--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:ebdfd1606da6b5aa586b0cd156b69b659235c9c2 commit r11-5821-gebdfd1606da6b5aa586b0cd156b69b659235c9c2 Author: Richard Biener <rguent...@suse.de> Date: Thu Dec 3 10:25:14 2020 +0100 tree-optimization/98113 - vectorize a sequence of BIT_INSERT_EXPRs This adds the capability to handle a sequence of vector BIT_INSERT_EXPRs to be vectorized similar as to how we vectorize vector constructors. 2020-12-03 Richard Biener <rguent...@suse.de> PR tree-optimization/98113 * tree-vectorizer.h (struct slp_root): New. (_bb_vec_info::roots): New member. * tree-vect-slp.c (vect_analyze_slp): Also walk BB info roots. (_bb_vec_info::_bb_vec_info): Adjust. (_bb_vec_info::~_bb_vec_info): Likewise. (vld_cmp): New. (vect_slp_is_lane_insert): Likewise. (vect_slp_check_for_constructors): Match a series of BIT_INSERT_EXPRs as vector constructor. (vect_slp_analyze_bb_1): Continue if BB info roots is not empty. (vect_slp_analyze_bb_1): Mark the whole BIT_INSERT_EXPR root sequence as pure_slp. * gcc.dg/vect/bb-slp-70.c: New testcase.
