2008-05-20 Jan Sjodin <jan.sjodin@amd.com> Sebastian Pop <sebastian.pop@amd.com> * 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.
