I expected that you defined a make target similar to linux-x86-64-avx, which has -DJOHN_AVX in the right place. > It compiles a running binary, but I had to comment out xgetbv in x86-64.S as I was getting this error: > > no such instruction: `xgetbv' Oh, I thought that any assembler capable of AVX instructions would also recognize this one, which is closely related. What does "as --version" say? In fact, I thought that the reason why you were not able to build with AVX before was old version of binutils (specifically, as) - but this is not affected by you moving from gcc to icc, is it? Since your build succeeded now, I think you'd be able to build with gcc as well. > Here are some benchmarks, It looks like you got lucky in terms of DES_bs_all alignment. The program could as well segfault. Can you try an OpenMP build? With those, DES_bs.[ch] actually ensure proper alignment in a way that is not gcc-specific. > Benchmarking: Traditional DES [128/128 BS AVX-16]...
