From 35f2836d912a6049d78b94a13de0915b581ce049 Mon Sep 17 00:00:00 2001 From: ASDAlexander77 Date: Fri, 17 Jul 2026 01:02:51 +0100 Subject: [PATCH 1/4] Fix in-operator crash and literal-string field lookup; add regression tests - mlirGenInLogic assumed any `in` expression whose right side has `.length` was a numeric-index check, so a string-literal left side (e.g. "length" in arr) got cast to an index type and crashed LLVM translation. Now falls through to the general field-lookup path for string literals. - getFieldTypeByFieldName didn't strip LiteralType wrappers, so `in` checks against const strings/string literals (e.g. "length" in "hi") incorrectly resolved to false instead of using the underlying type's field lookup. - Add 00in_method_names.ts and 00class_structural_extends.ts covering the #238 area (in-operator and structural extends against classes), wired into both test-compile and test-jit CMake targets. Verified against the full 696-test suite, no regressions. - Document a separate, deferred bug in docs/bugs/: generators lose their state across manual .next() calls (only for...of works). Root-caused to const bindings lacking backing storage; a first fix attempt broke unrelated interface/symbol tests and was reverted, so the fix itself is left for a dedicated follow-up. --- docs/bugs/00generator_manual_next.ts | 48 ++++++++++++++++++ .../TypeScript/MLIRLogic/MLIRTypeHelper.h | 2 + tslang/lib/TypeScript/MLIRGenImpl.h | 10 +++- tslang/test/tester/CMakeLists.txt | 4 ++ .../tests/00class_structural_extends.ts | 29 +++++++++++ tslang/test/tester/tests/00in_method_names.ts | 49 +++++++++++++++++++ 6 files changed, 141 insertions(+), 1 deletion(-) create mode 100644 docs/bugs/00generator_manual_next.ts create mode 100644 tslang/test/tester/tests/00class_structural_extends.ts create mode 100644 tslang/test/tester/tests/00in_method_names.ts diff --git a/docs/bugs/00generator_manual_next.ts b/docs/bugs/00generator_manual_next.ts new file mode 100644 index 000000000..69ead4ea6 --- /dev/null +++ b/docs/bugs/00generator_manual_next.ts @@ -0,0 +1,48 @@ +// regression test: calling .next() manually on a real `function*` generator (as opposed +// to driving it via `for...of`) used to never advance the generator's internal state. +// +// root cause: a `const` binding was stored in the symbol table as a bare SSA value with +// no backing stack storage.

That broke as soon as a callback itself called the helper again (needed for AnyCompareOp's new multi-way coercion dispatch), producing an "operation with block successors must terminate its parent block" verifier error. It now re-reads the actual insertion block after each builder runs, so it composes safely when nested. AnyCompareOpLowering's local workaround (nestableConditional) is removed in favor of the shared, now-fixed helper. 01tuple.ts's `assert(obj8.field1 === 10)` relied on the old, buggy === semantics that coerced like == (fixed in the previous commit) -- field1 is string-typed and holds the coerced "10", so strict equality against the number 10 is correctly false. Updated to match the coercion pattern already used elsewhere in the same file. Full suite: 700/700 passing.
