Project Status

Canonical source: docs/status/project-status.md — this file is a tracked mirror.

Executive Summary

V1.0 release candidate ready. Self-hosting compiler, deterministic output, ARC memory management complete. 31/31 tests pass. P0/P1 bugs: zero.

Current Baseline

Metric Value
Core tests 17/17 PASS
ARC tests 14/14 PASS
Total tests 31/31 PASS
IRLower lines 2704
S2 binary size 262,112 bytes
Self-hosting S2→S3 ✅ byte-identical
Deterministic ✅ YES
P0/P1 bugs 0

ARC Status — COMPLETE

All 6 phases merged. Inline retain/release. Scope exit, return, break/continue, recursive teardown, inheritance chain. 14 ARC tests pass. Deterministic with ARC active.

V1.1 Roadmap — "Memory Performance"

⚠️ 2026-05-31: Re-prioritized based on benchmark data. See: docs/performance-report.md → docs/audit/v1.1-performance-roadmap-audit.md

Priority Task Type Impact
P0 Bump Allocator Runtime ARC workload 87× → ~5×
P0 Freelist / Allocation Pooling Runtime RSS 389MB → <50MB
P0 StringBuilder Runtime + SSO Runtime String ops 12× → ~2.5×
P1 mmap Batch / Arena Allocator Runtime Allocation granularity
P2 __this ownership metadata refactor ARC Technical debt
P2 RETURN INDEX/DEREF retain ARC ARC coverage
P2 Env.args() + Env.exePath() Feature Startup ABI

V1.2 Roadmap — "Compiler Optimizations"

Constant folding, DCE, loop unrolling, CSE, strength reduction, peephole optimizer, function inlining, register allocation tuning.

V1.3 Roadmap — "Language Features"

Inheritance, generics, interfaces, enums, pattern matching, lambdas/closures.

V2.0+ Roadmap — "Advanced"

Advanced optimizer (GVN, LICM, SROA, auto-vectorization), operator overloading, exception lowering, cycle collector, JIT/ARM64 backend.

Performance

→ Comprehensive Benchmark Report — 8 tests, 4 languages (C, C++, Go, Arimo). → Performance Summary — concise V1 performance profile. → Roadmap Audit — benchmark-based reprioritization.
