<br>
I'm working on migrating a JIT compiler from the old ORCv1 JIT APIs to<br>
the newer ORCv2 ones and am having some trouble getting the code from<br>
chapter 1 of the "Building a JIT" [1] tutorial working properly. I<br>
have previously walked through the "My First Langauge" [2] tutorial<br>
and that went smoothly using the provided JIT class, but using the one<br>
from the JIT tutorial is giving me trouble.<br>
<br>
Kaleidoscope builds fine using Clang and LLVM version 9, but fails on<br>
an expression like this:<br>
<br>
ready> fun foo(c) c;<br>
Read function definition:<br>
define double @foo(double %c) {<br>
entry:<br>
ret double %c<br>
}<br>
<br>
kaleidoscope: kaleidoscope_baseline.cpp:980: void HandleDefinition():<br>
Assertion `add_q && "HandleDefinition: Error adding a module."'<br>
failed.<br>
Aborted<br>
<br>
I'm using the exact source code from the tutorials to reproduce the<br>
problem with some tiny changes to the front end to deal with some<br>
slight API changes introduced in the JIT tutorial where some functions<br>
return Expected. For example, the specific place that this is failing:<br>
<br>
FnIR->print(errs());<br>
fprintf(stderr, "\n");<br>
- TheJIT->addModule(std::move(TheModule));<br>
+ auto add_q = TheJIT->addModule(std::move(TheModule));<br>
+ assert(add_q && "HandleDefinition: Error adding a module.");<br>
InitializeModuleAndPassManager();<br>
<br>
<br>
I've looked at a previous thread discussing moving from ORCv1 to ORCv2<br>
[3] and watched the "Updating ORC JIT for Concurrency” talk by L.<br>
Hames & B. Loggins, but am still having a little trouble getting my<br>
head around everything without walking through a complete tutorial.<br>
I'd appreciate any guidance that you folks have on the migration as<br>
well as some help with this specific issue. I'm happy to share more<br>
about the source code and build settings if that is helpful.<br>
<br>
Thanks in advance,<br>
<br>
Zeke<br>
