aeubanks added inline comments.
================
Comment at: llvm/lib/AsmParser/LLParser.cpp:1463
+ // RAUW it later with a global/function of the correct type.
+ Type *ElemTy = PTy->isOpaque() ? Type::getInt8Ty(M->getContext())
+ : PTy->getElementType();
----------------
With --force-opaque-pointers, we never get to `Function::Create()`. Can we always create a GlobalVariable (or always create a Function) and RAUW with the proper GlobalVariable/Function later?
================
Comment at: llvm/lib/IR/AsmWriter.cpp:188
- bool GetsReversed =
- !isa<GlobalVariable>(V) && !isa<Function>(V) && !isa<BasicBlock>(V);
+ bool GetsReversed = !isa<BasicBlock>(V);
if (auto *BA = dyn_cast<BlockAddress>(V))
----------------
could you explain this change?
