<p class="MsoNormal">Hey Praveen,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your help! I still have questions and try providing some context.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For questions:<o:p></o:p></p>
<p class="MsoNormal">2.) I exactly mean that! Sadly I was not able to understand how to use the ‘define’ function, I tried that:<o:p></o:p></p>
<p class="MsoNormal"><img width="922" height="70" style="width:9.6041in;height:.7291in" id="Picture_x0020_1" src="cid:image001.png@01D52CCF.B4668E10"><o:p></o:p></p>
<p class="MsoNormal">I had no idea how to deal with that >o<<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">2.1.) With MCJIT I was actually used to getting the name of a function and then ‘answering’ with an address. Is that behavior not possible with OrcJIT anymore? I actually tried looking into the ‘setGenerator’ function of the JITDylib. As
a test I came up with this:<o:p></o:p></p>
<p class="MsoNormal"><img width="455" height="160" style="width:4.7395in;height:1.6666in" id="Picture_x0020_2" src="cid:image002.png@01D52CD0.5B8D6330"><o:p></o:p></p>
<p class="MsoNormal">This was pretty cool, because I actually saw the missing function ‘puts’ but I have no idea how to reply with an address for ‘puts’. Returning ‘Names’ actually makes the application pause and not go on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">4.) I used the code of Kaleidoscope JIT for my little experiments. If I understood it correctly, the JIT process is completed after I used the lookup function to find a symbol in the code. Now I would like to reset the instance of the Kaleidoscope
JIT I had, to jit new modules, which are not related to the previous modules I jitted.<o:p></o:p></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">Kind greetings<o:p></o:p></p>

<p class="MsoNormal">Hi Bjoern,<o:p></o:p></p>

<div>
<p class="MsoNormal">CC'ing Lang hames <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">For questions,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">1. In short yes, you can replace the memory manager, default one provided is section memory manager.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">2. If you mean by " address of already compiled code", yes you can do that.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> Like this<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> JITDylib.define(absoluteSymbols, ( Your_own_symbol , JITTargetAddress(Address of function))), now ORC can resolve all the references to Your_own_symbol to the provided the Address.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">3. Yes, all the class/function with legacy prefix will be removed in subsequent releases.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">4. Could please provide some more context on this? Like it's usage model, what goal you are aiming for?
<o:p></o:p></p>
