with the classname anyways. * Add an isPHINode() method to Instruction * Add getUniqueName() to SymbolTable class * Add an insert method to ValueHolder git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73 91177308-0d34-0410-b5e6-96231b3b80d8

// This defines a class that is used as a fancy Definition container. It is

// special because it helps keep the symbol table of the container method up to
|
|
// date with the goings on inside of it.
|
|
//
|
|
// This is used to represent things like the instructions of a basic block and
|

// the arguments to a method.
