Can haxe optimize SWF using link-report tech as flex compiler did?

[davy zhang]

In flex I can use -link-report to generate classes already used in parent swf, use generated link file to exclude these classes from the swf being loaded at compile time, by doing this can keep loaded swf smaller.

I don't know how to do this in haxe

Thanks!

OK, I find a way to exclude classes from compile using macro like --macro exclude('Main'), works fine.

But is there any way can compiler generate a used classes report file?

As long as you're not using heavily dynamic features (Lots of Reflect, Dynamic all over the place), the default dce (dead code elmination) will already be removing any of your classes that you don't use.

Thanks for your anwser, I understand dce's work, but I am trying to load some swf at run time so I can pre-exclude some class in loaded swf as it can using the parent swf's classes definitions at runtime.

I am digging the build macro stuff to see what can I do :D
