static bool SwitchStmt::classof ( SwitchStmt const *  )
inlinestatic

Definition at line 434 of file stmt.h.

static bool SwitchStmt::classof ( ASTNode const *  N)
inlinestatic

Definition at line 435 of file stmt.h.

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

void SwitchStmt::EmitCode ( FunctionEmitContext ctx) const
virtual
int SwitchStmt::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 2950 of file stmt.cpp.

References COST_UNIFORM_SWITCH, COST_VARYING_SWITCH, expr, Expr::GetType(), and Type::IsVaryingType().

void SwitchStmt::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 2905 of file stmt.cpp.

References expr, ASTNode::pos, Stmt::Print(), Expr::Print(), SourcePos::Print(), and stmts.

Stmt * SwitchStmt::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 2917 of file stmt.cpp.
