This commit enhances the cond_move_process_if_block function in the GCC ifcvt pass by utilizing auto_vec for register lists. Previously, these lists were raw vec<rtx> requiring explicit cleanup via a goto label upon failure. By switching to auto_vec, the cleanup label, flag, and associated gotos are eliminated, resulting in cleaner code and reduced complexity without altering the pass’s functionality.
