;; ??? Should prepend a * to all pattern names which are not used.
;; This will make the compiler smaller, and rebuilds after changes faster.

;; ??? Should be enhanced to include support for many more GNU superoptimizer
;; sequences.  Especially the sequences for arithmetic right shifts.

;; ??? Should check all DImode patterns for consistency and usefulness.

;; ??? The MAC.W and MAC.L instructions are not supported.  There is no
;; way to generate them.

;; ??? The cmp/str instruction is not supported.  Perhaps it can be used
;; for a str* inline function.

;; BSR is not generated by the compiler proper, but when relaxing, it
;; generates .uses pseudo-ops that allow linker relaxation to create
;; BSR.  This is actually implemented in bfd/{coff,elf32}-sh.c

;; reload when the constant is too large for a reg+offset address.

;; ??? We would get much better code if this was done in reload.  This would
;; require modifying find_reloads_address to recognize that if the constant
;; is out-of-range for an immediate add, then we get better code by reloading
;; the constant into a register than by reloading the sum into a register,
;; since the former is one instruction shorter if the address does not need
;; to be offsettable.  Unfortunately this does not work, because there is
;; only one register, r0, that can be used as an index register.  This register
;; is also the function return value register.  So, if we try to force reload
;; to use double-reg addresses, then we end up with some instructions that
;; need to use r0 twice.  The only way to fix this is to change the calling
;; convention so that r0 is not used to return values.
