;; FIXME: These fmac combine pass assisting specifics are obsolete since
;; we now use the FMA patterns, which do not depend on the combine
;; pass anymore.
;; Unfortunately, the combiner is unable to cope with the USE of the FPSCR
;; register in feeding fp instructions. Thus, in order to generate fmac,
;; we start out with a mulsf pattern that does not depend on fpscr.
;; This is split after combine to introduce the dependency, in order to
;; get mode switching and scheduling right.
