--- Comment #3 from Joseph S. Myers <jsm28 at gcc dot gnu.org> --- libquadmath is legacy code, using the actual C23 interfaces in current glibc is preferred (although if someone does want to add more functions to libquadmath anyway for use on non-glibc and older-glibc systems, libquadmath does now have a script I added in 2018 to automate the updates of libm code from glibc, to which one could add more files to the list taken from glibc and make whatever updates are needed to work with all the changes that have taken place in glibc since 2018).
