btw., why does this printout SHOUT the 'or'? It's certainly not an 
important piece of information. Something like:

   vec-adds | add                          [Hardware vector event]
   vec-muls | multiply                     [Hardware vector event]
   vec-divs | divide                       [Hardware vector event]
   vec-idle-cycles | vec-empty-cycles      [Hardware vector event]
   vec-stall-cycles | vec-busy-cycles      [Hardware vector event]
   vec-ops | vec-operations                [Hardware vector event]

looks better on all levels.
