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 8487 of file expr.cpp.

References COST_SYNC.

const Type * SyncExpr::GetType ( ) const
virtual

Returns the Type of the expression.

Implements Expr.

Definition at line 8473 of file expr.cpp.

References AtomicType::Void.

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 8479 of file expr.cpp.

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

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 8506 of file expr.cpp.

void SyncExpr::Print ( ) const
virtual

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

Implements Expr.

Definition at line 8493 of file expr.cpp.

References SourcePos::Print().

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 8500 of file expr.cpp.
