Gf2p8affineqb
WebIf you compile using GCC, set -O3 -march=native to make sure vectorisation is performed using whichever SIMD instruction set (SSE, AVX, ...) the CPU you are compiling on supports, and add -fopt-info to make the compiler verbose about optimisations: g++ -O3 -march=native -fopt-info -o main.o main.cpp. This will give you output like: Webx86 and amd64 instruction reference.
