/* Currently, the only users of the USE_*CREMENT macros are
move_by_pieces / store_by_pieces_1 . We don't want them to use
POST_MODIFY modes, because we got ample addressing range for the
reg+offset addressing mode; besides, there are short index+offset loads,
but the only short post-modify load uses POST_MODIFY_REG.
Moreover, using auto-increment in move_by_pieces from structure copying
in the prologue causes confused debug output.
If another pass starts using these macros where the use of these
addressing modes would make more sense, we can try checking the
current pass. */
