Context를 packed struct(u32) → packed struct(u8)로 축소. ECMAScript 문법 파라미터 8개만 Context에 유지: allow_in, in_generator, in_async, in_function, is_top_level, in_decorator, in_ambient, disallow_conditional_types 나머지 11개 플래그를 Parser struct 개별 필드로 이동: is_strict_mode, in_loop, in_switch, has_simple_params, for_loop_init, in_class, in_class_field, in_static_block, has_super_class, allow_super_call, allow_super_property SavedState struct 추가: 함수 진입 시 Context + Parser 필드를 함께 save/restore. enterFunctionContext/restoreFunctionContext 패턴. Test262 98.0% (470건 실패) — regression 없음. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- SavedState에 for_loop_init 추가 + 함수 경계에서 리셋 (중첩 함수가 외부 for_loop_init을 상속하는 버그 방지) - enterFunctionContext에서 has_simple_params를 true로 리셋 (다른 필드와 일관성 유지, 기본값 보장) - 미사용 in_static_block 필드 제거 - parseSwitchStatement에서 restoreContext 헬퍼 사용으로 일관성 확보 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
