From b0eb8c663b1bca6c460b0a6754fd8c49ca018266 Mon Sep 17 00:00:00 2001 From: dorit Date: Sun, 19 Aug 2007 12:02:48 +0000 Subject: * tree-data-refs.c (split_constant_offset): Expose. * tree-data-refs.h (split_constant_offset): Add declaration. * tree-vectorizer.h (dr_alignment_support): Renamed dr_unaligned_software_pipeline to dr_explicit_realign_optimized. Added a new value dr_explicit_realign. (_stmt_vec_info): Added new fields: dr_base_address, dr_init, dr_offset, dr_step, and dr_aligned_to, along with new access functions for these fields: STMT_VINFO_DR_BASE_ADDRESS, STMT_VINFO_DR_INIT, STMT_VINFO_DR_OFFSET, STMT_VINFO_DR_STEP, and STMT_VINFO_DR_ALIGNED_TO. * tree-vectorizer.c (vect_supportable_dr_alignment): Add documentation. In case of outer-loop vectorization with non-fixed misalignment - use the dr_explicit_realign scheme instead of the optimized realignment scheme. (new_stmt_vec_info): Initialize new fields. * tree-vect-analyze.c (vect_compute_data_ref_alignment): Handle the 'nested_in_vect_loop' case. Change verbosity level. (vect_analyze_data_ref_access): Handle the 'nested_in_vect_loop' case. Don't fail on zero step in the outer-loop for loads. (vect_analyze_data_refs): Call split_constant_offset to calculate base, offset and init relative to the outer-loop. * tree-vect-transform.c (vect_create_data_ref_ptr): Replace the unused BSI function argument with a new function argument - at_loop. Simplify the condition that determines STEP. Takes additional argument INV_P. Support outer-loop vectorization (handle the nested_in_vect_loop case), including zero step in the outer-loop. Call vect_create_addr_base_for_vector_ref with additional argument. (vect_create_addr_base_for_vector_ref): Takes additional argument LOOP. Updated function documentation. Handle the 'nested_in_vect_loop' case. Fixed and simplified calculation of step. (vectorizable_store): Call vect_create_data_ref_ptr with loop instead of bsi, and with additional argument. Call bump_vector_ptr with additional argument. Fix typos. Handle the 'nested_in_vect_loop' case. (vect_setup_realignment): Takes additional arguments INIT_ADDR and DR_ALIGNMENT_SUPPORT. Returns another value AT_LOOP. Handle the case when the realignment setup needs to take place inside the loop. Support the dr_explicit_realign scheme. Allow generating the optimized realignment scheme for outer-loop vectorization. Added documentation. (vectorizable_load): Support the dr_explicit_realign scheme. Handle the 'nested_in_vect_loop' case, including loads that are invariant in the outer-loop and the realignment schemes. Handle the case when the realignment setup needs to take place inside the loop. Call vect_setup_realignment with additional arguments. Call vect_create_data_ref_ptr with additional argument and with loop instead of bsi. Fix 80-column overflow. Fix typos. Rename PHI_STMT to PHI. (vect_gen_niters_for_prolog_loop): Call vect_create_addr_base_for_vector_ref with additional arguments. (vect_create_cond_for_align_checks): Likewise. (bump_vector_ptr): Updated to support the new dr_explicit_realign scheme: takes additional argument bump; argument ptr_incr is now optional; updated documentation. (vect_init_vector): Takes additional argument (bsi). Use it, if available, to insert the vector initialization. (get_initial_def_for_induction): Pass additional argument in call to vect_init_vector. (vect_get_vec_def_for_operand): Likewise. (vect_setup_realignment): Likewise. (vectorizable_load): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@127624 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-data-ref.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'gcc/tree-data-ref.h') diff --git a/gcc/tree-data-ref.h b/gcc/tree-data-ref.h index 99f8b23f138..2ae58266db6 100644 --- a/gcc/tree-data-ref.h +++ b/gcc/tree-data-ref.h @@ -388,4 +388,7 @@ index_in_loop_nest (int var, VEC (loop_p, heap) *loop_nest) /* In lambda-code.c */ bool lambda_transform_legal_p (lambda_trans_matrix, int, VEC (ddr_p, heap) *); +/* In tree-data-refs.c */ +void split_constant_offset (tree , tree *, tree *); + #endif /* GCC_TREE_DATA_REF_H */ -- cgit v1.2.1
