--- Comment #10 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> --- For power, the patch enables -funroll-loops (with small loops unroller in RTL) and which also enabled the 'cunroll'(complete unroller) on tree. For this loop(the inner loop), 'cunroll' figures out that the loop is executed at most 13 times. Then the complete unroller could handle this loop.
