hi, please help with this, can we reduce the footprint?

thanks!


OK, I just put on another git repo, which is the simpley 
helloworld in D, and it

generates 849KB for print a single line!

https://github.com/dangbinghoo/hello_world_d

so, maybe there's something wrong with D compiling?


thanks!


OK, talked in Discord.

answer is clear: 1. D runtime is about 400KB on amd64 stripped. 
2. phobos is set of big templates, writeln is expensive.

betterC print a helloworld only costs 6.3KB stripped.




thanks!

hi,

I just asked for help about this before, on that time, my 
solution is to remove whatever dub dependencies which are 
optional.


now, I'm re-examining the dlang program footprint size, and I 
put a github example repo here:


https://github.com/dangbinghoo/dlang_footprint_test.git

the example is simply a json ser/deser test depends on ASDF, on 
my machine it generates a binary about 914K using LDC2.


Note: as I'm focused on embedded system development, what I 
want help with is only for the situation using LDC compiler.


thanks!
