re PR tree-optimization/34683 (SSA rewriting in the loop unroller causes quadratic behavior)
2008-01-10 Richard Guenther <rguenther@suse.de>
PR middle-end/34683
* tree-cfg.c (tree_merge_blocks): Do not go through the
full-blown folding and stmt updating path if we just deal
with virtual operands.
* tree-ssa-copy.c (may_propagate_copy): Do not short-cut
test for abnormal SSA_NAMEs.
From-SVN: r131446
