Member Function Documentation

classof() [1/2]

static bool LabeledStmt::classof ( LabeledStmt const *  )

inlinestatic

Definition at line 422 of file stmt.h.

classof() [2/2]

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

inlinestatic

Definition at line 423 of file stmt.h.

References Stmt::EmitCode(), ASTNode::EstimateCost(), ASTNode::getValueID(), ASTNode::LabeledStmtID, Stmt::Optimize(), Stmt::Print(), and Stmt::TypeCheck().

EmitCode()

void LabeledStmt::EmitCode ( FunctionEmitContext *  ctx ) const

virtual

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

Implements Stmt.

Definition at line 2530 of file stmt.cpp.

References AssertPos, FunctionEmitContext::BranchInst(), Stmt::EmitCode(), FunctionEmitContext::GetCurrentBasicBlock(), FunctionEmitContext::GetLabeledBasicBlock(), name, ASTNode::pos, FunctionEmitContext::SetCurrentBasicBlock(), and stmt.

EstimateCost()

int LabeledStmt::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 2569 of file stmt.cpp.

Optimize()

Stmt * LabeledStmt::Optimize ( )

virtual

The Optimize() method should perform any appropriate early-stage optimizations on the node (e.g. constant folding). This method will be called after the node's children have already been optimized, and the caller will store the returned ASTNode * in place of the original node. This method should return NULL if an error is encountered during optimization.

Reimplemented from Stmt.

Definition at line 2553 of file stmt.cpp.

Print()

void LabeledStmt::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 2547 of file stmt.cpp.

References name, Stmt::Print(), and stmt.

TypeCheck()

Stmt * LabeledStmt::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 2555 of file stmt.cpp.

References Error(), name, and ASTNode::pos.
