Image file obtaining method and apparatus

An image file obtaining apparatus, comprising:

• a memory storing computer-readable instructions;
• and
• a processor coupled to the memory, wherein the processor is configured to execute the computer-readable instructions in the memory to perform:
• determining a first value of each of N tasks in program source code, wherein the first value is a ratio of first duration to second duration, the first duration is duration required for executing said each of the N tasks, the second duration is duration required for loading said each of the N tasks, and N is a positive integer;
• sorting the N tasks in descending order of the first values;
• and
• linking the sorted N tasks to obtain an image file, wherein
• the processor is further configured to perform:
• obtaining a functional dependency relationship of each of the N tasks, wherein the functional dependency relationship is a call relationship between functions comprised in said each of the N tasks;
• and
• the linking comprises:
• linking, based on the functional dependency relationship of each of the N tasks, the functions comprised in each of the sorted N tasks, wherein parts of the program source code corresponding to the sorted and linked N tasks are compiled to obtain the image file.

A non-transitory computer-readable storage medium storing computer-readable instructions, wherein when the computer-readable instructions are run on a computer apparatus, the computer apparatus is enabled to perform a method comprising:

• determining a first value of each of N tasks in program source code, wherein the first value is a ratio of first duration to second duration, the first duration is duration required for executing said each of the N tasks, the second duration is duration required for loading said each of the N tasks, and N is a positive integer;
• sorting the N tasks in descending order of the first values;
• and
• linking the sorted N tasks to obtain an image file, wherein
• the method further comprises:
• obtaining a functional dependency relationship of each of the N tasks, wherein the functional dependency relationship is a call relationship between functions comprised in said each of the N tasks;
• and
• the linking comprises:
• linking, based on the functional dependency relationship of each of the N tasks, the functions comprised in each of the sorted N tasks, wherein parts of the program source code corresponding to the sorted and linked N tasks are compiled to obtain the image file.
