For example I see that commit 45ff34638f0 added the sub-directory `avx512_1`. I tried to make sense of the (outdated?) documentation from: * https://man7.org/linux/man-pages/man8/ld.so.8.html but I failed to understand when new subdirectories are being added to ld.so ? In my own very selfish interest I would like to request a new search subdirectory for riscv64 with V-extensions. (-march=rv64gcv1p0), so I would like to hear about this process. Thanks,
