<p class="MsoNormal">Heyho both Mailinglists,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'm not sure if I encountered a bug or if I'm doing something wrong. I compiled a "Hello World"-function with Clang to LLVM-IR code, while passing the "-mretpoline" flag.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I tried jitting and calling that function with the KaleidoscopeJIT code, but when calling "lookup" for that function the application crashed.<o:p></o:p></p>
<p class="MsoNormal">I also tried that file in an old MCJIT implementation I had - there the application crashed when calling the function (but it does find the address for the function first).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If I recompile my code without the "-mretpoline" flag, everything works fine again.<o:p></o:p></p>
<p class="MsoNormal">I compiled Clang and the LLVM files from the LLVM8 source files, I run them under Windows7 64bit. Any ideas what might went wrong?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
