--- Comment #22 from Julian Seward <jsew...@acm.org> --- (In reply to Eyal from comment #21) > Will anyone consider the patch? This (problem) is definitely something I want to deal with, and your patch seems like a good starting place. However, 3.17 is imminent and I would prefer to defer till after 3.17 is done. In part because I'd like to do more general qualifying runs against gcc-11 and clang-11 compiled code. The patch might need to be generalised, so as to make it handle different vector widths, lane widths and even maybe the scalar cases. Regarding the frequency of false positives, this is the first time I have heard of this problem. By comparison, we have many bug reports that relate to (eg) clang/gcc doing equality comparisons on partially defined data. I'd accept also though, that if this is a new optimisation in clang, then we might get more such reports in the future. But right now it doesn't seem critical enough to put into 3.17. -- You are receiving this mail because: You are watching all bug changes.
