Chris Lattner f2a738cfe2 * ValueHolder now takes 3 arguments
* Added a few methods to ConstantPool
* ConstPoolVal no longer derives from Value
* Method & Module multiply inherit from SymTabValue & Value now
* Added a GetElementPtrInst::isStructSelector() method

llvm-svn: 178
2001-07-14 06:08:51 +00:00
Chris Lattner 5a2d2b1f0a Made the following changes:
* ValueHolder became a 3 argument template.  This allows for BasicBlock to
  use the value holder arg as a typesafe parent pointer.
* SymTabValue no longer inherits from Value
* Method does not inherit from only SymTabValue.  Now it inherits from both
  STV & Value.
* Module does not inherit from only SymTabValue.  Now it inherits from both
  STV & Value.
* Updated the SymTabValue.h file to reference SymTabValue instead of STDef
  in several places
* Added isArraySelector & isStructSelector to GetElementPtr instruction
