re PR tree-optimization/28937 (ICE in add_virtual_operand, at tree-ssa-operands.c:1309)
2006-09-05 Andrew Pinski <pinskia@physics.uc.edu> PR tree-opt/28937 * tree-flow.h (tree_ssa_unswitch_loops): Return unsigned int. (canonicalize_induction_variables): Likewise. (tree_unroll_loops_completely): Likewise. (tree_ssa_prefetch_arrays): Likewise. (remove_empty_loops): Likewise. * tree-ssa-loop-unswitch.c (tree_ssa_unswitch_loops): Return TODO_cleanup_cfg instead of directly calling cleanup_tree_cfg_loop. * tree-ssa-loop-ivcanon.c (canonicalize_induction_variables): Likewise.
