Someone knows how to strip unused symbols on final binary using ldc on windows ?
i found this about this topic:

https://forum.dlang.org/post/yvmnkvzgoxhcfavjayky@forum.dlang.org

that uses --gc-sections and --version-script but this options are not avaliable in windows lld-link

That was about ELF symbol visibility and doesn't apply to Windows at all. - The symbols are stripped by default for Windows targets (/OPT:REF for MS linker/LLD). You can cross-check by disabling via `-disable-linker-strip-dead`.

Hmm, ok, my question is in fact relate to this kind of thing:
https://godbolt.org/z/NGjyyx

Why int example.add(int, int): its still on the binary when all u need is alredy optimized to
main:
 mov     eax, 30
 ret

?

You're inspecting an object file, before any linker and symbol stripping is involved.

Oh, i thought that the symbol stripping was before linker!, my bad, thanks!
