Moe Charm (CI)	7b5ee8cee2	Phase v5-3: O(1) path optimization for C6-only v5 ... - Single TLS segment (eliminates slot search loop) - O(1) page_meta_of() (direct segment range check, no iteration) - __builtin_ctz for O(1) free page finding in bitmap - Simplified free path using page_meta_of() only (no find_page) - Partial limit 1 (minimal list traversal) Performance: - Before (v5-2): 14.7M ops/s - After (v5-3): 38.5M ops/s (+162%) - vs baseline: 44.9M ops/s (-14%) - SEGV: None, stable at ws=800 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2025-12-11 04:33:16 +09:00
Moe Charm (CI)	e0fb7d550a	Phase v5-2: SmallObject v5 C6-only 本実装 (WIP - header fix) ... 本実装修正: - tiny_region_id_write_header() を追加: USER pointer を正しく返す - TLS slot からの segment 探索 (page_meta_of) - Page-level allocation で segment 再利用 - 2MiB alignment 保証 (4MiB 確保 + alignment) - free パスの route 修正 (v4 から v5 への fallthrough 削除) 動作確認: - SEGV 消失: alloc/free 基本動作 OK - 性能: ~18-20M ops/s (baseline 43-47M の約 40-45%) - 回帰原因: TLS slot 線形探索 O(n)、find_page O(n) 残タスク: - O(1) segment lookup 最適化 (hash または array 直接参照) - find_page 除去 (segment lookup 成功時) - partial_count/list 管理の最適化 ENV デフォルト OFF なので本線影響なし。 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2025-12-11 04:14:51 +09:00
