From 4ef2261e970dbd5bb928f50b961101e545f43bae Mon Sep 17 00:00:00 2001 From: tomoaki Date: Mon, 22 Dec 2025 03:33:30 +0900 Subject: [PATCH] fix(joinir): Phase 269 P1.2 - static call normalization for this.method() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: - `this.method()` calls in static box loops were using string constant "StringUtils" as receiver - This violated Box Theory (static box this should not be runtime object) - Pattern8 was trying to pass receiver to JoinIR, causing SSA/PHI issues Solution (3-part fix): 1. **MeResolverBox Fail-Fast** (stmts.rs): Remove string fallback, error message cleanup 2. **ReceiverNormalizeBox** (calls/build.rs): Normalize `this/me.method()` → static call at compile-time 3. **Pattern8 Skip Static Box** (pattern8_scan_bool_predicate.rs): Reject Pattern8 for static box contexts Key changes: - **stmts.rs**: Update error message - remove MeBindingInitializerBox mentions - **calls/build.rs**: Add This/Me receiver check, normalize to static call if current_static_box exists - **calls/lowering.rs**: Remove NewBox-based "me" initialization (2 locations - fixes Stage1Cli regression) - **pattern8_scan_bool_predicate.rs**: Skip Pattern8 for static boxes (use Pattern1 fallback instead) Result: - ✅ phase269_p1_2_this_method_in_loop_vm.sh PASS (exit=7) - ✅ No regression: phase259_p0_is_integer_vm PASS - ✅ No regression: phase269_p0_pattern8_frag_vm PASS - ✅ Stage1Cli unit tests PASS - ✅ MIR uses CallTarget::Global, no const "StringUtils" as receiver 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 --- ...phase269_p1_2_this_method_in_loop_min.hako | 46 ++++++++++++++ src/mir/builder/calls/build.rs | 18 +++++- src/mir/builder/calls/lowering.rs | 2 + .../patterns/pattern8_scan_bool_predicate.rs | 22 ++++++- src/mir/builder/stmts.rs | 62 ++++++++++++++----- .../phase269_p1_2_this_method_in_loop_vm.sh | 27 ++++++++ 6 files changed, 157 insertions(+), 20 deletions(-) create mode 100644 apps/tests/phase269_p1_2_this_method_in_loop_min.hako create mode 100644 tools/smokes/v2/profiles/integration/apps/phase269_p1_2_this_method_in_loop_vm.sh diff --git a/apps/tests/phase269_p1_2_this_method_in_loop_min.hako b/apps/tests/phase269_p1_2_this_method_in_loop_min.hako new file mode 100644 index 00000000..6c45e91f --- /dev/null +++ b/apps/tests/phase269_p1_2_this_method_in_loop_min.hako @@ -0,0 +1,46 @@ +static box StringUtils { + equals(other) { + return true + } + + is_digit(ch) { + // 元の実装を再現（or チェーン） + return ch == "0" or ch == "1" or ch == "2" + } + + is_integer(s) { + // 元の実装に近づける + if s.length() == 0 { + return false + } + + local start = 0 + if s.substring(0, 1) == "-" { + if s.length() == 1 { + return false + } + start = 1 + } + + local i = start + loop(i < s.length()) { + // 🔥 THIS IS THE BUG: this.is_digit() in loop + if not this.is_digit(s.substring(i, i + 1)) { + return false + } + i = i + 1 + } + return true + } + + toString() { + return "StringUtils()" + } +} + +static box Main { + main() { + // 元のテストケースと同じ + return StringUtils.is_integer("123") ? 7 : 1 + } +} diff --git a/src/mir/builder/calls/build.rs b/src/mir/builder/calls/build.rs index b379e064..4fa12d72 100644 --- a/src/mir/builder/calls/build.rs +++ b/src/mir/builder/calls/build.rs @@ -136,8 +136,22 @@ impl MirBuilder { return res; } - // 3.
