Hello,

I need help in passing global string variable to runtime. This is how I have created a global variable and passed to the runtime -

\`\`\`

Constant \*fname = ConstantDataArray::getString(M->getContext(),"hi", true);

Value \*FBloc = new GlobalVariable(\*M, fname->getType(), true, GlobalValue::InternalLinkage, fname, "fBloc");

FBloc->getType()->dump();

BitCastInst\* BCToAddr = new BitCastInst(FBloc, PointerType::getUnqual(Type::getInt8Ty(M->getContext())),"", First);

FuncInit = M->getOrInsertFunction("funcInit", VoidTy, PtrVoidTy);

IRB.CreateCall(FuncInit, {BCToAddr});\`\`\`

Unfortunately, runtime gets null pointer

\`\`\`

extern "C" void funcInit(void \*fName){

std::cout<<"\*\*\*\*\*\*funcInit\*\*\*\*\*"<<(char \*)fName;

Breakpoint 1, funcInit (fName=0x0) at handleReal.cpp:66

66 extern "C" void funcInit(void \*fName){

(gdb)

\`\`\`
