* config/sh/sh.c (max_mov_insn_displacement, disp_addr_displacement):
Prefix function names with 'sh_'. Make them non-static.
* config/sh/sh-protos.h (sh_disp_addr_displacement,
sh_max_mov_insn_displacement): Add declarations.
* config/sh/constraints.md (Q): Reject QImode.
(Sdd): Use match_code "mem".
(Snd): Fix erroneous matching of non-memory operands.
* config/sh/predicates.md (short_displacement_mem_operand): New
predicate.
(general_movsrc_operand): Disallow PC relative QImode loads.
* config/sh/sh.md (*mov<mode>_reg_reg): Remove it.
(*movqi, *movhi): Merge both insns into...
(*mov<mode>): ... this new insn. Replace generic 'm' constraints with
'Snd' and 'Sdd' constraints. Calculate insn length dynamically based
on the operand types.
