Log message:
	* fold-const.c (operand_equal_p): Check for NULL TREE_TYPEs.
	
	* tree-cfg.c (remove_stmt): Call remove_ref.
	(disconnect_unreachable_case_labels): Do not disconnect the edge
	going to the block holding the BIND_EXPR node for the switch()
	body.
	(dump_tree_cfg): Call dump_current_function.
	
	* Makefile.in (tree-dfa.o): Depend on convert.h.
	* tree-dfa.c: Include convert.h.

	(replace_phi_arg_with): New local function.
	(replace_ref_with): New function.
	(try_replace_ref_with): Rename from replace_ref_in.
	Also look for V_USE references on the LHS of assignments.
	When replacing the callee of a CALL_EXPR, make sure that the type
	of the new callee is compatible with the old one.
	(replace_ref_r): Call operand_equal_p.
	(remove_ref): New function.
	(same_var_p): New function.
	(dump_referenced_vars): Add new flag DETAILS.  Update all users.
	(debug_referenced_vars): Likewise.
	
	* tree-ssa.c (dump_reaching_defs): Change output format.
	(set_ssa_links): Don't set def-def links for PHI nodes.
	
	* tree-ssa-ccp.c (replace_uses_in): Add new argument COMMIT.
	Update all users.
	
	* tree-optimize.c (dump_current_function): New function.
	(optimize_function_tree): Call it.
	* tree.h (dump_current_function): Declare.
	* c-decl.c (c_expand_body): Call dump_current_function.
	* tree-ssa-dce.c (tree_ssa_eliminate_dead_code): Likewise.
	* tree-ssa-pre.c (tree_perform_ssapre): Likewise.
	* tree-ssa.c (build_tree_ssa): Likewise.
	* tree-ssa-ccp.c (tree_ssa_ccp): Likewise.
	Dump variables and reaching definitions if TDF_DETAILS is set.
	
	* tree-pretty-print.c (print_call_name): Call dump_generic_node for
	NOP_EXPR operands.
	
	* tree-ssa-pre.c: Don't include c-common.h nor c-tree.h
	Replace calls to build_modify_expr with build everywhere.
	Replace calls to deep_copy_node with copy_node_r everywhere.
