2004-10-16 Daniel Berlin <dberlin@dberlin.org> Fix PR tree-optimization/17672 Fix PR tree-optimization/18168 * lambda-code.c (lambda_lattice_compute_base): Fix reversed assert test. (gcc_tree_to_linear_expression): Add extra to existing constant. (depth_of_nest): Factor out function used in various places. (gcc_loop_to_lambda_loop): Clean up code a little bit. No functional changes. (find_induction_var_from_exit_cond): Stop guessing, and just get the right answer :). (gcc_loopnest_to_lambda_loopnest): Remove useless pre-allocation. Print out message about result of attempt to create perfect nest. (lbv_to_gcc_expression): Add type argument, use it to do math and induction variable creation. (lle_to_gcc_expression): Ditto. (lambda_loopnest_to_gcc_loopnest): Create new iv with same type as oldiv. Pass type argument to lle_to_gcc_expression and lbv_to_gcc_expression. Reset number of iterations after transformation. (perfect_nestify): Remove useless pre-allocation, and cleanup a small amount. * tree-data-ref.c (build_classic_dist_vector): Return false for dependences completely outside of the loop nest we asked about. (build_classic_dir_vector): Ditto. (compute_data_dependences_for_loop): Only add dependence relations inside the loop we asked about. * tree-loop-linear.c (linear_transform_loops): Use DDR_SIZE_VECT. Compute immediate uses. * tree-optimize.c: Move linear_transform_loops to before ivcanon. From-SVN: r89945 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
