Chris Lattner 071dea7362 * Remove the concept of a critical shadow node

Chris Lattner 46b08cdc7c * Eliminate ArgDSNode's completely, now rely on scalar map
* Fold call nodes that are indistinguishable for each other.  This is a big
  win for external functions like sqrt, which would multiply dramatically
  before.

Chris Lattner d63afb418e Unify the destruction code used for node pairs vs normal nodes. This was
causing a problem before because global values with incoming edges didn't
copy the incoming edges to the node they were being merged from, causing
the poolalloc pass to die.

Chris Lattner b1782d0c90 Many changes

llvm-svn: 562
2001-09-14 03:55:11 +00:00
Chris Lattner ff0c8a7511 This checkin represents some cleanup of the backend, implementing the 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.
