<pre>
    The problem is this, I am doing a jsvm project, and I want to use 
```sh
lldb -- jsvm XXX
```
for debugging, and then I use it through the **__jit_debug_register_code** interface, but although it can break, but can not display the source code, Whether lldb does not load debug information in __jit_debug_register_code?


```cpp
void register_jit_function_aot_test(std::vector<std::tuple<std::string, uintptr_t, size_t>> func_symbols, ElfDebugInfo elf_debug_info) {
    Buffer elf_file = generate_elf_symbol_aot_test(func_symbols, elf_debug_info);

    struct jit_code_entry* entry = (struct jit_code_entry*)malloc(sizeof(struct jit_code_entry));
    entry->symfile_addr = (const char*)elf_file.bytes;
    entry->symfile_size = elf_file.num_bytes;
    entry->next_entry = __jit_debug_descriptor.first_entry;
    entry->prev_entry = NULL;
    
    if (entry->next_entry != NULL) {
        entry->next_entry->prev_entry = entry;
    }

    __jit_debug_descriptor.first_entry = entry;
    __jit_debug_descriptor.relevant_entry = entry;
    __jit_debug_descriptor.action_flag = JIT_REGISTER_FN;

    __jit_debug_register_code();  // 通知 debugger
}
```

The same thing I use with gdb is normal.
