Check MODES_TIEABLE_P. Use simplify_gen_subreg to convert the source to NEW_MODE and extract_low_bits to convert the shifted value to READ_MODE. (replace_read): Allow the load and store to have different mode classes. Use extract_low_bits when SHIFT == 0. Create the shift or extraction instructions before trying the replacement. Update dump-file code accordingly, avoiding use of REGNO (store_info->rhs). gcc/testsuite/ * gcc.target/mips/dse-1.c: Add checks for zeros. From-SVN: r133452

(last_mode_for_init_move_cost): Promoted function-local static to file-scope static to make it accessible outside init_move_cost. (init_reg_sets): Do not initialize fixed_regs and call_used_regs yet. Do not initialize inv_reg_alloc_order yet, either. Do initialize reg_names since it is needed for parsing command-line options. (init_move_cost): Use last_mode_for_init_move_cost instead of function-local static. (init_reg_sets_1): Initialize fixed_regs, call_used_regs, and call_really_used_regs now. Reinitialize reg_names. Also initialize inv_reg_alloc_order. Zero reg_class_subunion and reg_class_superunion. Clear losing_caller_save_reg_set. Preserve global registers if called more than once. Reset move cost, may_move_in_cost, may_move_out_cost, and last_mode_for_init_move_cost. (init_reg_modes_target): Renamed from init_reg_modes_once, since it can now be invoked more than once. Update comments. (init_regs): Update comments. (fix_register): Update initial_fixed_regs, initial_call_used_regs, and initial_call_really_used_regs, instead of the non-initial variables. This allows us to save the command-line register settings after target reinitialization. (init_reg_autoinc): Zero forbidden_inc_dec_classes. * rtl.h (init_emit_regs): Declare.
