How should I compile my program to enable array vectorization?

I have tried dmd -march=native, -march=avx2 as changlog suggest 
but does not work

I have tried even just -march=native or -march=avx2 but still 
does not compile

Error: unrecognized switch '-march=avx2'

Error: unrecognized switch '-march=native'
