Because glibc's libm is for general purpose use - striking a reasonable balance between speed, size and accuracy rather than providing lots of different variants including vector versions; it makes sense for glibc's libm to be a subset of a wider project rather than for glibc to maintain lots of code that isn't actually of use for glibc itself. And the expertise for maintaining it is somewhat different for that for most of glibc. -- Joseph S. Myers jos...@codesourcery.com
