static bool ReferenceExpr::classof ( ASTNode const *  N)

Definition at line 541 of file expr.h.

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

int ReferenceExpr::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 7497 of file expr.cpp.

Symbol * ReferenceExpr::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 7449 of file expr.cpp.

References expr, and Expr::GetBaseSymbol().

const Type * ReferenceExpr::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 7468 of file expr.cpp.

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

const Type * ReferenceExpr::GetType ( ) const
virtual

Returns the Type of the expression.

Implements Expr.

Definition at line 7455 of file expr.cpp.

References expr, and Expr::GetType().

Referenced by Print().

llvm::Value * ReferenceExpr::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 7415 of file expr.cpp.

References FunctionEmitContext::AllocaInst(), AssertPos, Globals::ctx, Module::errorCount, expr, g, Expr::GetLValue(), Expr::GetType(), Expr::GetValue(), Type::LLVMType(), m, FunctionEmitContext::SetDebugPos(), and FunctionEmitContext::StoreInst().

Expr * ReferenceExpr::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 7481 of file expr.cpp.

References expr.

void ReferenceExpr::Print ( ) const
virtual

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

Implements Expr.

Definition at line 7503 of file expr.cpp.

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

Expr * ReferenceExpr::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.
