I have amd64 world + GENERIC building with GCC 12 as of today on a branch and will try to get that merged soon and then switch the Jenkins job over to GCC 12. GCC 12 requires a couple of not-quite-trivial fixes. One is that the libirdma version script is broken still from when it was first imported and binutils chokes on it. It's probably a bug in lld that it doesn't reject it. The second is arguably a bug in GCC that requires a one-line change in libc++'s header. There is an upstream review for LLVM that will hopefully land soon so that I can get the green light for merging the fix into the in-tree LLVM. -- John Baldwin
