Member Function Documentation

classof() [1/2]

static bool DeleteStmt::classof ( DeleteStmt const *  )

inlinestatic

Definition at line 523 of file stmt.h.

classof() [2/2]

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

inlinestatic

Definition at line 524 of file stmt.h.

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

EmitCode()

void DeleteStmt::EmitCode ( FunctionEmitContext *  ctx ) const

virtual

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

Implements Stmt.

Definition at line 2850 of file stmt.cpp.

References AssertPos, FunctionEmitContext::BitCastInst(), FunctionEmitContext::CallInst(), Module::errorCount, expr, g, FunctionEmitContext::GetCurrentBasicBlock(), Expr::GetType(), Expr::GetValue(), LLVMTypes::Int64VectorType, Target::is32Bit(), Type::IsUniformType(), m, Module::module, ASTNode::pos, Globals::target, LLVMTypes::VoidPointerType, and FunctionEmitContext::ZExtInst().

EstimateCost()

int DeleteStmt::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 2916 of file stmt.cpp.

References COST_DELETE.

Print()

void DeleteStmt::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 2901 of file stmt.cpp.

TypeCheck()

Stmt * DeleteStmt::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 2903 of file stmt.cpp.

References Error(), expr, Type::GetString(), Expr::GetType(), and ASTNode::pos.

Member Data Documentation

expr

Expr* DeleteStmt::expr

Expression that gives the pointer value to be deleted.
