This patch makes dr_aux link back to both the scalar data_reference and the containing stmt_vec_info, so that it becomes a suitable key for a vectorisable reference. The data_reference link is just STMT_VINFO_DATA_REF, moved here from _stmt_vec_info. The stmt pointer is a new field and always tracks the current stmt_vec_info for the reference (which might be a pattern stmt or the original stmt). The patch also makes the dr_aux in this current stmt be the one that counts, rather than have the information stay with the DR_STMT. A new macro (STMT_VINFO_DR_INFO) gives this information for a given stmt_info. In future we could make dr_aux a separate structure, which would be useful if we want to support multiple data references per stmt. That seems too much of a diversion for this series though. 2018-07-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vectorizer.h (vec_info::move_dr): New member function. (dataref_aux): Rename to... (dr_vec_info): ...this and add "dr" and "stmt" fields. (_stmt_vec_info::dr_aux): Update accordingly. (_stmt_vec_info::data_ref_info): Delete. (STMT_VINFO_GROUPED_ACCESS, DR_GROUP_FIRST_ELEMENT) (DR_GROUP_NEXT_ELEMENT, DR_GROUP_SIZE, DR_GROUP_STORE_COUNT) (DR_GROUP_GAP, DR_GROUP_SAME_DR_STMT, REDUC_GROUP_FIRST_ELEMENT): (REDUC_GROUP_NEXT_ELEMENT, REDUC_GROUP_SIZE): Use dr_aux.dr instead of data_ref. (STMT_VINFO_DATA_REF): Likewise. Turn into an lvalue. (STMT_VINFO_DR_INFO): New macro. (DR_VECT_AUX): Use STMT_VINFO_DR_INKFO and vect_dr_stmt. (set_dr_misalignment): Update after rename of dataref_aux. (vect_dr_stmt): Move earlier in file. Return dr_aux.stmt. * tree-vect-stmts.c (new_stmt_vec_info): Remove redundant initialization of STMT_VINFO_DATA_REF. * tree-vectorizer.c (vec_info::move_dr): New function. * tree-vect-patterns.c (vect_recog_bool_pattern) (vect_recog_mask_conversion_pattern) (vect_recog_gather_scatter_pattern): Use it. * tree-vect-data-refs.c (vect_analyze_data_refs): Initialize the "dr" and "stmt" fields of dr_vec_info instead of STMT_VINFO_DATA_REF.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
