From 995dcae187c32d36c2191028567964116bcf0b70 Mon Sep 17 00:00:00 2001 From: Jason Gross Date: Tue, 28 Jul 2026 04:30:00 +0000 Subject: [PATCH 1/6] Adapt to Rocq dev: HB `of` clauses, mathcomp Nz* hierarchy, `^*` level Three unrelated breakages against Rocq 9.4+alpha / mathcomp dev: * Rocq now reserves `of` as a keyword (`constructor_binders` in g_vernac.mlg, "Add \"of _ & _ & _\" syntax for constructors"). coq-elpi parses HB's `of` clause as `IDENT "of"`, which no longer matches, so every `HB.mixin Record ... of ...`, `HB.factory Record ... of ...` and `HB.builders Context ... of ...` fails with a bare "Usage:" message. Use the equivalent `&` spelling, which is the form the HB usage message itself documents and works on older versions too. * mathcomp split its ring hierarchy: `SemiRing` no longer carries `1 != 0`, the nontrivial variant is `NzSemiRing`. Rename SemiRing -> NzSemiRing, ComSemiRing -> ComNzSemiRing, isSemiRing -> isNzSemiRing, SubSemiRing -> SubNzSemiRing, SubChoice_isSub[Com]SemiRing -> SubChoice_isSub[Com]NzSemiRing and SubSemiRing_isSubComSemiRing -> SubNzSemiRing_isSubComNzSemiRing, preserving the previous meaning of the dioid structures. * mathcomp's ssrfun now reserves `x ^*` at level 1 with left associativity; match that reservation instead of level 2.

From af4d558249e1334b2ae5ab680e5abc67dedb2e9d Mon Sep 17 00:00:00 2001 From: Jason Gross Date: Tue, 28 Jul 2026 04:36:41 +0000 Subject: [PATCH 2/6] Adapt to the mathcomp 2.6 ssreflect `rewrite (_ : A = B)` goal order MathComp 2.5.0's mathcomp/boot/ssreflect.v carried `Global Set SsrOldRewriteGoalsOrder.`; mathcomp dev (2.6+, PR #1545) removed it, so the Rocq option reverts to its default and the side condition produced by `rewrite (_ : A = B)` is now left as the FIRST goal instead of the last. That is what the `; last first.` idiom in these proofs was compensating for. This is a mathcomp change, not a Rocq one: the flag itself is permanent and undeprecated. Swap the idiom at each of the five affected sites -- drop `; last first.` where it was present and add it where it was not -- leaving the proof scripts themselves untouched. With only five sites this is cheaper than adding a per-file `Set SsrOldRewriteGoalsOrder.`, and it is step (2) of the ladder mathcomp's own 2.6.0 CHANGELOG describes, so it does not have to be undone later. The cost is that the file now requires mathcomp >= 2.6, which the opam bounds state.

That works, but it edits proof scripts to compensate for a flag change, which makes the diff harder to read and harder to carry upstream. Restore all five sites to their upstream form and set the flag once at the top of the file instead. Plain `Set`, deliberately not `Global`/`#[global]`: the option is sticky through Require, so a global setting would silently impose the old goal order on every consumer of complete_dioid.v, including ones that have already migrated. The flag is undeprecated and permanent, so this needs no follow-up; it is step (1) of the ladder mathcomp's own 2.6.0 CHANGELOG describes, and the file can be moved to step (3) -- deleting the line -- whenever the proofs are actually ported to the new order. Verified: make -j8 against Rocq 9.4+alpha builds 3/3 .vo.
