--- Comment #3 from Martin Nowak ---
For example this is the sequence to write to a TLS variable in X86 code
(non-PIC), the one for X64 doesn't work, because dmd's IASM doesn't support RIP
relative addressing.
size_t a;
void main()
{
asm
{
mov EAX, GS:[0x00];
mov ECX, a;
mov [EAX+1*ECX], 3;
}
}

[Issue 13938] IASM shouldn't be able to access TLS variables
https://issues.dlang.org/show_bug.cgi?id=13938 --- Comment #2 from Martin Nowak --- It's fairly tricky, we would need to ensure that the correct code sequence is used. That's not really trackable and many can't be correctly written in D's IASM. So indeed it would be better to disallow them. --
