Member Function Documentation

int SeExpr2::ExprCompareNode::buildInterpreter ( Interpreter interpreter) const
virtual LLVM_VALUE SeExpr2::ExprCompareNode::codegen ( LLVM_BUILDER  )

Reimplemented from SeExpr2::ExprNode.

ExprType SeExpr2::ExprCompareNode::prep ( bool  dontNeedScalar,
ExprVarEnvBuilder envBuilder 

Prepare the node (for parser use only). See the discussion at the start of SeExprNode.cpp for more info.

Default is to call prep on children (giving AnyType as desired type). If all children return valid types, returns NoneType. Otherwise, returns ErrorType. Note: Ignores wanted type.
