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.

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.

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

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

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

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

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

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?

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.

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.

ISLE: Make block codegen non-recursive
d9e04b7 
In bytecodealliance#8919 we learned that `Codegen::emit_block` can overrun the stack
when generating Rust source for deeply-nested blocks. Stack usage can be
worse than one might expect because ISLE is called from a build script,
and those are always built in debug mode.

This commit avoids the problem by using an explicit heap-allocated stack
instead of recursion.

I recommend turning on the "ignore whitespace" option in your diff tool
of choice when reviewing this commit.

The amount of stack space that this recursive function uses is affected
by the version of rustc used to compile it, and the amount of stack
space available depends on the host platform. As a result, this was only
observed on Windows with a recent nightly version of rustc, but it could
eventually affect other platforms or compiler versions, especially as
ISLE rules grow in complexity.

Note that there are several other places in ISLE which recurse over the
user-provided rules. This commit does not change those, but they could
also become a problem in the future.

@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.

Quite likely related: rust-lang/rust#128422

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

@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!)
