Chris Lattner 54e9f453c9 * Add better caching of data to avoid silly recusions 
* Only check to see if uses of instructions can be converted for expressions... so we don't look at all of the uses of a constant.  This was making the code unnecessarily conservative

llvm-svn: 1179
 2001-11-07 20:12:30 +00:00
Chris Lattner 31e9e4d219 * Switch to operation on pointers with PointerTy more consistently 
* Fix misspeling
* Catch SIGFPE for traps
* info XXX now prints the raw contents of the GenericValue
* Switch to calloc instead of malloc (temporarily I hope) to bandaid Olden benchmarks
* Implement binary And & Or
* Convert expressions like this:
     PointerTy SrcPtr = getOperandValue(I->getPtrOperand(), SF).PointerVal;
  to:
    GenericValue SRC = getOperandValue(I->getPtrOperand(), SF);
    PointerTy SrcPtr = SRC.PointerVal;
  because the prior way confuses purify.
* Taint the initial values of the value planes
* Handling 'print bb4' in the interpreter without crashing
* Print nicer stack frames with concise return type
* printf doesn't suck nearly as badly as it used to

//
//     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

Chris Lattner 784c623efb * Export method to merge identically named methods 
* Add code to fix PHI nodes that are missing arguments.  These PHI nodes can

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

Chris Lattner 9bc6b190cc * Add comments for peepholes

     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //
     // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
     //       %t1 = cast <eltype> * %t1 to <ty> *

  This peephole eliminated 9 evil casts in the health benchmark, and
  completely turned the addList method around.  :)
