Process-Oriented GCC Failure Analysis based on Fault Injection

This paper presents a process-oriented GCC failure analysis method based on fault injection. We first analyze the process of GCC, systematically define the fault modes of GCC, and establish a GCC fault mode library. We also propose a software fault injection method based on SystemTap and develop a related fault injection tool. Subsequently, we proceed to carry out a series of fault injection experiments on GCC, aiming to unearth potential reliability issues. These experiments serve as a means to identify modules within GCC that are susceptible to failures and to propose potential enhancements. The results of these experiments unequivocally underline the existing problems in fault tolerance mechanisms across various aspects of GCC. These findings underscores the significance of our approach in failure analysis and reliability evaluation of GCC. Through a holistic analysis of diverse fault modes and their associated manifestations, our approach contributes to a more profound understanding of GCC failure behavior. It offers valuable insights to guide future optimization endeavors.
