IRBuilder constraints
...t;>& irb;
llvm::Value* op1 = llvm::ConstantInt::getSigned(irb.getInt32Ty(),
constVal);
auto* pt = llvm::PointerType::get(op1->getType(), 0);
auto* addr = irb.CreateIntToPtr(op1, pt);
auto* loaded = irb.CreateLoad(addr);
irb.CreateStore(loaded, module->getNamedGlobal(regname));
I cannot get LLVM to leave an llvm::Value as ConstantInt in every case, if
I pass it to IRBuilder for processing(for example through a globalvariable
storing instruction).
Do you know how I can tell IRBuilder, or any other part of LLVM, to leave a
supplied or retrieved llvm::Value as const?
