tree-vect-loop.c (vect_analyze_loop_operations): Also call vectorizable_reduction for vect_double_reduction_def.
2019-09-26 Richard Biener <rguenther@suse.de>
* tree-vect-loop.c (vect_analyze_loop_operations): Also call
vectorizable_reduction for vect_double_reduction_def.
(vect_transform_loop): Likewise.
(vect_create_epilog_for_reduction): Move double-reduction
PHI creation and preheader argument setting of PHIs ...
(vectorizable_reduction): ... here. Also process
vect_double_reduction_def PHIs, creating the vectorized
PHI nodes, remembering the scalar adjustment computed for
the epilogue in STMT_VINFO_REDUC_EPILOGUE_ADJUSTMENT.
Remember the original reduction code in STMT_VINFO_REDUC_CODE.
* tree-vectorizer.c (vec_info::new_stmt_vec_info):
Initialize STMT_VINFO_REDUC_CODE.
* tree-vectorizer.h (_stmt_vec_info::reduc_epilogue_adjustment): New.
(_stmt_vec_info::reduc_code): Likewise.
(STMT_VINFO_REDUC_EPILOGUE_ADJUSTMENT): Likewise.
(STMT_VINFO_REDUC_CODE): Likewise.
