; Enable all alternatives that are both arch_enabled and insn_enabled.
; FIXME:: opt_enabled has been temporarily removed till the time we have
; an attribute that allows the use of such alternatives.
; This depends on caching of speed_p, size_p on a per
; alternative basis. The problem is that the enabled attribute
; cannot depend on any state that is not cached or is not constant
; for a compilation unit. We probably need a generic "hot/cold"
; alternative which if implemented can help with this. We disable this
; until such a time as this is implemented and / or the improvements or
; regressions with removing this attribute are double checked.
; See ashldi3_neon and <shift>di3_neon in neon.md.
