Hi:
I’m building a small tool on top of LLVM Core Library.
LLVMContext context;
SMDiagnostic diag;
Module *M = parseIRFile(InputIR, diag, context).get();
if (M == nullptr) {
diag.print("LLVM", errs());
exit(-1);
}
assert(M->isMaterialized() && "Module not materialized!");
PointerType *ArrayPtrTy =
M->getTypeByName("struct._Array")->getPointerTo();
However this piece of code crashes at Module::getTypeByName because getContext().pImpl is NULL pointer. Other similar issues include Module::getTypeByName results in a NULL pointer dereference because TheTable in StringMap is not allocated/initialized.
It would be great if someone could show me what’s the correct way to initialize all this kind of internal data structures so I could focus on my tool’s logic
