--- Comment #2 from ktkachov at gcc dot gnu.org ---
I can't reproduce the ICE with the testcase.
My arm-none-eabi with -mcpu=cortex-a9 -mfloat-abi=hard  -mfpu=neon -O2
generates:
        .cpu cortex-a9
        .eabi_attribute 28, 1
        .eabi_attribute 20, 1
        .eabi_attribute 21, 1
        .eabi_attribute 23, 3
        .eabi_attribute 24, 1
        .eabi_attribute 25, 1
        .eabi_attribute 26, 1
        .eabi_attribute 30, 2
        .eabi_attribute 34, 1
        .eabi_attribute 18, 4
