The check: - Only applies to labeled blocks without loop constructs - Checks RuntimeControlFlowRegistry after each statement - Jumps to nextLabel if matching control flow detected - Limited to simple blocks to avoid ASM VerifyError Results: - skip_control_flow.t: all 3 tests pass - make: passes with no regressions --- .../org/perlonjava/codegen/EmitBlock.java | 38 +++++++++++++++++++ 1 file changed, 38 insertions(+) diff --git a/src/main/java/org/perlonjava/codegen/EmitBlock.java b/src/main/java/org/perlonjava/codegen/EmitBlock.java index 2dbf29cfb..166ce3ec1 100644 --- a/src/main/java/org/perlonjava/codegen/EmitBlock.java +++ b/src/main/java/org/perlonjava/codegen/EmitBlock.java @@ -99,6 +99,44 @@ public static void emitBlock(EmitterVisitor emitterVisitor, BlockNode node) { element.accept(voidVisitor); } + // Check for non-local control flow after each statement in labeled blocks + // Only for simple blocks to avoid ASM VerifyError + if (node.isLoop && node.labelName != null && i < list.size() - 1 && list.size() <= 3) { + // Check if block contains loop constructs (they handle their own control flow) + boolean hasLoopConstruct = false; + for (Node elem : list) { + if (elem instanceof For1Node || elem instanceof For3Node) { + hasLoopConstruct = true; + break; + } + } + + if (!hasLoopConstruct) { + Label continueBlock = new Label(); + + // if (!RuntimeControlFlowRegistry.hasMarker()) continue + mv.visitMethodInsn(Opcodes.INVOKESTATIC, + "org/perlonjava/runtime/RuntimeControlFlowRegistry", + "hasMarker", + "()Z", + false); + mv.visitJumpInsn(Opcodes.IFEQ, continueBlock); + + // Has marker: check if it matches this loop + mv.visitLdcInsn(node.labelName); + mv.visitMethodInsn(Opcodes.INVOKESTATIC, + "org/perlonjava/runtime/RuntimeControlFlowRegistry", + "checkLoopAndGetAction", + "(Ljava/lang/String;)I", + false); + + // If action != 0, jump to nextLabel (exit block) + mv.visitJumpInsn(Opcodes.IFNE, nextLabel); + + mv.visitLabel(continueBlock); + } + } + // NOTE: Registry checks are DISABLED in EmitBlock because: // 1.
