Detailed Description

Representation of a print() statement in the program.

It's currently necessary to have a special statement type for print() since strings aren't supported as first-class types in the language, but we need to be able to pass a formatting string as the first argument to print(). We also need this to be a variable argument function, which also isn't supported. Representing print() as a statement lets us work around both of those ugly little issues...

Constructor & Destructor Documentation

◆ PrintStmt()

PrintStmt::PrintStmt ( const std::string &  f,
Expr v,
SourcePos  p 

Definition at line 2902 of file stmt.cpp.

Member Function Documentation

◆ classof() [1/2]

static bool PrintStmt::classof ( PrintStmt const *  )

Definition at line 475 of file stmt.h.

◆ classof() [2/2]

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

◆ EmitCode()

void PrintStmt::EmitCode ( FunctionEmitContext ctx) const

◆ EstimateCost()

int PrintStmt::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 3092 of file stmt.cpp.

References COST_FUNCALL.

◆ Print()

void PrintStmt::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 3088 of file stmt.cpp.

References format.

◆ TypeCheck()

Stmt * PrintStmt::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 3090 of file stmt.cpp.

const std::string PrintStmt::format

Format string for the print() statement.

◆ values

Expr* PrintStmt::values

This holds the arguments passed to the print() statement. If more than one was provided, this will be an ExprList.
