Reverting the following patch fixes the bug:
2005-01-14 Steven Bosscher <[EMAIL PROTECTED]>
* tree-ssa-dce.c (visited_control_parents): New sbitmap to
replace BB_VISITED uses.
(find_obviously_necessary_stmts): Don't clear BB_VISITED.
(propagate_necessity): Check the bitmap instead of BB_VISITED.
(tree_dce_done): Free visited_control_parents.
(perform_tree_ssa_dce): Allocate and clear it.
* tree-ssa-pre.c (compute_antic_aux): Make non-recursive.
(compute_antic): Iterate from here using a DFS. Use an sbitmap
instead of BB_VISITED.
