Expression

addDtorHook Expression addDtorHook(Scope* sc): Destructors are attached to VarDeclarations. Hence, if expression returns a temp that needs a destructor, make sure and create a VarDeclaration for that temp.
addressOf Expression addressOf(): Take address of expression.
checkModifiable int checkModifiable(Scope* sc, int flag = 0): Parameters: sc: scope flag: 1: do not issue error message for invalid modification
checkNogc bool checkNogc(Scope* sc, FuncDeclaration f): Calling function f. Check the @nogc-ness, i.e. if we're in a @nogc function we can only call other @nogc functions. Returns true if error occurs.
checkPostblit bool checkPostblit(Scope* sc, Type t): Check that the postblit is callable if t is an array of structs. Returns true if error happens.
checkPurity bool checkPurity(Scope* sc, FuncDeclaration f): Calling function f. Check the purity, i.e. if we're in a pure function we can only call other pure functions. Returns true if error occurs.
checkPurity bool checkPurity(Scope* sc, VarDeclaration v): Accessing variable v. Check for purity and safety violations. Returns true if error occurs.
checkReadModifyWrite bool checkReadModifyWrite(TOK rmwOp, Expression ex = null): Check whether the expression allows RMW operations, error with rmw operator diagnostic if not. ex is the RHS expression, or NULL if ++/-- is used (for diagnostics) Returns true if error occurs.
checkSafety bool checkSafety(Scope* sc, FuncDeclaration f): Calling function f. Check the safety, i.e. if we're in a @safe function we can only call @safe or @trusted functions. Returns true if error occurs.
checkType bool checkType(): Check that the expression has a valid type. If not, generates an error "... has no type".
checkValue bool checkValue(): Check that the expression has a valid value. If not, generates an error "... has no value".
copy Expression copy(): Does *not* do a deep copy.
deref Expression deref(): If this is a reference, dereference it.
isBool bool isBool(bool result): Does this expression statically evaluate to a boolean 'result' (true or false)?
isLvalue bool isLvalue(): Return !=0 if expression is an lvalue.
printAST void printAST(int indent = 0): Print AST data structure in a nice format.
resolveLoc Expression resolveLoc(Loc loc, Scope* sc): Resolve __FILE__, __LINE__, __MODULE__, __FUNCTION__, __PRETTY_FUNCTION__ to loc.
semantic Expression semantic(Scope* sc): Semantically analyze Expression. Determine types, fold constants, etc.
toBoolean Expression toBoolean(Scope* sc): If expression can be tested for true or false, returns the modified expression. Otherwise returns ErrorExp.
toLvalue Expression toLvalue(Scope* sc, Expression e): Give error if we're not an lvalue. If we can, convert expression to be an lvalue.
trySemantic Expression trySemantic(Scope* sc): Try to run semantic routines. If they fail, return NULL.

Static functions

combine Expression combine(Expression e1, Expression e2): Combine e1 and e2 by CommaExp if both are not NULL.
extractLast Expression extractLast(Expression e, Expression* pe0): If 'e' is a tree of commas, returns the leftmost expression by stripping off it from the tree. The remained part of the tree is returned via *pe0. Otherwise 'e' is directly returned and *pe0 is set to NULL.
