◆ EmitCode()
|
virtual |
Emit LLVM IR for the statement, using the FunctionEmitContext to create the necessary instructions.
Implements Stmt.

◆ EstimateCost()
|
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.

◆ Print()
|
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 901 of file stmt.cpp.
References bodyStmts, ASTNode::pos, Stmt::Print(), Expr::Print(), SourcePos::Print(), and testExpr.
◆ 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.
