The intern_stack function is responsible for retrieving or creating a stack_id based on the provided frame_id and prefix_id. It first generates a key using the frame_id and prefix_id values. If the stack corresponding to the key is found in the stackMap, it is returned. Otherwise, a new stack is created by appending the prefix_id and frame_id to the stackTable. The key and the index of the newly created stack are added to the stackMap for future reference. The _intern_frame function is responsible for retrieving or creating a frame_id based on the provided frame string. If the frame_id corresponding to the frameString is found in the frameMap, it is returned. Otherwise, a new frame is created by appending relevant information to the frameTable and adding the frameString to the string_id through _intern_string. The _intern_string function will gets a matching string, or saves the new string and returns a String ID.
