NOTE This library is obsolete. It was formerly used by the FORTRAN
Optimizing Preprocessor (FTNOPP). The performance benefits provided
by FTNOPP are now supplied by the compiler when you use the
+Ovectorize option with either C or Fortran programs at optimization
level 3 or above. (See “Optimizing Your Program” on page 171 for
details.) The vector library is provided for compatibility reasons only, in
/opt/fortran/old/lib/libvec.a.
For more information about the libvec routines, see the HP
FORTRAN/9000 Programmer’s Reference.
