; Some of these patterns can be matched as SSE min or max. Some of
; then can be matched provided that the operands are swapped.
; Some of them can't be matched at all and require a comparison
; and a conditional branch.

; The naming convention is {,x_,y_}{o,u}{gt,lt,ge,le}{,_inverse}
; x_ : use 0.0 instead of %y
; y_ : use -0.0 instead of %y
; _inverse : swap the arms of the select.

; Some of these tests depend on -join-physregs commuting instructions to
; eliminate copies.
