8ada4c031e Bug re-fix: put back MachineCodeForInstruction::get(*I).dropAllReferences(). 
Also re-enable instr. scheduling pass.

57d735db7a Major enhancements to how array and structure indices are handled. 
Improve checking for constants in Multiply.
Simpler method to keep track of when a node is folded into its parent.
Several other bug fixes.

7f139ccf85 Add support for code generation for array references. 
Also, use distinct names for the three types of SetMachineOperand to
avoid painful overloading problems and errors.
Bug fix in converting-int-to-float.  Other minor stuff.

217f7b1fe1 Bug fixes for not using unified reg. numbers, and for using the 
wrong register class for saving CC registers.
Also, use distinct names for the three types of SetMachineOperand.

23d4011ea1 Handling of global names was severely broken when converting to 2 passes. 
Different labels were generated for the same name in different passes.
Use an annotation to hold a fixed table of names.

8e9be000a7 * Pull BasicBlock::pred_* and BasicBlock::succ_* out of BasicBlock.h and into 
llvm/Support/CFG.h
* Make pred & succ iterators for intervals global functions
* Add #includes that are now neccesary because BasicBlock.h doesn't include
  InstrTypes.h anymore

f3d0ae9fdb * Eliminate the LiveVarSet class, making applyTranferFuncForMInst a static 
function in the one .cpp file that uses it.  Use ValueSet's instead.
* Prepare to delete LiveVarSet.h & LiveVarSet.cpp
* Eliminate the ValueSet class, making all old member functions into global
  templates that will eventually be moved to Support.
* Eliminate some irrelevant const's

need to know _anything_ about RegAlloc to use it.  Well in the end maybe.

4c0bf66bdd * Minor cleanups 
* Reduce number of #includes
* Remove blatently misleading qualifiers (how do you have an inlined pure virtual function?)
* Remove unnecesary & ignored qualifiers (const int argument vs int argument)
* SparcInternals.h now no longer #includes RegClass.h or SparcRegClassInfo.h
* Pull inlined functions out of .h file if they are virtual and interfere with dependencies

that has a very minimal interface (like it should have).

78017556fc Move a ton of tables out of SparcInternals.h and move them to Sparc.cpp. 
Eventually they will probably get moved again, but at least now they aren't
having to be compiled by 7 different .cpp files...
