How I can do auto-vectorization and loopunroling?

There is only -vectorize-slp but no -vectorize.

With
-O3 -release -disable-boundscheck -mcpu=native -vectorize-slp -mattr=avx
flags ldc2 produce code without AVX.

Isn't -vectorize implicit in -O3 (Perhaps even in -O2)?

Hi Ilya,

your command line looks ok. I think there is a bug in the command line arguments.
I try to fix it now.

Is fixed in the merge-2.064 branch and will be in next alpha release.

Hi bearophile,

thanks for the example. I saw your other post, too. I am still a bit slow - there is a backlog caused by FOSDEM talk.
