; There is code in the SDAG to expand FMAX/FMIN with fast flags to SELECT_CC.
; On PPC, we had SELECT_CC legalized using Promote for all vector types
; (including the type that they are all promoted to - which caused an infinite
; loop in legalization). This test just ensures that we terminate on such input.
