7 ; This includes the attributes, no-nans-fp-math,
8 ; no-signed-zeros-fp-math, less-precise-fpmad, unsafe-fp-math, and
9 ; no-infs-fp-math. Only when each instance of similarity has these attributes
10 ; can we say that the outlined function can have these attributes since that
11 ; is the more general case for these attributes.
