[LLVMdev] Problem about the type of Function's arguement in llvm
...function as follow:
for (Function::arg_iterator AI = F->arg_begin(); Idx != Args.size();
++AI, ++Idx) {
AI->setName(Args[Idx]);
// NamedValues is map<string, Value*>
NamedValues[Args[Idx]] = AI;
and when it try to get the value of arguement, it simply does:
Value *VariableExprAST::Codegen() {
Value *V = NamedValues[Name];
return V ? V : ErrorV("Unknown variable name");
}
It means that we can access value of arguement directly.
However, in llvm.org/demo and the chapter 6 of tutorial, it deals with
arguemnt:
1. allocate memory for arguement
2. then store the a...

Yes, it is possible to access the values (virtual registers) direclty,
but you may need to construct SSA form...
