nyash-codex	255517ed58	fix(cse): Include callee in Call instruction key generation ... Previously, CSE's instruction_key() ignored the callee field, which could cause different method calls on the same receiver to be incorrectly merged: %r1 = call Method { receiver: %obj, method: "upper" } () %r2 = call Method { receiver: %obj, method: "lower" } () // Both had key "call_<obj>_" - WRONG! Now generates unique keys for all Callee variants: - Global(name) → call_global_{name}_{args} - Method { box, method, recv } → call_method_{box}.{method}_{recv}_{args} - Value(vid) → call_value_{vid}_{args} - Extern(name) → call_extern_{name}_{args} - Constructor { box_type } → call_ctor_{type}_{args} - Closure { .. } → call_closure_{func}_{args} - None (legacy) → call_legacy_{func}_{args} 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-12-05 23:33:06 +09:00
nyash-codex	120fbdb523	fix(mir): Receiver used_values for DCE + trace + cleanup ... - Fix: Call with Callee::Method now includes receiver in used_values() - Prevents DCE from eliminating Copy instructions that define receivers - Pattern 3 (loop_if_phi.hako) now works correctly (sum=9) - Add: NYASH_DCE_TRACE=1 for debugging eliminated instructions - Shows which pure instructions DCE removes and from which block - Cleanup: Consolidate Call used_values to single source of truth - Early return in methods.rs handles all Call variants - Removed duplicate match arm (now unreachable!()) - ChatGPT's suggestion for cleaner architecture - Docs: Phase 166 analysis of inst_meta layer architecture - Identified CSE pass callee bug (to be fixed next) - Improvement proposals for CallLikeInst 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-12-05 23:26:55 +09:00
