Document Kvasir option --dyncomp-unhandled-ops by mernst · Pull Request #894 · codespecs/daikon

mernst · 2026-10-10T18:56:22Z

Documents the new Kvasir option --dyncomp-unhandled-ops=panic|warn, added in codespecs/fjalar#85, in the Daikon manual and the changelog.

Merge this after codespecs/fjalar#85.

This replaces #891, which GitHub closed when its branch was renamed to match the branch of codespecs/fjalar#85.

📝 Walkthrough

Walkthrough

The changelog and Kvasir options guide document --dyncomp-unhandled-ops=panic and --dyncomp-unhandled-ops=warn. The guide describes how each policy handles unhandled VEX IR operations and the comparability approximation used in warn mode.

Suggested reviewers: markro49

Priority: ⬇️ Low

Change: Other

Merge Risk: 🔵 Low · up to e2c81

Users may see an unresolved release date and receive inaccurate guidance about comparisons mode and unary fallback support. The impact is bounded to documentation and dependency instructions; correct these before relying on the guide.

### Architecture Summary

Architecture risk: 🔵 Low · up to e2c81

The change affects 1 system.

Review details

Systems and components

observed — doc (service) was modified; 2 changed files map to changed impact.

Before / after behavior

observed — Modified behavior in doc/CHANGELOG.md: Adds the Version 5.9.1 changelog entry and documents --dyncomp-unhandled-ops=warn: on an unhandled VEX IR operation, DynComp warns and continues instead of stopping.
observed — Modified behavior in doc/daikon.texinfo: Documents the panic and warn policies for unhandled Valgrind VEX IR operations. The default panic policy prints the operation name and stops; warn reports each operation on first encounter and continues, making a unary result comparable to its operand or making multiple operands mutually comparable. The documentation notes that this approximation may produce comparability sets larger than necessary, but not smaller.

Review comments at @doc/CHANGELOG.md:
- Line 24: Update the Version 5.9.1 heading in the changelog to use the
September 1, 2026 release date instead of the unresolved placeholder, matching
the date recorded in the daikon.texinfo release documentation.

Review comments at @doc/daikon.texinfo:
- Line 4704: Qualify the multi-operand comparability statement in the
documentation so it notes that the binary-operation fallback does not merge
operand tags when --dyncomp-interactions=comparisons is active.
- Line 4703: Update the unary fallback documentation near the
operation-with-one-operand statement to require a Fjalar revision containing PR
#87 and its dependencies, rather than relying only on PR #85; alternatively,
remove the unary fallback claim until that prerequisite is available.

@itemx

… FloatTest use of the option The manual now describes when ternary and quaternary operators skip the check, the exact rule for treating a boolean-producing operator as a comparison, and the behavior under --dyncomp-interactions=none. It uses @itemx for the extra lines of a multi-line @item. FloatTest no longer passes =warn, which hid unhandled operators and required an unmerged Kvasir change.
