From 16dfb11221da8bb69bfcc5ca457cb6a6f145b03a Mon Sep 17 00:00:00 2001 From: jakub Date: Mon, 7 Nov 2011 15:59:07 +0000 Subject: PR tree-optimization/50789 * tree-vect-stmts.c (process_use): Add force argument, avoid exist_non_indexing_operands_for_use_p check if true. (vect_mark_stmts_to_be_vectorized): Adjust callers. Handle STMT_VINFO_GATHER_P. (gen_perm_mask): New function. (perm_mask_for_reverse): Use it. (reverse_vec_element): Rename to... (permute_vec_elements): ... this. Add Y and MASK_VEC arguments, generalize for any permutations. (vectorizable_load): Adjust caller. Handle STMT_VINFO_GATHER_P. * target.def (TARGET_VECTORIZE_BUILTIN_GATHER): New hook. * doc/tm.texi.in (TARGET_VECTORIZE_BUILTIN_GATHER): Document it. * doc/tm.texi: Regenerate. * tree-data-ref.c (initialize_data_dependence_relation, compute_self_dependence): No longer static. * tree-data-ref.h (initialize_data_dependence_relation, compute_self_dependence): New prototypes. * tree-vect-data-refs.c (vect_check_gather): New function. (vect_analyze_data_refs): Detect possible gather load data refs. * tree-vectorizer.h (struct _stmt_vec_info): Add gather_p field. (STMT_VINFO_GATHER_P): Define. (vect_check_gather): New prototype. * config/i386/i386-builtin-types.def: Add types for alternate gather builtins. * config/i386/sse.md (AVXMODE48P_DI): Remove. (VEC_GATHER_MODE): Rename mode_attr to... (VEC_GATHER_IDXSI): ... this. (VEC_GATHER_IDXDI, VEC_GATHER_SRCDI): New mode_attrs. (avx2_gathersi, *avx2_gathersi): Use instead of . (avx2_gatherdi): Use instead of < and instead of VEC_GATHER_MODE on src and mask operands. (*avx2_gatherdi): Likewise. Use VEC_GATHER_MODE iterator instead of AVXMODE48P_DI. (avx2_gatherdi256, *avx2_gatherdi256): Removed. * config/i386/i386.c (enum ix86_builtins): Add IX86_BUILTIN_GATHERALTSIV4DF, IX86_BUILTIN_GATHERALTDIV8SF, IX86_BUILTIN_GATHERALTSIV4DI and IX86_BUILTIN_GATHERALTDIV8SI. (ix86_init_mmx_sse_builtins): Create those builtins. (ix86_expand_builtin): Handle those builtins and adjust expansions of other gather builtins. (ix86_vectorize_builtin_gather): New function. (TARGET_VECTORIZE_BUILTIN_GATHER): Define. * gcc.target/i386/avx2-gather-1.c: New test. * gcc.target/i386/avx2-gather-2.c: New test. * gcc.target/i386/avx2-gather-3.c: New test. * gcc.target/i386/avx2-gather-4.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@181089 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-data-ref.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'gcc/tree-data-ref.h') diff --git a/gcc/tree-data-ref.h b/gcc/tree-data-ref.h index c55bd48a81e..0f12962fc93 100644 --- a/gcc/tree-data-ref.h +++ b/gcc/tree-data-ref.h @@ -1,5 +1,5 @@ /* Data references and dependences detectors. - Copyright (C) 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 + Copyright (C) 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011 Free Software Foundation, Inc.
