EstimateCost()

int SyncExpr::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 8051 of file expr.cpp.

References COST_SYNC.

GetType()

const Type * SyncExpr::GetType ( ) const

virtual

Returns the Type of the expression.

Implements Expr.

Definition at line 8043 of file expr.cpp.

References AtomicType::Void.

GetValue()

llvm::Value * SyncExpr::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 8045 of file expr.cpp.

References FunctionEmitContext::SetDebugPos(), and FunctionEmitContext::SyncInst().

Optimize()

Expr * SyncExpr::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 8060 of file expr.cpp.

Print()

void SyncExpr::Print ( ) const

virtual

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

Implements Expr.

Definition at line 8053 of file expr.cpp.

References SourcePos::Print().

TypeCheck()

Expr * SyncExpr::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 8058 of file expr.cpp.
