I don't believe this. I only know that all the test cases considered
by me have the same problem.
Could you please explain what is 'reduction'? I've found out that,
according to the comment of the rewrite_reductions_out_of_ssa (this
function duplicates pbbs), the rewrite_reductions_out_of_ssa rewrite
out of SSA all the reduction phi nodes of SCOP. What are reduction phi
nodes? How are they related to 'reduction'?
