🤖 *AI text below* 🤖 ## Description Backport selected changes from `main` to the maintained `v3.x` branch in preparation for MQT Core 3.8.0. The commits are kept separate by upstream change wherever practical. The series includes: - configurable QDMI device discovery and stable-ID registration from #1912 - binary-safe FoMaC/QDMI program handling from #1957 - CMake subproject composability and individually selectable bundled QDMI devices from the current #1965 head (`cdc740398e472c19b585cf6dbd7d41de053d84a6`) - optional QIR support for the DDSIM QDMI device and the associated QIR runtime improvements - native RCCX support and the bottom-up DD construction path - Python CI performance improvements from #1944 - template synchronization through #1964, agent/contributor guide updates, dependency and pre-commit updates, and related maintenance ## v3 compatibility This backport deliberately preserves the v3 architecture: - LLVM/MLIR remains optional and continues to use LLVM/MLIR 21. - QIR support is available behind the existing MLIR-dependent feature flags. - The mandatory LLVM/MLIR 22 transition from #1953 and compiler-collection changes that depend on the v4 MLIR/QCO redesign are not included. - #1965 is adapted to retain optional MLIR and the v3 documentation roles while preserving its CMake and QDMI behavior. ## Validation - configured and built the complete non-MLIR library - configured the MLIR build against LLVM/MLIR 21.1.8 - built and ran focused DD, FoMaC, QDMI driver/registry/device, and QIR tests - verified 435 #1965-affected C++ test cases, with two expected device capability skips - configured MQT Core as an embedded CMake subproject with all bundled devices disabled by default - configured an embedded build with only the DDSIM QDMI device enabled - built and ran the device-free registry suite: 11 tests passed - focused Python FoMaC suite: 181 passed, two expected non-MLIR skips - regenerated Python stubs without a diff - complete lint, lockfile validation, commit-signature audit, and `git diff --check` passed The pre-existing v3 test configuration still requires `llc` even when MLIR is disabled. The non-MLIR library build itself succeeds; MLIR/QIR validation used LLVM/MLIR 21. ## Checklist - [x] The pull request only contains commits that are focused and relevant to this change. - [x] I have added appropriate tests that cover the new/changed functionality. - [x] I have updated the documentation to reflect these changes. - [x] I have added entries to the changelog for any noteworthy additions, changes, fixes, or removals. - [x] I have added migration instructions to the upgrade guide (if needed). - [x] The changes follow the project's style guidelines and introduce no new warnings. - [x] The changes are fully tested and pass the CI checks. - [x] I have reviewed my own code changes. **If PR contains AI-assisted content:** - [x] Any agent that created, edited, or submitted GitHub content was explicitly authorized for that scope, as required by our AI Usage Guidelines. - [x] Every agent-authored or agent-edited public text body begins with the visible disclosure `🤖 *AI text below* 🤖` (titles are exempt). - [x] I have disclosed AI assistance in the PR description. - [x] I confirm that I have personally reviewed and understood all AI-generated content, and accept full responsibility for it. --------- Signed-off-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> Signed-off-by: Lukas Burgholzer <burgholzer@me.com> Signed-off-by: Roberto Turrado Camblor <rturrado@gmail.com> Signed-off-by: rturrado <rturrado@gmail.com> Co-authored-by: mqt-app[bot] <219534693+mqt-app[bot]@users.noreply.github.com> Co-authored-by: renovate[bot] <29139614+renovate[bot]@users.noreply.github.com> Co-authored-by: Daniel Haag <121057143+denialhaag@users.noreply.github.com> Co-authored-by: simon1hofmann <119581649+simon1hofmann@users.noreply.github.com> Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: Roberto Turrado Camblor <rturrado@gmail.com> Co-authored-by: Yannick Stade <100073938+ystade@users.noreply.github.com>
