Guys,

Just to mention, if we need strength reduction, the definition that would
make me happiest would be that no new flops are introduced by it, but
some may be removed.  Then, only the people doing things like NaN traps
need worry.  I.e., 2.0*a <--> a+a and a+b-b -> a would be OK, but
3*a -> a+a+a would not be allowed . . .

Cheers,
Clint
