<br>
I am trying out ORC v2 and facing some problems.<br>
<br>
I am using LLVM 8.0.1.<br>
I updated my ORC v1 implementation from 6.0 to 8.0 based on<br>
Kaleidoscope example (i.e. using Legacy classes) and that works fine.<br>
<br>
Now I am trying out ORC v2 apis, based on<br>
<a href="https://github.com/llvm-mirror/llvm/blob/master/examples/Kaleidoscope/BuildingAJIT/Chapter2/KaleidoscopeJIT.h" rel="noreferrer" target="_blank">https://github.com/llvm-mirror/llvm/blob/master/examples/Kaleidoscope/BuildingAJIT/Chapter2/KaleidoscopeJIT.h</a>.<br>
<br>
I have got it to compile and build.<br>
But looks like my compiled code is not being optimized at all.<br>
<br>
For optimization I am using the PassManagerBuilder class to setup the<br>
passes. I use OptLevel = 2. This works perfectly with ORC v1 apis, but<br>
with ORC v2 I am not sure what is happening. I can see that the<br>
optimizeModule() is being called.<br>
<br>
Second issue is - I need to use an instance method as optimizeModule()<br>
but based on the example this is now a static method. Is this a<br>
restriction in the new api? I need to pass some parameters from the<br>
JIT context such as what optimization level to use.<br>
<br>
Thanks and Regards<br>
Dibyendu<br>
