Unfortunately this patch makes gcc.dg/vect/no-scevccp-outer-{7,13}.c fail on powerpc64-linux: +FAIL: gcc.dg/vect/no-scevccp-outer-13.c execution test +FAIL: gcc.dg/vect/no-scevccp-outer-7.c execution test which is a regression from 4.8-20130502. Reverting r198580 fixes it. The same FAILs also occur on trunk. /Mikael
