Hi I hope this is a proper place to put my question. I've compiled Kaleidoscope from "Adding JIT and Optimizer Support" tutorial. Basically it works just fine but when I try to run extern'ed putchard function it aborts. Please, tell me what am I doing wrong? Here is more information: My PC runs FreeBSD. I've copied the toy source code exactly and didn't change it. Here is the log: # ./toy ready> extern putchard(x); ready> Read extern: declare double @putchard(double) ready>...

Please make sure you're using C linkage for such functions, due to mangling the name of function being emitted is not "putchard". Something like this: extern "C" void putchard(char c) { ... } Or...

To make it work, you have to use "extern "C" __declspec(dllexport) double putchard(double X)" so the function will be found via GetProcAddress for the main module. This wouldn't hurt for Linu...

Hi, I'm following the Kaleidoscope tutorial (which is very good btw) and am having difficulties having function calls for functions that haven't been defined getting resolved to plain C++ functions. In the tutorial (end of chapter 4), executing "extern putchard(x); putchard(120);" should execute the corresponding C++ function defined in the same file. Unfortunately in my case it only produces the following error: ready> ERROR: Program used external function 'putchard' which could not be resolved! Any idea of what could be wrong? Thanks!...

To try to find out why it was crashing, I followed the trail of function calls: C:\llvm\examples\Kaleidoscope\Orc\initial\toy.cpp auto ExprSymbol = J.findUnmangledSymbol("__anon_expr"); JITSymbol findUnmangledSymbol(const std::string Name) { return findSymbol(mangle(Name)); } JITSymbol findSymbol(const std::string &Name) { return CompileLayer.findSymbol(Name,

Addendum: this still fails: auto ExprSymbol = J.findSymbol("putchard"); As yet, I have no idea why - that symbol even seemed to be exported: extern "C" double putchard(double X) { putchar((char)X); return 0; } On Fri, Apr 1, 2016 at 2:42 AM, Russell Wallace <russell.wallace at gmail.com> wrote: > To try to find out why it was crashi...
