(sh_legitimate_index_p): Allow QImode displacements for non-SH2A. (sh_legitimize_address): Add QImode displacement handling. (sh_cannot_change_mode_class): Disallow GENERAL_REGS for SFmode vector subregs. (sh_secondary_reload): Add QImode displacement handling. * config/sh/predicates.md (movsrc_no_disp_mem_operand): New predicate. * config/sh/constraints.md (K04, Snd, Sdd): New constraints. * config/sh/sh.md (extendqisi2): Remove constraints from expander. (*extendqisi2_compact): Rename to *extendqisi2_compact_reg, restrict to register operands only. (*extendqisi2_compact_mem_disp, *extendqisi2_compact_snd): New insns. (extendqihi2): Change insn to expander. (*extendqihi2_compact_reg): New insn. (movqi_i, movqi): Replace with ... (movqi, *movqi_reg_reg, *movqi_store_mem_disp12, *movqi_load_mem_disp, *movqi_load_mem_disp): ... these. Add new peepholes for QImode displacement addressing.
