e282c0b592 Convert operand iterator over to work like an STL iterator 
llvm-svn: 1720
 2002-02-05 06:02:59 +00:00

5337fbec40 Minor change: Methods that return ValueSet's that are guaranteed to be valid 
return references instead of pointers.

862fab4da7 * Code Cleanups 
* Removal dependencies on Type.h & remove uses of getTypeID()

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

a8170f0944 * Code Cleanups

817f1768d4 * RegisterAllocation _uses_ LiveVar analysis, instead of creating it's own copy

e264071f46 Switch register allocator over to using LoopInfo directly instead of indirectly through LoopDepthCalculator 
llvm-svn: 1696
 2002-02-04 17:48:00 +00:00
Chris Lattner
bb19367753 Make LoopDeptCalculator be an internal artifact of how RegAlloc is implemented, 
do not expose it.  Additionally, have it be auto generated by the pass framework
for us.

f3f13580e9 * Add #includes removed from headers

8bfb48c8d3 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.

9a8ff2595a Split RegisterAllocation stuff OUT of Sparc.cpp into a well defined pass 
that has a very minimal interface (like it should have).

b1e6823bc1 Fixed a bug concering LR spilling. Earlier, added spilled code was not inserted 
into the instruction stream correctly.

3df85d6132 Do the same for allocating spills to get their alignment right too.

 2001-11-12 23:40:22 +00:00

af9c0a766a When allocating space on stack for writing a register, 
use the size of the register, not the size of the Value type,
to get the right alignment.
