* tree-loop-linear.c (gather_interchange_stats): Look in the access matrix,
and never look at the tree representation of the memory accesses.
(linear_transform_loops): Computes parameters and access matrices.
* tree-data-ref.c (compute_data_dependences_for_loop): Returns false when fails.
(access_matrix_get_index_for_parameter): New.
* tree-data-ref.h (struct access_matrix): New.
(AM_LOOP_NEST_NUM, AM_NB_INDUCTION_VARS, AM_PARAMETERS, AM_MATRIX,
AM_NB_PARAMETERS, AM_CONST_COLUMN_INDEX, AM_NB_COLUMNS,
AM_GET_SUBSCRIPT_ACCESS_VECTOR, AM_GET_ACCESS_MATRIX_ELEMENT,
am_vector_index_for_loop): New.
(struct data_reference): Add field access_matrix.
(DR_ACCESS_MATRIX): New.
(compute_data_dependences_for_loop): Update declaration.
(lambda_collect_parameters, lambda_compute_access_matrices): Declared.
* lambda.h (lambda_vector_vec_p): Declared.
* lambda-code.c: Depend on pointer-set.h.
(lambda_collect_parameters_from_af, lambda_collect_parameters,
av_for_af_base, av_for_af, build_access_matrix,
lambda_compute_access_matrices): New.
* Makefile.in (lambda-code.o): Depend on pointer-set.h.
