FAIL: gcc.dg/vect/vect-outer-5.c (internal compiler error)
Compiler configured with:
Configured with: $SOURCE/gcc/configure --target=arm-none-eabi

ICE triggered for me with the command:
arm-none-eabi-gcc -fno-diagnostics-show-caret -ffast-math -ftree-vectorize
-fno-vect-cost-model -fno-common -O2 -fdump-tree-vect-details -S vect-outer-5.i
caused by r196770.
I believe Richard already has a patch queued to fix this
