--- Comment #31 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Jakub Jelinek from comment #28) > Which will likely penalize even code where the stv pass wouldn't do anything. > Isn't it better to just disable the stv pass if the stack isn't aligned > enough Maybe we can use HJ's patch from Comment #27 and communicate converted_insns flag from convert_scalars_to_vector to ix86_finalize_stack_realign_flags? The i_f_s_r function is able to cancel the realignment just before prologue generation, when realignment is not needed.
