This was around in my tree for some time, consolidates calling add_referenced_vars into vect_get_new_vect_var. Also uses create_tmp_reg consistently.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied. Richard. 2012-07-17 Richard Guenther <rguent...@suse.de> * tree-vect-data-refs.c (vect_get_new_vect_var): Add referenced vars here, use create_tmp_reg where appropriate. (vect_create_addr_base_for_vector_ref): Do not add referenced vars here, use create_tmp_reg where appropriate. (vect_create_data_ref_ptr): Likewise. (vect_create_destination_var): Likewise. (vect_permute_store_chain): Likewise. (vect_permute_load_chain): Likewise. * tree-vect-loop-manip.c (vect_create_cond_for_align_checks): Likewise. * tree-vect-loop.c (get_initial_def_for_induction): Likewise. * tree-vect-patterns.c (vect_recog_temp_ssa_var): Likewise.
