Item 109 from the old PROBLEMS file (no test case available):
----------------------------------------
It is desirable to avoid converting INDEX to SImode if a narrower

Great to see that you pay enough attention to stop the reporter from closing his own PRs. I wish you would be just as fast with actually doing something about them. It is not even clear whether these problems still exist! If this still not OK with you, I suggest you do something about these 15+ years old problems, or close these and re-file under your own account. They may not bother you but I don't want them anymore in my list. ^ permalink raw reply [flat|nested] 9+ messages in thread
