Member Function Documentation

collectVarUses()

virtual void AST::Statement::collectVarUses ( std::unordered_set< std::string > &  decls, std::unordered_set< std::string > &  uses  )

pure virtual

Recursively visit all of the children of this statement, collecting variables that are declared and used in it.

This is used to allocate space for all declared variables and to bind variables to closures.

Implemented in AST::ClassDecl, AST::WhileLoop, AST::IfStatement, AST::Return, AST::Decl, AST::Call, AST::Assignment, AST::VarRef, AST::BinOpBase, AST::StringLiteral, and AST::Number.

compile()

virtual void AST::Statement::compile ( Compiler::Context &  c )

inlinevirtual

Compile this statement to LLVM IR.

Reimplemented in AST::WhileLoop, AST::IfStatement, AST::Return, AST::Decl, AST::Assignment, and AST::Expression.

Definition at line 37 of file ast.hh.

interpret()

virtual void AST::Statement::interpret ( Interpreter::Context &  c )

pure virtual

Execute this statement in the interpreter.

Implemented in AST::ClassDecl, AST::WhileLoop, AST::IfStatement, AST::Return, AST::Decl, AST::Assignment, and AST::Expression.
