From 8b44c5009f118fa4a5e0a0f98c65b7f37a4dd1e9 Mon Sep 17 00:00:00 2001 From: nyash-codex Date: Thu, 13 Nov 2025 20:16:20 +0900 Subject: [PATCH] fix(mir): fix else block scope bug - PHI materialization order MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root Cause: - Else blocks were not propagating variable assignments to outer scope - Bug 1 (if_form.rs): PHI materialization happened before variable_map reset, causing PHI nodes to be lost - Bug 2 (phi.rs): Variable merge didn't check if else branch modified variables Changes: - src/mir/builder/if_form.rs:93-127 - Reordered: reset variable_map BEFORE materializing PHI nodes - Now matches then-branch pattern (reset → materialize → execute) - Applied to both "else" and "no else" branches for consistency - src/mir/builder/phi.rs:137-154 - Added else_modified_var check to detect variable modifications - Use modified value from else_var_map_end_opt when available - Fall back to pre-if value only when truly not modified Test Results: ✅ Simple block: { x=42 } → 42 ✅ If block: if 1 { x=42 } → 42 ✅ Else block: if 0 { x=99 } else { x=42 } → 42 (FIXED!) ✅ Stage-B body extraction: "return 42" correctly extracted (was null) Impact: - Else block variable assignments now work correctly - Stage-B compiler body extraction restored - Selfhost builder path can now function - Foundation for Phase 21.x progress 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- docs/ENV_VARS.md | 13 ++-- .../development/strategies/de-rust-roadmap.md | 28 ++++++++ docs/reference/invariants.md | 3 +- docs/reference/language/README.md | 3 + .../reference/language/variables-and-scope.md | 66 +++++++++++++++++++ lang/src/llvm_ir/boxes/aot_prep.hako | 27 +------- .../boxes/aot_prep/helpers/common.hako | 15 +++-- .../boxes/aot_prep/passes/binop_cse.hako | 30 +-------- .../aot_prep/passes/collections_hot.hako | 63 ++++++++++-------- .../boxes/aot_prep/passes/const_dedup.hako | 30 +-------- .../boxes/aot_prep/passes/loop_hoist.hako | 26 +------- .../llvm_ir/boxes/aot_prep/passes/strlen.hako | 27 +------- nyash.toml | 8 +++ src/mir/builder/if_form.rs | 35 ++++++---- src/mir/builder/phi.rs | 9 ++- tools/hakorune_emit_mir.sh | 2 + tools/perf/microbench.sh | 54 +++++++++++---- .../emit_provider_no_jsonfrag_canary.sh | 37 +++++++++++ .../phase215/stageb_scope_extract_canary.sh | 38 ++++++----- 19 files changed, 309 insertions(+), 205 deletions(-) create mode 100644 docs/reference/language/variables-and-scope.md create mode 100644 tools/smokes/v2/profiles/quick/core/phase215/emit_provider_no_jsonfrag_canary.sh diff --git a/docs/ENV_VARS.md b/docs/ENV_VARS.md index 23cd2cb4..f8f97d5a 100644 --- a/docs/ENV_VARS.md +++ b/docs/ENV_VARS.md @@ -37,6 +37,9 @@ Parser/Stage‑B - HAKO_STAGEB_FUNC_SCAN=1 - Dev‑only: inject a `defs` array into Program(JSON) with scanned method definitions for `box Main`. +- HAKO_STAGEB_BODY_EXTRACT=0|1 + - Toggle Stage‑B body extractor.
