...ntext of targeting the KNL, however, I'm a bit concerned about the addressing, and specifically, the size of the resulting encoding: > vmovdqu32 zmm0, zmmword ptr [rax + c+401280] ;load b[401280] in > zmm0 > > vpaddd zmm1, zmm1, zmmword ptr [rax + b+401344] > ; zmm1<-zmm1+b[401344] The KNL can only deliver 16 bytes per cycle from the icache to the decoder. Essentially all of the instructions in the loop, as we seem to generate it, have 10-byte encodings: 10: 62 f1 7e 48 6f 80 00 vmovdqu32 0x0(%rax),%zmm0 17: 00 00...
