Taking one step back, I'm not clear I'm even setting the triple/DataLayout on the module correctly:     module = new llvm::Module( "test", *llvm_context );     module->setTargetTriple( platform::target->triple ); Is that enough to create an appropriate DataLayout for the module?  I don't see anyway to convert a triple to a DataLayout, so I can't call `setDataLayout`.

I don't know if I'm setting the triple of my execution engine correctly.  This is leading to an issue where a struct `{i8,i64}` is not getting the same layout as the ABI expects. I setup my engine/module like this:      llvm::SmallVector<std::string,2> mattrs;      llvm::EngineBuilder builder{ unique_ptr<llvm::Module>(module) };      llvm::ExecutionEngine * ee = builder.    

Hi, Could you share how you compile IR and which version of JIT you use (Orc, MCJIT)? Could it be that you are using interpreter instead of actual JIT? Cheers, Alex. > On 5.

I'm having issues of my compiler, and JIT execution, of LLVM IR being rather slow. It's accounting for the vast majority of my full compilation time.  I'm trying to figure out why this is happening, since it's becoming an impediment.  (Note: by slow I mean about 3s of time for only about 2K of my front-end code, 65K lines of LLVM-IR) Using valgrind I see some functions which seem

What exactly is your alignment settings in your LLVM struct? Something like this would tell you the alignment of "something". const llvm::DataLayout dl(theModule); size_t size = dl.getPrefTypeAlignment(something); IIn "my" compiler, I don't do anything special to align structs, so it's plausibly your specific data-layout that says that i64 only needs aligning to

I think I see a potential issue. My ExecutionEngine setup may not be using the same target as my object code emitting, and in this test case I'm running in the ExecutionEngine.  I'll go over this code to ensure I'm creating the same triple and see if that helps -- I'm assuming it will, since I can't imagine the exact same triple with clang would produce a different layout.
