Abstract: This application discloses a code inspection method, including: obtaining first source code and test code, where the first source code includes a blocking mark, the first source code corresponds to a plurality of threads, the plurality of threads have at least one shared memory; generating, based on the first source code and the condition indicated by the test code, a plurality of execution flows under the weak memory ordering architecture for the plurality of threads that operate a same shared memory, where a busy-wait loop exists in a target execution flow that includes the blocking mark and that is in the plurality of execution flows; and determining the busy-wait loop in the target execution flow as an infinite loop if a read operation executed by a target thread in one iteration of the busy-wait loop cannot reference an unreferenced write operation.
