[multiple changes]
2004-09-16 Daniel Berlin <dberlin@dberlin.org>
* cfgloop.h (duplicate_loop): Add prototype.
* cfgloopmanip.c (duplicate_loop): Make non-static.
* lambda-code.c (perfect_nestify): Factor out test whether
we can handle this loop into separate function.
Call it.
(can_convert_to_perfect_nest): New function.
(replace_uses_of_x_with_y): Add modify_stmt call.
* tree-loop-linear.c (linear_transform_loops): Call
rewrite_into_loop_closed_ssa and free_df.
2004-09-16 Daniel Berlin <dberlin@dberlin.org>
* lambda-code.c (invariant_in_loop): is_gimple_min_invariant is
loop invariant as well.
(perfect_nestify): new function.
(gcc_loop_to_lambda_loop): New parameters to track lower bounds,
upper bounds, and steps.
Set outerinductionvar properly.
(gcc_loopnest_to_lambda_loopnest): Add loops and need_perfect
parameters.
Return NULL if we need a perfect loop and can't make one.
(lambda_loopnest_to_gcc_loopnest): Correct algorithm.
(not_interesting_stmt): New function.
(phi_loop_edge_uses_def): Ditto.
(stmt_uses_phi_result): Ditto.
(stmt_is_bumper_for_loop): Ditto.
(perfect_nest_p): Ditto.
(nestify_update_pending_stmts): Ditto.
(replace_uses_of_x_with_y): Ditto.
(stmt_uses_op): Ditto.
(perfect_nestify): Ditto.
* lambda-mat.c (lambda_matrix_id_p): New function.
* lambda-trans.c (lambda_trans_matrix_id_p): Ditto.
* lambda.h: Update prototypes.
* tree-loop-linear (linear_transform_loop): Use new
perfect_nest_p. Detect and ignore identity transform.
* tree-ssa-loop.c (pass_linear_transform): Use TODO_write_loop_closed.
2004-09-16 Sebastian Pop <pop@cri.ensmp.fr>
* tree-loop-linear.c (gather_interchange_stats): Add more comments.
Gather also strides of accessed data. Pass in the data references
array.
(try_interchange_loops): Add a new heuristic for handling the temporal
locality. Pass in the data references array.
(linear_transform_loops): Pass the data references array to
try_interchange_loops.
