(calc_live_regs): Add FPSCR_MODES_REG and FPSCR_STAT_REG to the ignore list. (emit_sf_insn, emit_df_insn, expand_sf_unop, expand_sf_binop, expand_df_unop, expand_df_binop): Remove. (sh_conditional_register_usage): Mark FPSCR_MODES_REG and FPSCR_STAT_REG as not call clobbered. (sh_emit_mode_set): Emit fpscr store-modify-load sequence instead of invoking fpscr_set_from_mem. * config/sh/sh.h (MAX_REGISTER_NAME_LENGTH): Increase to 6. (SH_REGISTER_NAMES_INITIALIZER): Add names for FPSCR_MODES_REG and FPSCR_STAT_REG. (REGISTER_NAMES): Adjust. (SPECIAL_REGISTER_P): Add FPSCR_MODES_REG and FPSCR_STAT_REG. (FIRST_PSEUDO_REGISTER): Increase to 156. (DWARF_FRAME_REGISTERS): Define as 153 to keep the original value. (FIXED_REGISTERS, CALL_USED_REGISTERS): Add FPSCR_MODES_REG and FPSCR_STAT_REG. (REG_CLASS_CONTENTS): Adjust ALL_REGS bit mask to include FPSCR_MODES_REG and FPSCR_STAT_REG. (REG_ALLOC_ORDER): Add FPSCR_MODES_REG and FPSCR_STAT_REG. * config/sh/sh.md (FPSCR_MODES_REG, FPSCR_STAT_REG, FPSCR_PR, FPSCR_SZ): Add new constants. (UNSPECV_FPSCR_MODES, UNSPECV_FPSCR_STAT): Add new unspecv constants. (movpsi): Use TARGET_FPU_ANY condition, invoke gen_fpu_switch. (fpu_switch): Add use and set of FPSCR_STAT_REG and FPSCR_MODES_REG. Use TARGET_FPU_ANY condition. (fpu_switch peephole2): Remove. (fpu_switch split): Use simple_mem_operand to capture the mem and adjust split implementation. (extend_psi_si, truncate_si_psi): New insns. (toggle_sz, toggle_pr): Use FPSCR_SZ, FPSCR_PR constants. Add set of FPSCR_MODES_REG.
