easily make this a loop rather than recursive? If not is there a way to reduce the size of functions to avoid having such a large stack frame?

jameysharp commented 4 months ago

This recursion certainly could be rewritten to use an explicit stack. Its depth is proportional to the number of constraints in the left-hand side of a rule, so I didn't expect it to be a problem.

It would be nice to figure out which rule it was generating code for at the time. (It must be a mid-end optimization rule if Loop is involved.) But I suppose we don't really need to know; presumably we consider all the rules to be of reasonable size so we need ISLE to just handle them.

It's also worth noting that since build scripts are compiled in debug mode, rustc is building this without optimization.

jameysharp commented 4 months ago

@CryZe, could you test whether #8935 fixes this issue for you?

There are several other parts of ISLE which also recurse over the structure of a user-provided rule, so I'm concerned that we may have this problem again in the future. But emit_block is one of the last things to run so I believe all the other recursive functions are currently succeeding. As a result I don't want to change them right now.

CryZe commented 4 months ago

The PR does indeed seem to fix the issue. Thanks for working on it :)

jameysharp commented 4 months ago

I forgot to mark that PR as fixing this, so now that it's merged I'll close this issue.

sunshowers commented 3 months ago

Quite likely related: https://github.com/rust-lang/rust/issues/128422

That's fundamentally a rustc issue, but would this fix work around that?

cfallin commented 3 months ago

@sunshowers I don't think the fix above would address that issue unfortunately -- Jamey's change removes recursion (in favor of iteration with an explicit stack) in the ISLE DSL-to-Rust compiler, but the generated Rust code that causes rust-lang/rust#128422 will be exactly the same. (They're certainly related in the sense that the matcher decision tree gets quite deep!)

sunshowers commented 3 months ago

That makes sense! Thanks @cfallin.
