Convert backward conversion of expression trees into a new more powerful bidirectional approach.  Add transforms for more instructions.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1121 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed instruction information for RDCCR and WRCCR.
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).

Minor method rename

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1119 91177308-0d34-0410-b5e6-96231b3b80d8

Add transformations for Load and GetElementPtr.  Fix broken transform with shr.

Fix cast instructions that end up in bad places in GCC output

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1117 91177308-0d34-0410-b5e6-96231b3b80d8

Added an assertion since it seems like AdjList returns an errornous size in method
IGNode::pushOnStack().

Avoid making a broken transformation!

Add new cleanup pass:
//  1. PHI nodes with multiple entries for the same predecessor.  GCC sometimes
//     generates code that looks like this:
//
//  bb7:  br bool %cond1004, label %bb8, label %bb8
//  bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ]
//
//     which is completely illegal LLVM code.  To compensate for this, we insert
//     an extra basic block, and convert the code to look like this:
//
//  bb7: br bool %cond1004, label %bbX, label %bb8
//  bbX: br label bb8
//  bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]
//

Add a helper function to PHI node

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1113 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for correct spilling of %ccr

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1112 91177308-0d34-0410-b5e6-96231b3b80d8

Added code to support correct saving of %ccr across calls

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1111 91177308-0d34-0410-b5e6-96231b3b80d8

* Export method to merge identically named methods
* Add code to fix PHI nodes that are missing arguments.  These PHI nodes can
  be generated by GCC if there is an uninitialized variable flowing into a merge
  point.  For example:

int foo(int y) {
  int X;
  if (y) X = 1;
  return X;
}

Expose method to merge identically named methods

Arranged stack frame - needs furhter organization

Moved InsertCallerSaveInstr to the SparcRegInfo.cpp and made machine independent
