void ForeachUniqueStmt::EmitCode ( FunctionEmitContext ctx) const
virtual

Emit LLVM IR for the statement, using the FunctionEmitContext to create the necessary instructions.

Implements Stmt.

int ForeachUniqueStmt::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 2657 of file stmt.cpp.

References COST_VARYING_LOOP.

void ForeachUniqueStmt::Print ( int  indent) const
virtual

Print a representation of the statement (and any children AST nodes) to standard output. This method is used for debuggins.

Implements Stmt.

Definition at line 2601 of file stmt.cpp.

References expr, Type::GetString(), Symbol::name, ASTNode::pos, Stmt::Print(), Expr::Print(), SourcePos::Print(), stmts, sym, and Symbol::type.

Stmt * ForeachUniqueStmt::TypeCheck ( )
virtual

Type checking should be performed by the node when this method is called. In the event of an error, a NULL value may be returned. As with ASTNode::Optimize(), the caller should store the returned pointer in place of the original ASTNode *.

Implements Stmt.

Definition at line 2633 of file stmt.cpp.

References Error(), expr, Type::GetString(), Expr::GetType(), Type::IsBasicType(), Type::IsVaryingType(), ASTNode::pos, and sym.
