No matching function for call to 'bitfieldExtract' on Android.

    uint mask = (1u << numBits) - 1u;
    uint value = (data >> offset) & mask;

    Code above seem to be optimized as an function call named 'bitfieldExtract' when shader compiling. Such function can't be found on my android phone, and so do the Mumu android simulator.

    I print some device info.
