re PR tree-optimization/50789 (Gather vectorization)
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<mode>, *avx2_gathersi<mode>): Use <VEC_GATHER_IDXSI>
instead of <VEC_GATHER_MODE>.
(avx2_gatherdi<mode>): Use <VEC_GATHER_IDXDI> instead of
<<AVXMODE48P_DI> and <VEC_GATHER_SRCDI> instead of VEC_GATHER_MODE
on src and mask operands.
(*avx2_gatherdi<mode>): Likewise. Use VEC_GATHER_MODE iterator
instead of AVXMODE48P_DI.
(avx2_gatherdi<mode>256, *avx2_gatherdi<mode>256): 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.
