rose manual sync (full REX scope)

rose upstream github repo: https://github.com/rose-compiler/rose

Support target (REX)

  • Platform: Linux only (Windows/mac/other OS dropped).
  • Languages/features: C/C++, Fortran, OpenMP, OpenACC, OpenCL, CUDA.
  • Frontend: Clang/LLVM for C/C++ (LLVM 20); Fortran via OFP with experimental Flang frontend in scope (imported; keep synced).
  • Hard dropped: PHP, JavaScript, Python, Ada, Jovial, EDG, Java (source language), UPC, YAML/mini-yaml, binary analysis, Sawyer, CodeThorn, and other legacy frontends/tools (excluding experimental Flang).
  • Java is still required only as a runtime dependency for the OFP Fortran parser; no Java frontend support.
  • Rosebud: keep the generator engine if present, but drop Rosebud inputs tied to dropped subsystems (e.g., binary analysis, Jovial).
  • Legacy array test suites are dropped from CompileTests and CompilerOptionsTests inventories.

Non-negotiable rules

  • Top rule: do not pause for any reason until the PR is created.
  • Manual per-commit review only. No scripts, no batch triage, no bulk patch application.
  • Commit log must only reference upstream rose/weekly history; never use local REX history for log entries (always run git log rose/weekly ... when enumerating commits).
  • Before logging any commit, verify the SHA exists in rose/weekly (e.g., git merge-base --is-ancestor <sha> rose/weekly); if not, do not log it.
  • If a commit is marked pick, apply the code change immediately (before moving on).
  • If a pick is already present in REX, record that in the Notes column and leave the REX commit column blank.
  • Decision order is strict: verify upstream SHA -> decide pick/drop -> apply (if pick) -> update commit log immediately.
  • Keep list below is authoritative; only those paths are eligible for sync.
  • Drop list below is authoritative; never reintroduce dropped paths or platforms.
  • Autotools/Tup are inventory only: do not port into CMake.
  • Preserve REX pruning decisions; do not reintroduce Boost-only subsystems or removed frontends.
  • Preserve REX modernizations that removed deprecated C++ template patterns; do not reintroduce those warning-prone constructs.
  • Flang parse-tree snapshots are upstream-generated and may contain host-specific #line markers (e.g., apple-darwin); keep them unchanged since they are not platform-support code.

Drop list (upstream-only paths not in REX)

Any upstream directory not present in the keep list is dropped by default. The explicit list below names known upstream-only subtrees. Note: tests/nonsmoke/functional/RunTests, tests/nonsmoke/functional/testSupport, tests/nonsmoke/functional/roseTests/ROSETTA, and tests/nonsmoke/functional/roseTests/astInterfaceTests/unitTests are kept (see inventory).

Manual sync workflow (no batch processing)

1) Start from origin/main with a clean working tree, then git fetch rose to ensure the upstream range is local. 2) Verify keep/drop lists (and supported languages/platforms) before touching code. Update this doc first if anything changed. 3) For each top-level directory in the inventory: - Collect the upstream commits that touch the directory (2019-01-01 → 2023-10-26). - Walk the commits in chronological order. For each commit: - Inspect with git show <commit>. - Decide pick/drop/pending based on keep/drop lists and REX rules. - If a file contains mixed hunks, apply only the relevant hunks manually (no batch application). - Record the decision immediately in the commit log below. - Mark the directory status as synced only after all its commits are handled. 4) While applying changes: - Never reintroduce dropped subsystems or platforms (EDG, Sawyer, Windows/mac, etc.). - Preserve REX C++ modernization work (no deprecated template reintroductions). - Treat Autotools/Tup edits as inventory only (record in notes, do not port). 5) After each logical chunk (e.g., a directory or feature area), build and spot-check the affected tests if applicable. 6) When the full sync is complete, run the required validations: 

cmake --build build -j32
ctest --test-dir build --output-on-failure -R astInterface
ctest --test-dir build --output-on-failure -R rex
7) Commit the changes with a message referencing the upstream commit(s), update the REX commit column in the log, and proceed to PR.
