; This has two compatible regions based on function attributes.  We have
; attributes that should be transferred only if it is on all of the regions.

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