Detailed Description
A list of expressions.
These are mostly used for representing curly-brace delimited initializers for initializers for complex types and for representing the arguments passed to a function call.

| llvm::Constant * ExprList::GetConstant | ( | const Type * | type | ) | const [virtual] |
If this is a constant expression that can be converted to a constant of the given type, this method should return the corresponding llvm::Constant value. Otherwise it should return NULL.
Reimplemented from Expr.

| const Type * ExprList::GetType | ( | ) | const [virtual] |
| llvm::Value * ExprList::GetValue | ( | FunctionEmitContext * | ctx | ) | const [virtual] |
This is the main method for Expr implementations to implement. It should call methods in the FunctionEmitContext to emit LLVM IR instructions to the current basic block in order to generate an llvm::Value that represents the expression's value.
Implements Expr.
| ExprList * ExprList::Optimize | ( | ) | [virtual] |
This method should perform early optimizations of the expression (constant folding, etc.) and return a pointer to the resulting expression. If an error is encountered during optimization, NULL should be returned.
Implements Expr.

| void ExprList::Print | ( | ) | const [virtual] |
Prints the expression to standard output (used for debugging).
