Definition at line 622 of file expr.h.

static bool AddressOfExpr::classof ( ASTNode const *  N)
inlinestatic

Definition at line 623 of file expr.h.

References ASTNode::AddressOfExprID, and ASTNode::getValueID().

int AddressOfExpr::EstimateCost ( ) const
virtual

Estimate the execution cost of the node (not including the cost of the children. The value returned should be based on the COST_* enumerant values defined in ispc.h.

Implements ASTNode.

Definition at line 7818 of file expr.cpp.

Symbol * AddressOfExpr::GetBaseSymbol ( ) const
virtual

For expressions that have values based on a symbol (e.g. regular symbol references, array indexing, etc.), this returns a pointer to that symbol.

Reimplemented from Expr.

Definition at line 7773 of file expr.cpp.

References expr, and Expr::GetBaseSymbol().

llvm::Constant * AddressOfExpr::GetConstant ( const Type type) const
virtual

If this is a constant expression that can be converted to a constant of the given type, this method should return the corresponding llvm::Constant value. Otherwise it should return NULL.

Reimplemented from Expr.

Definition at line 7824 of file expr.cpp.

References AssertPos, Module::errorCount, expr, PointerType::GetBaseType(), Expr::GetConstant(), Expr::GetType(), lConvertPointerConstant(), and m.

const Type * AddressOfExpr::GetLValueType ( ) const
virtual

Returns the type of the value returned by GetLValueType(); this should be a pointer type of some sort (uniform or varying).

Reimplemented from Expr.

Definition at line 7760 of file expr.cpp.

References expr, Expr::GetType(), and PointerType::GetUniform().

const Type * AddressOfExpr::GetType ( ) const
virtual

Returns the Type of the expression.

Implements Expr.

Definition at line 7737 of file expr.cpp.

References AssertPos, Module::errorCount, expr, Expr::GetLValueType(), Type::GetReferenceTarget(), Expr::GetType(), PointerType::GetUniform(), and m.

llvm::Value * AddressOfExpr::GetValue ( FunctionEmitContext ctx) const
virtual

This is the main method for Expr implementations to implement. It should call methods in the FunctionEmitContext to emit LLVM IR instructions to the current basic block in order to generate an llvm::Value that represents the expression's value.

Implements Expr.

Definition at line 7722 of file expr.cpp.

References expr, Expr::GetLValue(), Expr::GetType(), Expr::GetValue(), and FunctionEmitContext::SetDebugPos().

Expr * AddressOfExpr::Optimize ( )
virtual

This method should perform early optimizations of the expression (constant folding, etc.) and return a pointer to the resulting expression. If an error is encountered during optimization, NULL should be returned.

Implements Expr.

Definition at line 7812 of file expr.cpp.

void AddressOfExpr::Print ( ) const
virtual

Prints the expression to standard output (used for debugging).

Implements Expr.

Definition at line 7779 of file expr.cpp.

References expr, Expr::Print(), and SourcePos::Print().

Expr * AddressOfExpr::TypeCheck ( )
virtual

This method should perform type checking of the expression and return a pointer to the resulting expression. If an error is encountered, NULL should be returned.

Implements Expr.

Definition at line 7791 of file expr.cpp.

References AssertPos, Error(), Module::errorCount, expr, Expr::GetLValueType(), Expr::GetType(), m, and ASTNode::pos.
