svn commit: r358348 - in head/lib/libc: . gdtoa gen sparc64 sparc64/fpu sparc64/gen sparc64/sys sys

[Warner Losh]

Author: imp
Date: Wed Feb 26 18:55:09 2020
New Revision: 358348
URL: https://svnweb.freebsd.org/changeset/base/358348

Log:
  Remove sparc64 specific parts of libc.
  
  Also update comments for which architectures use 128 bit long doubles,
  as appropriate.
  
  The softfloat specialization routines weren't updated since they
  appear to be from an upstream source which we may want to update in
  the future to get a more favorable license.
