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 Modifiable checkModifiable(Scope* sc, int flag)
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.
checkOverridenDtor void checkOverridenDtor(Scope* sc, FuncDeclaration f, bool function(DtorDeclaration) check, string checkName): Checks whether f is a generated DtorDeclaration that hides a user-defined one which passes check while f doesn't (e.g. when the user defined dtor is pure but the generated dtor is not). In that case the method will identify and print all members causing the attribute missmatch.
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): 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.
resolveLoc Expression resolveLoc(Loc loc, Scope* sc): Resolve __FILE__, __LINE__, __MODULE__, __FUNCTION__, __PRETTY_FUNCTION__, __FILE_FULL_PATH__ to loc.
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.

Static functions

combine Expression combine(Expression e1, Expression e2): Combine e1 and e2 by CommaExp if both are not NULL.
deinitialize void deinitialize(): Deinitializes the global state of the compiler.
extractLast Expression extractLast(Expression e, Expression e0): If 'e' is a tree of commas, returns the rightmost expression by stripping off it from the tree. The remained part of the tree is returned via e0. Otherwise 'e' is directly returned and e0 is set to NULL.
