**Problem**: Multiple infinite loops in parser expression handling
- ParserIdentScanBox.scan_ident: bb985
- ParserExprBox.parse_factor2: bb1662 (2 loops)
- ParserExprBox.parse_term2: bb1704
- ParserExprBox.parse_sum2
- ParserExprBox.parse_expr2
- ParserExprBox.parse_args2
**Root Cause**: Same `loop(cont == 1)` + nested if-else pattern as Part 1
- MirBuilder generates PHI self-references
- Loop exits jump to wrong blocks
**Solution**: MirBuilder-friendly explicit continue/break pattern
```hako
// BAD:
loop(cont == 1) {
if condition { action } else { cont = 0 }
}
// GOOD:
loop(true) {
if condition { action; continue }
break
}
```
**Files Modified**:
- lang/src/compiler/parser/scan/parser_ident_scan_box.hako: scan_ident explicit continue
- lang/src/compiler/parser/expr/parser_expr_box.hako: 6 loops fixed
- parse_factor2: 2 method chaining loops (new/identifier)
- parse_term2: */ operators
- parse_sum2: +- operators
- parse_expr2: &&|| operators
- parse_args2: argument list parsing
**Progress**: 9 total loop patterns fixed (Part 1: 3, Part 2: 6)
**Remaining**: parse_program2 still has infinite loop at different location (bb2816 vs original bb2854) - investigating in Part 3

Hakorune Lang Line — Rust-less Kernel (C ABI)
Scope
- This
lang/tree hosts the script-driven C ABI kernel artifacts for Phase 20.9+. - Goal: keep the runtime data plane callable without Rust on the hot path (Hakorune → LLVM → C ABI).
Principles
- Separation: do not mix Rust crates or cargo-specific layout under this tree.
- Ownership & ABI:
- Any
char*returned across the ABI is owned by the callee and must be freed viahako_mem_free(). - Do not mix CRT
free()across boundaries.
- Any
- Fail‑Fast: no silent fallbacks. Missing symbols must be observable via short diagnostics.
Layout (initial)
c-abi/— C shim(s) and headers for the minimal kernel surfaceREADME.md— responsibilities, build notes, platform caveatsinclude/— public headers (mirrored or thin wrappers)shims/— libc-backed shim(s) for canaries and local testing
Build & Link (dev)
- C shim: build a shared library to satisfy symbols for the LLVM line canaries.
- Link flags example:
- Linux:
-L$(pwd)/target/release -Wl,-rpath,$(pwd)/target/release -lhako_kernel_shim
- Linux:
Non‑Goals
- Plugin loader, HostBridge router, Box/Type system — kept in Rust.
Selfhost Launcher (AOT)
Dev line (Stage1 core – experimental)
- Dev build:
tools/selfhost/build_stage1.sh→ producestarget/selfhost/hakorune - Role:
- Fast iteration用の Stage1 selfhost バイナリ（Ny Executor / CLI 実験など）。
- new CLI/runner 機能はまずこちらで開発・検証する。
Stable line (lang bin – snapshot)
- Stable binary:
lang/bin/hakorune - Build (pure-lang launcher, legacy bring-up):
lang/build/build_runner.sh→ produceslang/bin/hakorune- Requirements: LLVM 18 dev (
llvm-config-18)
- Policy（Phase 25.1 以降の想定）:
target/selfhost/hakoruneで十分に安定したら、その成果物をlang/bin/hakoruneに昇格させる（手動コピー or 専用スクリプト）。lang/bin/hakoruneは「last known good」の Stage1 コア EXE として扱い、配布や外部からの参照時は原則こちらを基準にする。
Notes
lang/以下は「最終的に 1 つの Stage1 コア EXE（hakorune）を構成するソース群」という前提で整理する。target/selfhost/hakoruneは開発中の最新版、lang/bin/hakoruneは安定版スナップショットという役割分担にする。
