* This checkin represents some cleanup of the backend, implementing the ↵Chris Lattner2001-09-141-1/+1
| | | | | | | | | | | | | | following things: 1. The TargetMachine structure is free to decide the process a particular target uses to generate code. 2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory. The Sparc.h file that is globally visible is just a stub. 3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort. NOTE! The BBLiveVar.cpp file dependant on the Sparc backend, and is therefore not generic/portale to other backends. This needs to be fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@558 91177308-0d34-0410-b5e6-96231b3b80d8
