研究方向

First, review existing integration tests in the repository, such as those for other toolchains like MonoAOTCppToolchain. Examine the class MonoAOTLLVMToolchain in the source code to understand its methods and expected behavior. Refer to issue #2533 for context on what needs to work and fail properly. Then, create test cases that verify successful execution and failure scenarios, following the pattern of existing test files.
