Detailed Description

Statement corresponding to a "case" label in the program. In addition to the value associated with the "case", this statement also stores the statements following it.

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

Definition at line 392 of file stmt.h.

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

void CaseStmt::EmitCode ( FunctionEmitContext ctx) const

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

Implements Stmt.

Definition at line 2693 of file stmt.cpp.

References FunctionEmitContext::EmitCaseLabel(), Stmt::EmitCode(), lCheckMask(), ASTNode::pos, and stmts.

int CaseStmt::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 2716 of file stmt.cpp.

void CaseStmt::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 2701 of file stmt.cpp.

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

Stmt * CaseStmt::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.
