Hi, Attached are 5 patches related to celt_inner_prod() and dual_inner_prod() NEON intrinsics optimization. In 0004-Optimize-floating-point-celt_inner_prod-and-dual_inn.patch, the optimization changed the order of floating-point inner products, which will change the results. I created celt_inner_prod_neon_float_c_simulation() and dual_inner_prod_neon_float_c_simulation() to simulate the order floating-point operations in NEON optimization and compare their results. Sorry that I cannot bond the distance between original C function and NEON function to any giving reasonable small number or ratio. It's easy to c...

Thank Ulrich! Yes, using celt_assert(1.0 + celt_inner_prod_neon_float_c_simulation(x, y, N) == 1.0 + xy); celt_assert(1.0 + xy1_c == 1.0 + *xy1); celt_assert(1.0 + xy2_c == 1.0 + *xy2); can avoid the useage of VERY_SMALL. Hi Jean-Marc, I added { const opus_val32 xy_c = celt_inner_prod_neon_float_c_simulation(x, y, N); const int32_t *x_bi...
