tree-loop-linear.c: Include obstack.h. 

2007-09-06  Laurynas Biveinis  <laurynas.biveinis@gmail.com>

	* tree-loop-linear.c: Include obstack.h.
	(linear_transform_loops): New obstack lambda_obstack.
	Initialize it, pass it to gcc_loopnest_to_lambda_loopnest,
	lambda_loopnest_transform, lambda_loopnest_to_gcc_loopnest calls
	and free afterwards.
	* lambda.h (struct obstack): New forward declaration.
	(lambda_linear_expression_new): New parameter of type struct
	obstack *.
	(lambda_loopnest_new): Likewise.
	(lambda_loopnest_transform): Likewise.

	allocation of ret.
	(lambda_body_vector_new): Likewise.
	(lambda_linear_expression_new): Likewise.
	(lambda_lattice_new): Likewise.
	(lambda_loopnest_new): Likewise.  Additionally use obstack to
	allocate LN_LOOPS(ret).

	it to lambda_lattice_new.
	(lambda_body_vector_compute_new): New parameter lambda_obstack.
	Pass it to lambda_body_vector_new.
	(lambda_lattice_compute_base): New paramater lambda_obstack.  Pass
	it to lambda_lattice_new.
	(compute_nest_using_fourier_motzkin): New parameter lambda_obstack.
	Pass it to lambda_loopnest_new, lambda_linear_expression_new.
	(lambda_compute_target_space): Likewise.
	(lambda_compute_auxillary_space): New parameter lambda_obstack.
	Pass it to lambda_lattice_compute_base and
	compute_nest_using_fourieer_motzkin.
	(lambda_loopnest_transform): New parameter lambda_obstack.  Pass
	it to lambda_lattice_compute_base, lambda_lattice_auxillary_space

	(gcc_tree_to_linear_expression): Nex parameter lambda_obstack.
	Pass it to lambda_linear_expression_new.
	(gcc_loop_to_lambda_loop): New parameter lambda_obstack.  Pass it
	to gcc_tree_to_linear_expression.
	(gcc_loopnest_to_lambda_loopnest): New parameter lambda_obstack.
	Pass it to gcc_loop_to_lambda_loop and lambda_loopnest_new.
	(lambda_loopnest_to_gcc_loopnest): New parameter lambda_obstack.
	Pass it to lambda_body_vector_new and
	lambda_body_vector_compute_new.
	* Makefile.in (tree-loop-linear.o): Add $(OBSTACK_H) dependency.
