PR-2.5 — Prepare Call Frame Structure for Closures and Coroutines

Briefing

Before introducing closures and coroutines, the call frame structure must be neutral and future-proof, without HIP-specific fields.

Target

  • Simplify the call frame to a minimal, generic structure.
  • Remove any HIP/borrow/gate-related fields.

Work items

  • Review the call frame struct.

  • Remove fields tied to scope frames, borrow state, or gates.

  • Ensure the frame contains only:

    • Function identifier.
    • Program counter.
    • Base stack pointer.
    • Locals or register area (if applicable).
  • Keep the structure simple and extensible.

Acceptance checklist

  • Call frame struct has no HIP-related fields.
  • VM call/return paths compile and work.
  • cargo test passes.

Tests

  • Existing call-related tests must still pass.

Junie instructions

You MAY:

  • Remove unused fields from the frame.
  • Refactor call/return code to match the new structure.

You MUST NOT:

  • Introduce closure or coroutine logic yet.
  • Redesign the call stack architecture.

If unclear:

  • Ask before changing frame responsibilities.

PR-2.6 — Remove Dead Runtime Modules and Symbols

Briefing

After the VM reset, there will be leftover modules, helpers, or symbols that are no longer referenced. This PR performs a final cleanup pass.

Target

  • Remove dead or unreachable runtime code.
  • Ensure the VM crate has a minimal, clean surface.

Work items

  • Use compiler warnings and search tools to find:

    • Unused modules.
    • Unused structs/enums/functions.
    • Legacy HIP/RC terminology.
  • Remove dead code.

  • Update module trees and public exports.

Acceptance checklist

  • No dead modules remain.
  • No HIP/RC terminology found in the VM crate.
  • cargo test passes.

Tests

  • Existing tests only.

Junie instructions

You MAY:

  • Remove unused code and modules.
  • Update mod.rs and exports.

You MUST NOT:

  • Remove code that is still referenced.
  • Replace deleted modules with new experimental ones.

If unclear:

  • Ask before deleting anything that looks structurally important.
