2008-05-20 Jan Sjodin <jan.sjodin@amd.com> Sebastian Pop <sebastian.pop@amd.com> PR tree-optimization/36206 * tree-scalar-evolution.c: Remove enum INSERT_SUPERLOOP_CHRECS, FOLD_CONVERSIONS. (instantiate_scev_1): Rename flags to fold_conversions. Do not check for INSERT_SUPERLOOP_CHRECS, keep SSA_NAMEs defined outeside instantiation_loop. * tree-chrec.h (evolution_function_is_affine_in_loop): New. (evolution_function_is_affine_or_constant_p): Removed. * tree-data-ref.c (dr_analyze_indices): Replace resolve_mixers with instantiate_scev. (analyze_siv_subscript): Pass in the loop nest number. Call evolution_function_is_affine_in_loop instead of evolution_function_is_affine_p. (analyze_overlapping_iterations): Pass in the loop nest number. * tree-chrec.h (chrec_fold_op): New. * tree-data-ref.c (initialize_matrix_A): Traverse NOP_EXPR, PLUS_EXPR, and other trees. * testsuite/gfortran.dg/pr36206.f: New.
