Author: spop Date: Thu Aug 17 13:14:26 2006 New Revision: 116223 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=116223 Log: PR middle-end/25211 PR middle-end/20256 PR middle-end/26435 * tree-loop-linear.c (linear_transform_loops): Don't test perfect_nest_p. Call rewrite_into_loop_closed_ssa only when something changed. * lambda.h (gcc_loopnest_to_lambda_loopnest): Update declaration. * lambda-code.c (can_convert_to_perfect_nest): Declared. (gcc_loopnest_to_lambda_loopnest): Removed need_perfect_nest parameter. Test for perfect_nest_p here. Fix formating. (replace_uses_equiv_to_x_with_y): Fix formating. (stmt_uses_op): Removed. (can_convert_to_perfect_nest): Removed loopivs parameter. Complete the test by checking the scalar dependences. (perfect_nestify): Remove the test for can_convert_to_perfect_nest. Fix formating. Don't copy statements in the inner loop: move them to the inner loop header.
