I believe the correct way is actually include the Interpreter’s header and the rest is handled automatically.

Oops, missed initializing some stuff. Added: LLVMLinkInMCJIT(); LLVMInitializeNativeTarget(); LLVMInitializeNativeAsmPrinter(); LLVMInitializeNativeAsmParser(); Now it crashes in LLVMGetFunctionAddress(). Hmm.

I'm trying to wire up some code to use the MC-based JIT; my understanding is that it should be able to JIT AVX code (and that the regular JIT cannot). However, I'm getting the error "Target does not support MC emission!" when I call EngineBuilder::create(). I assume that I'm just not doing something necessary for initialization, but I'm not sure what it would be--I am

Ok. I can make a copy of the unique_ptr before moving it into the builder's constructor and use the copy later on. It is confusing to require a unique_ptr.

Hi Ralf, FYI, old JIT doesn't support AVX at all, no encoding info, etc... The only way to use AVX+JIT is using MCJIT, which contains the correct encoding, but unfortunately the framework isn't good yet as the old one is.

Hi Matt, I am unsure about MCJIT, but I guess the problem is the same. Just like when invoking llc, you need to pass the information to use AVX (llc -mattr=+avx). I guess the corresponding code should look like this: llvm::EngineBuilder engineBuilder(module); engineBuilder.setErrorStr(&eeError); engineBuilder.setEngineKind(llvm::EngineKind::JIT);

Following along from lli code, if you add a call to InitializeNativeTargetAsmPrinter() during setup, it gets a bit farther and crashes rather than issuing that error. (Rebuilding with debugging symbols now to dig into it further…) -matt Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000 0x000000010000349e in

Ah, now that makes sense. Guess I was a little over-eager with my bugreport. Thanks! :) However, I am now running into the same Problem as Matt ("Target does not support MC emission!").

I've been following this guide: http://llvm.org/docs/tutorial/LangImpl4.html and am getting an error when trying to create an execution engine. When running this code: executionEngine = llvm::EngineBuilder(module).setErrorStr(&errStr).create(); errStr contains: "Interpreter has not been linked in." I'm using this command to build: g++ -g errors.o lexer.o parser.o lang.o

When using ORC JIT, I'm having trouble with external function resolution (that is, of a function defined in the app, with C linkage). I add a declaration for the function to my IR, and when I use MCJIT, it finds it and all is well, But when I use ORC JIT (I *think* correctly, at least it closely matches what I see in the tutorial), I get an LLVM error, "Program used external function

Hi all, Writing my own LLVM client I've noticed a potential null pointer dereference in EngineBuilder::selectTarget. The class has an optional pointer to the ErrorStr, which can be initialzied through setErrorStr() method. Although, it's strictly optional, selectTarget doesn't verify its value before assignment. Please find patch for branch release_31, revision 155051 attached. -

Thanks so much! This seems to do the trick. I would have spun my wheels for a long time before discovering all of this, wow.

Hi Yury, No need for the "{" "}" since it's a single statement in the compound statement. Other than that minor style detail, this looks fine assuming it applies cleanly to trunk.

Thank you for your response Jim. As of revision 153342 it applies properly to trunk. No, unfortunately I don't have access, would you please commit it for me?

No worries. :) I'll try to keep this in mind and make sure I address it in future Kaleidoscope tutorial chapters - these issues tripped me up the first time I encountered them too.

Hi Matt, hi Bruno, I am still struggling to use AVX via MCJIT on TOT... did you succeed yet? I seem to be unable to even get lli to run some code with the "use-mcjit" flag. I attached a test case that works fine for "lli y.bc" but exits with an error for "lli -use-mcjit y.bc": "LLVM ERROR: Unknown object format" If I call InitializeAllTargetMCs() before
