  thread 'main' has overflowed its stack

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]

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]

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]

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

[CryZe]

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

[CryZe]

The regression happened between nightly-2024-06-28 (working) and nightly-2024-06-29 (broken), which puts the regression in the following range:
rust-lang/rust@9c3bc80...e9e6e2e

[CryZe]

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

[CryZe]

I was able to reproduce it locally and run cargo bisect-rustc on it. The regression is in rust-lang/rust@99f77a2 which is rust-lang/rust#127076

[alexcrichton]

Thanks for investigating! Nothing obvious there and my hunch would be rust-lang/rust#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]

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]

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?

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.
