Detailed Description

A "switch" statement in the program.

Definition at line 378 of file stmt.h.

Constructor & Destructor Documentation

◆ SwitchStmt()

SwitchStmt::SwitchStmt ( Expr expr,
Stmt stmts,
SourcePos  pos 

Definition at line 2495 of file stmt.cpp.

References expr, and stmts.

Member Function Documentation

◆ classof() [1/2]

static bool SwitchStmt::classof ( SwitchStmt const *  )

Definition at line 382 of file stmt.h.

◆ classof() [2/2]

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

◆ EmitCode()

void SwitchStmt::EmitCode ( FunctionEmitContext ctx) const

◆ EstimateCost()

int SwitchStmt::EstimateCost ( ) const

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 2667 of file stmt.cpp.

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

◆ Print()

void SwitchStmt::Print ( int  indent) const

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 2626 of file stmt.cpp.

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

◆ TypeCheck()

Stmt * SwitchStmt::TypeCheck ( )

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 2636 of file stmt.cpp.
