--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Haoxin Tu from comment #6) > My team nowadays are focusing on improving the quality of mature compilers. > We just developed a tool to test them and then found those bugs. Our method > might not perfect now and it only found some issues in FE, and we are > designing a more effective approach to focus on the ME or BE parts (those > parts might more important for GCC), it still needs some time for us. So I > totally agree with that you said, and maybe later reports will be more > useful for you. OK, thanks for the background information.
