Hi Here's a list of the items that, time permitting, I'd like to get into 3.21. Plus any recently-released FreeBSD 13.2 fixes. inconsistent RDTSCP support on x86_64 https://bugs.kde.org/show_bug.cgi?id=374596 I was recently contacted by the patch author for this one. It's a bit tricky to test as it requires ancient hardware or some sort of virtualization. That or a good knowledge of all possible hwcaps combinations. Likely false positive "uninitialised value(s)" for __wmemchr_avx2 and __wmemcmp_avx2_movbe https://bugs.kde.org/show_bug.cgi?id=397083 Looks fairly straightforward, I just need to find a machine less old than mine to test it on. Enhancement: add a client request to DHAT to mark memory to be histogrammed https://bugs.kde.org/show_bug.cgi?id=464103 Again fairly simple and straightforward. Add mismatched detection to C++ 17 aligned new/delete https://bugs.kde.org/show_bug.cgi?id=433859 Add validation to C++17 aligned new/delete alignment size https://bugs.kde.org/show_bug.cgi?id=433857 Add mismatched detection to C++ 14 sized delete https://bugs.kde.org/show_bug.cgi?id=467441 aligned_alloc problems, part 2 https://bugs.kde.org/show_bug.cgi?id=466105 There's a lot of stuff there (patch in the first bugzi item). All the C++ stuff is nice to have (and mostly also covered by ASan) but I don't think that that kind of error happens frequently in the wild. memalign and aligned alloc are more likely to be useful for detecting implementation defined behaviour.
