URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=125030
Log:
* doc/passes.texi: Document predictive commoning.

* tree-pretty-print.c (op_symbol_1): Renamed to ...
(op_symbol_code): ... and exported.
(dump_omp_clause, op_symbol): Use op_symbol_code
instead of op_symbol_1.
* tree-pass.h (pass_predcom): Declare.
* timevar.def (TV_PREDCOM): New timevar.
* tree-ssa-loop.c (run_tree_predictive_commoning,
gate_tree_predictive_commoning, pass_predcom): New.
* tree-data-ref.c (find_data_references_in_loop): Find the
references in dominance order.
(canonicalize_base_object_address): Ensure that the result has
pointer type.
(dr_analyze_innermost): Export.
(create_data_ref): Code to fail for references with invariant
address moved ...
(find_data_references_in_stmt): ... here.
* tree-data-ref.h (dr_analyze_innermost): Declare.
* tree-affine.c: Include tree-gimple.h and hashtab.h.
(aff_combination_find_elt, name_expansion_hash,
name_expansion_eq, tree_to_aff_combination_expand,
double_int_constant_multiple_p, aff_combination_constant_multiple_p):
New functions.
* tree-affine.h (aff_combination_constant_multiple_p,
tree_to_aff_combination_expand): Declare.
* tree-predcom.c: New file.

stmt_dominates_stmt_p, get_lsm_tmp_name): Declare.
* Makefile.in (tree-predcom.o): Add.
(tree-affine.o): Add TREE_GIMPLE_H dependency.
* passes.c (init_optimization_passes): Add dceloop after
copy propagation in loop optimizer. Add predictive commoning
to loop optimizer passes.
* gcc.dg/tree-ssa/predcom-1.c: New test.
* gcc.dg/tree-ssa/predcom-2.c: New test.
* gcc.dg/tree-ssa/predcom-3.c: New test.
* gcc.dg/tree-ssa/predcom-4.c: New test.
