    I am using an ARM NEON library, which has several similar function declaration:

    void ne10_fir_float_neon (const ne10_fir_instance_f32_t *S, ne10_float32_t *pSrc, ne10_float32_t *pDst, ne10_uint32_t blockSize) asm("ne10_fir_float_neon")

    "ne10_fir_float_neon" shows two times above. I cannot understand it. Could you explain it to me?

  2. The asm call isn't a function definition; it's a directive to insert the
    specified text into the assembly language generated by the compiler.

    In order to get a more detailed answer than that, you need to show us the
    context around the asm statement.
