-;; Many logical operations should have "bit" variants if only one
-;; bit is going to be operated on.
-
-;; (and (logical op) (const_int X))
-;; If const_int only specifies a few bits (like a single byte in a 4 byte
-;; operation, then it's more efficient to only apply the and and logical_op
-;; to the bits we care about.
-
;; Some of the extend instructions accept a general_operand_src, which
;; allows all the normal memory addressing modes. The length computations
;; don't take this into account. The lengths in the MD file should be
;; "worst case" and then be adjusted to their correct values by
;; h8300_adjust_insn_length.
-;; On the h8300h, adds/subs operate on the 32bit "er" registers. Right
-;; now GCC doesn't expose the "e" half to the compiler, so using add/subs
-;; for addhi and subhi is safe.
-;; Long term, we want to expose the "e" half to the compiler (gives us
-;; 8 more 16bit registers). At that point addhi and subhi can't use adds/subs.

;; There's currently no way to have a insv/extzv expander for the H8/300H
