nyash-codex	99d329096f	feat(joinir): Phase 176 Pattern2 multi-carrier lowering complete ... Task 176-1: Pattern2 limitation investigation - Identified 10 limitation points where only position carrier was handled - Added TODO markers for Phase 176-2/3 implementation - Created phase176-pattern2-limitations.md documentation Task 176-2: CarrierUpdateLowerer helper implementation - Implemented emit_carrier_update() helper function - Supports CounterLike and AccumulationLike UpdateExpr patterns - Added 6 unit tests (all passing) - Fail-Fast error handling for carrier/variable not found Task 176-3: Pattern2 lowerer multi-carrier extension - Extended header PHI generation for all carriers - Implemented loop update for all carriers using emit_carrier_update() - Extended ExitLine/ExitMeta construction for all carriers - Updated function call/jump args to include all carriers - 9/10 tests passing (1 pre-existing test issue) Task 176-4: E2E testing and bug fixes - Fixed Trim pattern loop_var_name overwrite bug (pattern2_with_break.rs) - Fixed InstructionRewriter latch_incoming mapping bug - All E2E tests passing (RC=0): pos + result dual-carrier loops work - test_jsonparser_parse_string_min2.hako verified Task 176-5: Documentation updates - Created phase176-completion-report.md - Updated phase175-multicarrier-design.md with completion status - Updated joinir-architecture-overview.md roadmap - Updated CURRENT_TASK.md with Phase 176 completion + Phase 177 TODO - Updated loop_pattern_space.md F-axis (multi-carrier support complete) Technical achievements: - Pattern2 now handles single/multiple carriers uniformly - CarrierInfo architecture proven to work end-to-end - Two critical bugs fixed (loop_var overwrite, latch_incoming mapping) - No regressions in existing tests Next: Phase 177 - Apply to JsonParser _parse_string full implementation	2025-12-08 15:17:53 +09:00
nyash-codex	24aa8ced75	feat(joinir): Phase 175 - P5 multi-carrier architecture validation ... Task 175-1: Analyzed _parse_string carrier candidates - Identified 3 carriers: pos (position), result (buffer), is_ch_match (promoted) - Categorized as: required carriers (pos, result), promoted carrier (is_ch_match) Task 175-2: Validated existing boxes support multi-carrier - CarrierInfo: Vec<CarrierData> supports arbitrary carriers ✅ - LoopUpdateAnalyzer: Loops over all carriers ✅ - ExitMeta: Vec<(String, ValueId)> supports all exit bindings ✅ - ExitLineReconnector: Reconnects all carriers to variable_map ✅ - No code changes needed - architecture already supports it! Task 175-3: PoC test revealed Pattern2 limitation - Test: test_jsonparser_parse_string_min2.hako (pos + result carriers) - CarrierInfo detected 3 carriers correctly (pos, result, is_ch_match) - variable_map contains all carriers at pattern2_start - BUT: Pattern2's Trim optimization only emits pos carrier in MIR - MIR shows result stays as empty string (no loop update emitted) - Root cause: Trim pattern focuses on position-only optimization Task 175-4: Documentation updates - Created: phase175-multicarrier-design.md (comprehensive analysis) - Updated: CURRENT_TASK.md (Phase 175 completion) - Updated: routing.rs (added JsonParserStringTest2 whitelist) Key Finding: - Architecture is sound ✅ - all boxes support multi-carrier - Pattern2 implementation gap ❌ - Trim optimization ignores non-position carriers - Phase 176 scope: Extend Pattern2 to emit all carrier updates Next: Phase 176 for escape sequence handling and full multi-carrier emission	2025-12-08 13:34:43 +09:00
