can you give an short (working) example code to show the different resulting

I used dmd.
i sometimes got the feeling that you underestimate the sheer power of
todays clang or gcc optimizers - so partly what gdc/ldc can do with your
reminds me of brian schotts exmaple of his sse2 optimized version of his
lexer - the dmd generated was much faster then the normal version, but
gdc/ldc results of the unoptimized versions are still 50% faster
i understand your focus on dmd - but talking about fast code and
optimizing WITHOUT even trying to compare with other compiler results is
just a little bit strange for someone who stated speed = money
