This is the best question for me. Writing these codes in C language is the best way to learn the file structure of jvm/dalvik/pe. This process makes me like C language more. For me, I think it is simple and pure, which is enough.
In multi-threaded mode, each thread will create a separate memory pool. If in single-threaded mode, a global memory pool is used. You can refer to https://github.com/neocanable/garlic/blob/72357ddbcffdb75641.... The x_alloc and x_alloc_in in it indicate where the memory is allocated. When each task ends, the memory allocated in the memory pool is released, and the cycle repeats.
