<p class="MsoNormal">Hello LLVM-World,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">some days ago I asked how I can disable the emulated TLS support for the JIT Execution Engine. This worked and I got my undefined references to:<o:p></o:p></p>
<p class="MsoNormal">_Init_thread_epoch<o:p></o:p></p>
<p class="MsoNormal">_Init_thread_footer<o:p></o:p></p>
<p class="MsoNormal">_Init_thread_header<o:p></o:p></p>
<p class="MsoNormal">_tls_index<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I used the Linker to export those symbols, to resolve them for the JIT - but! My test code is crashing when I call the static constructors and destructors. The code is really simple and does work when I disable TLS.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Some background:<o:p></o:p></p>
<p class="MsoNormal">0.) I’m talking about this: https://docs.microsoft.com/en-gb/cpp/build/reference/zc-threadsafeinit-thread-safe-local-static-initialization?view=vs-2017<o:p></o:p></p>
<p class="MsoNormal">1.) I develop for Windows 7 x64 and use the LLVM 7 and Clang-CL<o:p></o:p></p>
<p class="MsoNormal">2.) The test code:<o:p></o:p></p>
<p class="MsoNormal">I have a global variable that awaits the address of a structure, this address is assigned via a lambda function that gets executed when calling the static constructors.<o:p></o:p></p>
<p class="MsoNormal">This lambda function has a static variable, instantiating a class - then it returns the address of this static instance.<o:p></o:p></p>
<p class="MsoNormal">3.) I don't use the Execution Engine to execute the static constructors - I took there address while the JIT process.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I can verify that I reach the lambda function when calling the static constructors, but the constructor of my class will never be called, because the application crashes before that.<o:p></o:p></p>
<p class="MsoNormal">Does anyone got TLS running on Windows? Am I overseeing something? I'm still a beginner (with annoying questions as I fear...)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Kind greetings and thank you for reading<o:p></o:p></p>
<p class="MsoNormal">Björn<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">@Lang: Sorry for pinging you... You seem to know so much about this area and Windows…<o:p></o:p></p>
