static bool ExprStmt::classof ( ExprStmt const *  )
inlinestatic

Definition at line 81 of file stmt.h.

static bool ExprStmt::classof ( ASTNode const *  N)
inlinestatic

Definition at line 82 of file stmt.h.

References ASTNode::ExprStmtID, and ASTNode::getValueID().

void ExprStmt::EmitCode ( FunctionEmitContext ctx) const
virtual

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

Implements Stmt.

Definition at line 90 of file stmt.cpp.

References expr, FunctionEmitContext::GetCurrentBasicBlock(), Expr::GetValue(), ASTNode::pos, and FunctionEmitContext::SetDebugPos().

int ExprStmt::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 120 of file stmt.cpp.

void ExprStmt::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 107 of file stmt.cpp.

References expr, ASTNode::pos, Expr::Print(), and SourcePos::Print().

Stmt * ExprStmt::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 101 of file stmt.cpp.
