routines supporting machine code optimization.
Also added method MachineInstrInfo::getNOPOpCode().

llvm-svn: 3845

TargetMachine.cpp, since it is entirely machine-independent.
Also, add options to disable optional back-end passes (preselection and
instr. scheduling).

to make debugging output a lot nicer.

  - Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well

llvm-svn: 2333

Freeze auto vars and spill areas when their sizes are used
for computing other offsets.

llvm-svn: 2317

* Move InsertPrologEpilogCode class to PrologEpilogCodeInserter.cpp
   -> Among other things, this eliminates the need for the minstrVec static
      global array.

class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

llvm-svn: 2144

Also re-enable instr. scheduling pass.

  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

llvm-svn: 1750

Method::inst_* is now in llvm/Support/InstIterator.h
GraphTraits specializations for BasicBlock and Methods are now in llvm/Support/CFG.h

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

llvm-svn: 1681

* 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).

Eventually they will probably get moved again, but at least now they aren't
having to be compiled by 7 different .cpp files...

llvm-svn: 1666

Convert some stages into passes in preparation for more splitting up.
Try to decouple stuff as much as possible.

llvm-svn: 1663

* Implement memory freeing for instruction temporaries
