Chris Lattner 4f0f09757d Pull RaiseAllocations stuff out of the CleanGCC pass into it's own pass in 
the ChangeAllocations.h header file.

Chris Lattner 0686e435d1 Implement a more powerful, simpler, pass system. This pass system can figure 
out how to run a collection of passes optimially given their behaviors and
charactaristics.

Convert code to use it.

Chris Lattner ec83fc091e 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 ]
//

Chris Lattner 784c623efb * 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;
}

llvm-svn: 1103
 2001-11-03 10:04:22 +00:00
Chris Lattner 1f3947c1d1 Add code to link method together with the same name if one is vararg and the other isn't. 
This resolves definitions like this:
   %list * "foo"(...)
   %list * "foo"(int)

together which can often occur because C programmers don't put prototypes in like they should.  GRR

Chris Lattner a073acb22d Changed the fundemental architecture of Operands for Instructions. Now 
Operands are maintained as a vector<Use> in the User class, and operator
iterators are provided as before.  Getting an operand no longer requires
a virtual function call.

WARNING: getOperand(x) where x >= getNumOperands() will now assert instead
of returning null!
