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.

Member Function Documentation

◆ classof() [1/2]

static bool CaseStmt::classof ( CaseStmt const *  )

Definition at line 345 of file stmt.h.

◆ classof() [2/2]

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

◆ EmitCode()

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 2453 of file stmt.cpp.

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

◆ EstimateCost()

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 2468 of file stmt.cpp.

◆ Print()

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 2459 of file stmt.cpp.

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

◆ TypeCheck()

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.

Definition at line 2466 of file stmt.cpp.
