similar to: [LLVMdev] how to create default host TargetData?

It was the return type which was i64. I changed it also to my abi_int_size and it works now. I have to take care of a few other type translations, but it looks like MCJIT is working now. Thank you.

Something must be wrong with the Function Type. Try to debug into runFunction to see which if condition fails. Just a guess, if this is on 64 bit system the first argument type may be int64 but needs to be int32.

That makes it more mysterious then since I am indeed only calling a main function. Perhaps I have to invoke it a different way. Here's my call I have now: auto main = linker->getModule()->getFunction( "main" ); std::vector<llvm::GenericValue> args(2); args[0].IntVal = llvm::APInt( platform::abi_int_size, 0 ); args[1].PointerVal = nullptr; llvm::GenericValue gv =

When building multiple modules should I be using multiple LLVMContext's or just one of them shared between the modules? I'm a little bit uncertain in regards to how the types work. The IR type checking appears to check exact ptrs for equality so how would multiple contexts actually work? Or is the type checking limited to within a given module? -- edA-qa mort-ora-y -- -- -- -- -- -- --

MCJIT::runFunction supports only main-style argument passing but not other cases like the JIT. These types of arguments will work: (int, char**, char**) (int, char**) (int) (void) The general case is not supported since it requires creating a small stub function, compiling and running it on the fly, supported by JIT but not MCJIT. However, with the supported calling sequences, you can probably

I don't want to do just a visual compare, i would like to manipulate, iterate, over the "old" version of the function.

I added several more clauses to see the result. It looks like the landing pad information is generated correctly: I get the correct number of action records, each record has a reasonable index into the type table (from 1 to 9). The encoded address increment in 4 however, which is unexpected since they are size 8 (in the JIT they increment by 8). Whatever is causing that may also be responsible for

But the incoming value from the landing pad will always be null, won't it? If so, just iterate through the predecessors and add the terminator as the incoming value if it's an invoke instruction and add the null value it's not. Won't that work?

I know the size must be known since alloca and getelementptr both implicitly use it, but I don't see any way to get access to the size directly. I know my final compiler will have to get the size itself, but I'm just doing some simple tests directly in assembly now and am hoping there is an easy way to get the size of a

Hi, LLVMContext was designed to support multithreading by holding the compilation context for each thread in a separate LLVMContext. If you're building modules in parallel you definitely need one LLVMContext per thread. If you're talking about compiling multiple modules sequentially with a single context I believe that should work, though I don't know how well tested it is. I think

Super, that clarifies a lot what happens.  And yes, it's been a challenge calling C APIs with by-value structures, but I think I've got it working now, at least on x86_64 Linux. If I understood correctly, when llvm sees a struct like `foo = { i8, i64, float }` and then a function like `bar( %foo )` it is the same as the function `bar( i8, i64, float )`?  Is the call guaranteed to be byte

What I would like to do is, during the I do a dump of the Module (Module.print) before and after running it through a PassManager (you could also use the Function.print method I think). You can put just a single pass in the PassManager to
