@Patrick-6 You said we need cc 1.2.30, but that's not correct, is it? flags was added in rust-lang/cc-rs@f50ff26 which is included in 1.2.22.

And it seems we could easily avoid it by just calling flag in a loop so maybe we should do that.

jieyouxu · 2025-07-28T08:13:07Z

The comment indicates that "not having the same cc version in both crates" causes breakage. But you seem to say that just using a newer cc causes breakage? Then I misread the comment.

Wait sorry, you meant that the cc version must be sync'd between the compiler crates?

RalfJung · 2025-07-28T08:13:55Z

@jieyouxu that's what I thought the comment meant. I guess it means something else.

RalfJung · 2025-07-28T08:15:54Z

I have updated the comment.

@jieyouxu can we just rely on PR CI catching these cc issues, or should we try-build some extra targets, or should we do some work on the Miri side to avoid bumping cc?

RalfJung · 2025-07-28T08:17:10Z

compiler/rustc_codegen_ssa/Cargo.toml

-cc = "=1.2.16"
+# `cc` updates often break things, so we pin it here. Cargo enforces "max 1 semver-compat version
+# per crate", so if you change this, you need to also change it in `rustc_llvm`.
+cc = "=1.2.30"


FWIW, we could just remove the pin here and rely on rustc_llvm pinning the version for the entire workspace... 🤷

@jieyouxu can we just rely on PR CI catching these cc issues, or should we try-build some extra targets, or should we do some work on the Miri side to avoid bumping cc?

I think it's easiest to just try full CI

jieyouxu · 2025-07-28T08:36:48Z

The cc versions were pinned because new versions often caused build breakages, i.e. they couldn't be bumped. If we can bump them, great.

Another reason why cc is pinned is so that breakages from cc updates don't prevent the weekly cargo update bumps from being able to take place, I think?
