refactor(phase27.13): Introduce ValueId range management system
Introduce centralized ValueId range allocation to prevent ID conflicts between lowering modules. Changes: 1. New file: src/mir/join_ir/lowering/value_id_ranges.rs - Base address constants for each lowering module - Helper functions: entry(offset), loop_step(offset) - Range validation test: test_value_id_ranges_no_overlap 2. Range allocation (resolved conflict): - min_loop: 1000-2999 (entry: 1000+, loop: 2000+) - skip_ws: 3000-4999 (entry: 3000+, loop: 4000+) - funcscanner_trim: 5000-6999 (entry: 5000+, loop: 6000+) - stage1_using_resolver: 7000-8999 (entry: 7000+, loop: 8000+) ← CHANGED 3. Updated stage1_using_resolver.rs to use value_id_ranges helpers - ValueId(5000) → vid::entry(0) // 7000 - ValueId(6000) → vid::loop_step(0) // 8000 4. Updated lowering/mod.rs to include value_id_ranges module Results: - ✅ Build success (warnings only, no errors) - ✅ Tests: 2/2 existing tests pass (type_sanity, empty_module_returns_none) - ✅ value_id_ranges test pass (range overlap validation) - ✅ ValueId conflict resolved (trim vs stage1_using_resolver) Benefits: - Centralized range management prevents conflicts - Type-safe: const fn for compile-time calculation - Self-documenting: comments clarify ranges - Easy extension: future lowerings can use 9000+, 11000+, etc.

//! ValueId Range Allocation for JoinIR Lowering Modules
|
||||
//!
|
||||
//! This module manages ValueId ranges for each JoinIR lowering module to prevent
|
||||
//! ID conflicts when multiple lowerings coexist.
|
||||
//!
|
||||
//! ## Current Allocations
|
||||
//!
|
||||
//! | Module | Range | Entry | Loop | Notes |
|
||||
//! |-----------------------|-----------|-------|-------|-------|
|
||||
//! | min_loop | 1000-2999 | 1000+ | 2000+ | Minimal loop test |
|
||||
//! | skip_ws | 3000-4999 | 3000+ | 4000+ | Skip whitespace |
|
||||
//! | funcscanner_trim | 5000-6999 | 5000+ | 6000+ | Trim whitespace |
|
||||
//! | stage1_using_resolver | 7000-8999 | 7000+ | 8000+ | Stage-1 using resolver |
|
||||
//!
|
||||
//! ## Usage Example
|
||||
//!
|
||||
//! ```rust,ignore
|
||||
//! use crate::mir::join_ir::lowering::value_id_ranges::stage1_using_resolver as vid;
|
||||
//!
|
||||
//! let entries_param = vid::entry(0); // ValueId(7000)
|
||||
//! let n_param = vid::entry(1); // ValueId(7001)
|
||||
//! let entries_loop = vid::loop_step(0); // ValueId(8000)
|
||||
//! let n_loop = vid::loop_step(1); // ValueId(8001)
|
||||
//! ```
|
||||
//!
|
||||
//! ## Future Extensions
|
||||
//!
|
||||
//! When adding new lowering modules, allocate ranges in increments of 2000:
|
||||
//! - 9000-10999 (next available)
|
||||
//! - 11000-12999

//! - 13000-14999
