Chris Lattner b0af9cdbda * 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

Chris Lattner f48173a875 Convert RegisterAllocator interface to opaque pass type, so that users do not 
need to know _anything_ about RegAlloc to use it.  Well in the end maybe.

Chris Lattner 5216cc55f7 * 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

Chris Lattner 64593c51bb 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...

Vikram S. Adve 6c697526bf 1. Move most of the constant-fixup code into machine-independent file 
InstrSelectionSupport.cpp.  It now happens in a bottom-up pass on
   each BURG tree after the original top-down selection pass on the tree.
2. Handle global values as constants (viz., constant addresses).

llvm-svn: 794
 2001-10-14 17:26:21 +00:00
Chris Lattner 1a176f15dc Make the sparc.burg file be a little more flexible and rubust in the fact of 
renumbering of instructions.  It is still horribly broken and grossly dependant on the number of instructions, but now it is a least a little better.

Oh yeah it also works now.

Vikram S. Adve 3652ef7587 Several fixes: 
(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".

Chris Lattner f8464e4b8d 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.
