Hi,
    I compile skia for arm and this bug pop out. And after scope out a while, I
think the auto key word drop the attribute pcs("aapcs-vfp").
    The attachment is the code reproduce this bug.
    Before enable the macro RIGHT_CODE, the function call uses r2 r3 as
argument passing register. After enable the macro RIGHT_CODE, the function call
uses neon registers only.
