* config/tc-xtensa.c (xtensa_mark_literal_pool_location): Remove
"move_labels" argument and corresponding call to xtensa_move_labels. (md_assemble): Add a separate call to xtensa_move_labels and remove argument for call to xtensa_mark_literal_pool_location. (xtensa_literal_position, xtensa_switch_to_literal_fragment): Fix calls to xtensa_mark_literal_pool_location. (xtensa_create_local_symbol): Delete and inline the code into... (xtensa_create_literal_symbol): ...here. (xtensa_frob_label): Combine conditionals. (expression_maybe_register, xtensa_symbol_new_hook, fix_new_exp_in_seg): Use symbol_get_tc.
