...function object with external linkage and the specified function type llvm::Function* pFuncObj = llvm::Function::Create( pFuncType, llvm::Function::ExternalLinkage, name, s_pModule ); // Add a global mapping in the execution engine for the function pointer s_pExecEngine->addGlobalMapping(pFuncObj, pFuncPtr); Where pFuncPtr is a void pointer to the native C++ function. I register several of these native functions which are meant to be runtime support for the scripts I then JIT compile. After compiling each script, I run optimization passes. If the global DCE o...

For example: $ cat gdce.ll define i32 @foo() {

If I try to call the getReturnType() method on the function object b...
