M$ C on Win32 (X86/32), using Visual Studio.
declspec(thread) int ithread;
ithread = 1;
mov eax, dword ptr [__tls_index (417328h) ]
mov ecx, dword ptr fs:[2Ch]
mov edx, dword ptr [ecx,+eax*4]
mov dword pth[edx+104h],1
This is essentially the same code as with Delphi. Supposedly as with
Delphi [__tls_index (417328h) ] is always 0 with normal applications.
(no idea what this is useful for)
