Bump `COINDUCTIVE_OVERLAP_IN_COHERENCE` to deny + warn in deps #116493

compiler-errors · 2023-10-06T19:47:57Z

1.73 is the first place this shows up in stable (recall that there was only 1 regression), so let's bump this to deny on nightly.

lcnr · 2023-10-07T07:56:44Z

cc #114040 I would like to stabilize the new solver with inductive cycles set to ambiguity, so linting this more strongly for the remaining few months until stablization feels useful to me.

@rfcbot fcp merge

rfcbot · 2023-10-07T07:56:46Z

Team member @lcnr has proposed to merge this. The next step is review by the rest of the tagged team members:

No concerns currently listed.

Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

See this document for info about what commands tagged team members can give me.

Didn't change behavior at all.

Yup agreed this is noise: all these returned to their steady state in #116402 (comment).

Pkgsrc changes: * Adjust patches and cargo checksums to new versions. * For an external LLVM, set dependency of llvm >= 16, in accordance with the upstream changes. * Mark that on NetBSD we now need >= 9.0, so 8.x is no longer supported. * On NetBSD/sparc64 10.x, we now need GCC 12 to build the embedded LLVM, which is version 17; apparently GCC 10.4 or 10.5 mis-compiles it, resulting in an illegal instruction fault during the build.
