;; ??? register_operand accepts (subreg:DI (mem:SI X)) which forces later ;; reload. This will be fixed once scheduling support is turned on.
;; ??? Optimize for post-increment addressing modes.
;; ??? fselect is not supported, because there is no integer register ;; equivalent.
;; ??? fp abs/min/max instructions may also work for integer values.
;; ??? Would a predicate_reg_operand predicate be useful? The HP one is buggy, ;; it assumes the operand is a register and takes REGNO of it without checking.
;; ??? Would a branch_reg_operand predicate be useful? The HP one is buggy, ;; it assumes the operand is a register and takes REGNO of it without checking.
;; ??? Go through list of documented named patterns and look for more to ;; implement.
;; ??? Go through instruction manual and look for more instructions that ;; can be emitted.
;; ??? Add function unit scheduling info for Itanium (TM) processor.
;; ??? Need a better way to describe alternate fp status registers.
