Comment 13 for bug 723185

A backport to 4.6 shows the following failures -

arm-sim: gcc.c-torture/execute/loop-ivopts-2.c compilation, -O3 -fomit-frame-pointer -funroll-all-loops -finline-functions (internal compiler error)
arm-sim: gcc.c-torture/execute/loop-ivopts-2.c compilation, -O3 -fomit-frame-pointer -funroll-loops (internal compiler error)
arm-sim: gcc.c-torture/execute/loop-ivopts-2.c compilation, -O3 -fomit-frame-pointer (internal compiler error)

arm-sim: gcc.c-torture/execute/pr23135.c compilation, -O1 (internal compiler error)

 I'll dig further when I have a little more time
