void ForeachActiveStmt::EmitCode ( FunctionEmitContext ctx) const
virtual

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

Implements Stmt.

int ForeachActiveStmt::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 2409 of file stmt.cpp.

References COST_VARYING_LOOP.

void ForeachActiveStmt::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 2375 of file stmt.cpp.

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

Stmt * ForeachActiveStmt::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 2400 of file stmt.cpp.

References sym.
