Welcome to part 4 of the "Implementing a language with +LLVM" tutorial.

+ + +
Code Generation setup
+ + +
+ +

+In order to generate LLVM IR, we want some simple setup to get started. First, +we define virtual codegen methods in each AST class:

+ +
+
+/// ExprAST - Base class for all expression nodes.
+class ExprAST {
+public:
+  virtual ~ExprAST() {}
+  virtual Value *Codegen() = 0;
+};
+
+/// NumberExprAST - Expression class for numeric literals like "1.0".
+class NumberExprAST : public ExprAST {
+  double Val;
+public:
+  explicit NumberExprAST(double val) : Val(val) {}
+  virtual Value *Codegen();
+};
+...
