Can the TLS directory be avoided? (compiling on windows)
I mean, can it avoided without losing GC and main language 
features?

I found out that also when with -vtls there is no output, there 
is TLS Directory in the final binary.

Wait, why on earth do you not want TLS?

Compatibility issues (like under XP)

Solutions like this is not enough stable:
https://github.com/dlang/druntime/blob/master/src/core/sys/windows/dll.d

I'm searching for solution like the /Zc:threadSafeInit- flag 
under VS2015

D does not support Windows XP.
If you absolutely require it, you will have to contact Walter about support.

Let me care about it ;)
I just need help with the TLS :)

Mark your variables with __gshared. I would say shred, but it has 
some restrictions to it, where __gshared is the equivalent to 
global variables in C.

immutable variables are also not put in TLS.

Thank you for yours replys but there is a tls directory even when 
I compile empty main..

It's very likely that there are TLS variables in druntime that are 
linked in. You can identify them by looking at the map file.

I don't know what you mean by the TLS directory, can you explain?

You could probably modify druntime so that it doesn't use any 
Thread-Local Storage, but Phobos uses it extensively, as global 
and static variables are put in TLS by default since D 2.030:

https://dlang.org/migrate-to-shared.html

Are you against emulated TLS also?  If not, I have modified dmd, 
ldc, and druntime to use the same emulated TLS scheme Walter came 
up with for OS X, for my Android port:

https://github.com/dlang/dmd/pull/3643
https://github.com/ldc-developers/ldc/pull/1447
https://github.com/dlang/druntime/pull/784

You may be able to use something similar on Windows, depending on 
how feasible such an emulated TLS scheme is there and if you want 
to dig into these details.
