e18a54c249 Use vectors instead of hash_maps for issueGaps and conflictLists.
These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.

a21e315db4 - Cleaned up the interface to AnalysisUsage to take analysis class names
instead of ::ID's.

4efbb9c931 A single MachineInstr operand may now be both a def and a use,
so additional dep. edges have to be added.
This was needed to correctly handle conditional move instructions!
MachineCodeForBasicBlock is now an annotation on BasicBlock.
Renamed "earliestForNode" to "earliestReadyTimeForNode".

536cf1b13f * Rename MethodPass class to FunctionPass
- 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

119c675af7 * Add a file header with some information
* Delete the DelaySlotInfo objects created by the SchedulingManager class.
  These leaked objects were accounting for 3/4 of the memory leaked by the
  backend, so this is a relatively major win.
* Reorganize SchedulingManager::getDelaySlotInfoForInstr so that it has
  better code locality (making it easier to read).

0cdcf40121 Add option to disable scheduling.
Destroy live-variable information after scheduling so it is
recomputed before later phases (e.g., reg. allocation).
Use deterministic iterator to enumerate sched graphs.

  InstrTypes.h anymore

dc3aec7a90 * 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.

9cd29563f0 * The itf exposed by InstrScheduling is now a single function to create the right pass
* InstructionScheduling is now a real pass
* InstrSched _uses_ LiveVar analysis, instead of creating it's own copy many times
  through a loop.  In this was LiveVarAnalysis is actually even SHARED by Register
  allocation.
* SchedPriorities is now passed the live var information in

180dee14b8 Bug fixes:
(1) Ensure that delay slot instructions are not moved out of place (this
    was happening for some CALL instructions).  Basically, we need to
    move all delay slot instructions out of the graph and handle them
    along with the delayed control transfer instruction.
(2) Mark scheduled instructions correctly when instructions are scheduled
    in more than one cycle in a single step (due to delay slots).

7e70cdb641 Checkin changes to:
1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.
