...ne value only, the result of: Value *ThenV = Then->Codegen(); (...) Value *ElseV = Else->Codegen(); (...) PN->addIncoming(ThenV, ThenBB); PN->addIncoming(ElseV, ElseBB); But both Then and Else are expressions, so the Value returned is in the form of a single variable. ExprAST *Then = ParseExpression(); (...) ExprAST *Else = ParseExpression(); In my toy language, I accept any number of statements inside a block. Ignoring nested if statements, should I keep track of *each* variable mutation inside the block, or is there some LLVM magic (as I'm getting used to)? A simple C example would...
