svn commit: r256789 - projects/arm_eabi_vfp/lib/libc/arm/aeabi

New Revision: 256789
URL: http://svnweb.freebsd.org/changeset/base/256789

Log:
  The ARM EABI Run-time ABI defines the __aeabi_* floating-point functions to
  pass their values in the integer registers. Update the hard-float version of
  the functions to do this.
