<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">You might want to try calling the setMCPU() and setMArch() functions of EngineBuilder, and if that doesn’t work, look at what else lli is initializing in the
builder.<o:p></o:p></span></p>

two functions to have MCJIT work correctly.<o:p></o:p></span></p>
