Hi Jean-Marc, I attached the new version in inner_prod_5patches_v2.zip which synced to the current master. For fixed-point ARM, only 0003-Optimize-fixed-point-celt _inner_prod-and-dual_inner_.patch changes the performance. For floating-point ARM, only 0004-Optimize-floating-point-c elt_inner_prod-and-dual_inn.patch changes the performance. Patch 1 and 2 are code clean-up and can only affect x86 performance. Patch 5 has neglectable effect on floating-point ARM performance. Thanks, Linfe...

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_simulatio...
