<p dir="ltr">I don't have another hardware ARM system, but I got it working under a qemu ARM system before trying Android and there are no issues there. I'm only putting one module in the JIT, so that shouldn't be the issue; thanks for the registerEHFrame suggestion though. I won't get time to try it until the weekend though.</p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">It might be useful to set breakpoints in the memory manager you are using. During finalizeObject you are likely to see calls to finalizeMemory, getSymbolAddress,
registerEHFrames and notifyObjectLoaded. I think registerEHFrames is the most likely source of the problem, particularly given that the debugger is also crashing. If that’s the problem, you could probably get a little further (for experimental purposes at
least) by just having the memory manager do nothing in response to that call.<u></u><u></u></span></p>

<p class="MsoNormal">I'm trying to build LLVM on Android rather than the other way around! Really just to see if it can be done. I worked out the first problem (my code was written for the old JIT and I'd missed something in updating to the MCJIT to make it
work on ARM). It still doesn't work, but at this point I have no idea why and it'll be a while before I get to look at it again: the Android debug tools simply crash and give no output whatsoever, so all I know is that the test app exits somewhere inside MCJIT::finalizeObject.<br>
