           Summary: [ARM] mmx-2.c causes ICE when GCC is configured for
                    cortex-a5/vfpv3-d16-fp16
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED

I've noticed that gcc.target/arm/mmx-2 causes GCC to crash when GCC is
configured as:
--target=arm-none-linux-gnueabihf
--with-cpu=cortex-a5
--with-fpu=vfpv3-d16-fp16

generated reload insns per insn is achieved (90)
