Yes, here is the source for 8 double precision logs (with avx512) in glibc, for example: https://github.molgen.mpg.de/git-mirror/glibc/blob/20003c49884422da7ffb

The "sysdeps/x86_64/fpu/multiarch" directory contains many of these functions. You'll need at least GCC 8 to use them automatically, as well as the -ffast-math flag: https://godbolt.org/z/PL26up https://godbolt.org/z/PL26up
