Hello, I'm using the llvm-c bindings for C, but I'm getting some problems, the LLVMCreateExecutionEngine is returning 1 but the error message is an empty string (it's !=NULL). The steps I'm doing is to create the module, then I call LLVMVerifyModule to verify and it works fine, later I call LLVMCreateModuleProviderForExistingModule and it returns !=NULL MP, so it's ok, but then when I call something like this: error_ret = LLVMCreateJITCompiler(&engine, provider, 0, &verror) It returns 1 in error_ret and an empty string in verror, d...

...d I would really welcome as much advice as you can give me on that but it works. The issue comes when I actually create 2 different modules. One being a "standard" library of sorts and the other the main module which should use it. I create both modules, with no errors appearing if I use LLVMVerifyModule() on them. The problem is how do I link them? I tried to do it like this: // if an error occurs LLVMLinkModules() returns true if (true == LLVMLinkModules(main_module, stdlib_module, LLVMLinkerDestroySource, &error)) { bllvm_error("Could not link L...

Or do you mean I need to load the module into memory before calling LLVMGetBitcodeModuleInContext2? > Yes, you need to load the module into memory first. > LLVMCreateMemoryBufferWithContentsOfFile will do that for you.

...with fatal error handling. Is anybody aware of a program that uses LLVM as > a library, produces IR in memory, runs the verifier, and does not simply > abort if the verifier fails in non-development builds? > I'm doing the same as clang: #ifndef NDEBUG char *error = nullptr; LLVMVerifyModule(g->module, LLVMAbortProcessAction, &error); #endif However the LLVM API is defined such that trying to call codegen functions on an invalid module is undefined, and aborting in this case makes sense. This is really just a more sophisticated assert(). I'm a fan of assert(); I like havin...

...llvm 3.9.0. I found this while troubleshooting what I now to believe to be a separate issue in my frontend code that caused LLVM to go into an infinite loop writing into a .o file. When I ran that IR code against llc, I got "error: initializer with struct type has wrong # elements" which LLVMVerifyModule did not catch. I can provide this example IR as well if wanted.
