Presumably you mean pmaddubsw, but isn't it a problem that the weights can go from 0 to 128 inclusive? That is, if one weight is 0, the other is 128, which means it doesn't actually fit in seven bits. So unless I am missing something, pmaddubsw can't be used without a test for 0. > But the patches need a lot more testing on different hardware. Running the test suite on ppc64, ARM, x86-64 with various implementations disabled revealed no problems for me.
