From 6354ec2d16e0af4d8f7928e543d662338c3a9ab2 Mon Sep 17 00:00:00 2001 From: dnovillo Date: Wed, 23 Jun 2004 20:12:44 +0000 Subject: * Makefile.in (tree-vn.o): New. (tree-ssa-pre.o): Don't depend on RTL_H. * tree-dfa.c (find_referenced_vars): Don't call init_tree_ssa. * tree-flow.h (struct var_ann_d): Remove field expr_set. (add_to_value, expressions_equal_p, get_value_handle, vn_compute, vn_lookup_or_add, vn_add, vn_lookup, vn_init, vn_delete): Declare. * tree-optimize.c (execute_init_datastructures): New local function. (pass_init_datastructures): New local variable. (init_tree_optimization_passes): Sequence pass_init_datastructures. * tree-pretty-print.c (MASK_POINTER): Remove. (dump_generic_node): Handle VALUE_HANDLE. * tree-ssa-pre.c: Move all value numbering routines to tree-vn.c. Update callers to use new function names. Use VALUE_HANDLE_ID and VALUE_HANDLE_EXPR_SET instead of variable annotations. * tree-ssa.c (init_tree_ssa): Call vn_init. (delete_tree_ssa): Call vn_delete. * tree-vn.c: New file. * tree.c (tree_size): Handle VALUE_HANDLE. (tree_node_structure): Likewise. (iterative_hash_expr): Likewise. * tree.def (VALUE_HANDLE): New code. * tree.h (struct tree_value_handle): New. (VALUE_HANDLE_ID): Define. (VALUE_HANDLE_EXPR_SET): Define. (enum tree_node_structure_enum): Add TS_VALUE_HANDLE. (union tree_node): Add struct tree_value_handle. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@83564 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/tree-optimize.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'gcc/tree-optimize.c') diff --git a/gcc/tree-optimize.c b/gcc/tree-optimize.c index 30e1e7c25ef..a9217b187c4 100644 --- a/gcc/tree-optimize.c +++ b/gcc/tree-optimize.c @@ -153,6 +153,33 @@ static struct tree_opt_pass pass_free_datastructures = 0 /* todo_flags_finish */ }; + +/* Do the actions required to initialize internal data structures used + in tree-ssa optimization passes. */ + +static void +execute_init_datastructures (void) +{ + /* Allocate hash tables, arrays and other structures. */ + init_tree_ssa (); +} + +static struct tree_opt_pass pass_init_datastructures = +{ + NULL, /* name */ + NULL, /* gate */ + execute_init_datastructures, /* execute */ + NULL, /* sub */ + NULL, /* next */ + 0, /* static_pass_number */ + 0, /* tv_id */ + PROP_cfg, /* properties_required */ + 0, /* properties_provided */ + 0, /* properties_destroyed */ + 0, /* todo_flags_start */ + 0 /* todo_flags_finish */ +}; + /* Iterate over the pass tree allocating dump file numbers.
