Chris Lattner 0cd962fa61 * Change ExpressionConvertableToType to more closely match map behavior of 
ConvertExpressionToType
* Make ValueHandle's remove instruction from maps when they are deleted so that
  no false map hits occur if a subsequent instruction is allocated to the same
  space in memory.  This was a VERY VERY VERY EVIL NASTY BUG to track down. :-P

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: 1115
 2001-11-03 21:30:22 +00:00
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 ]
//

llvm-svn: 1114
 2001-11-03 21:08:59 +00:00
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: 1110
 2001-11-03 19:51:56 +00:00
Ruchira Sasanka 629a15247a Commented out code so that copies are inserted for all phi args

 2001-11-03 17:09:59 +00:00
Chris Lattner 629d7a7849 Changes to compile the TSP benchmark successfully. Favor warning instead of assertion failures. 
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

llvm-svn: 1102
 2001-11-03 09:19:00 +00:00
Chris Lattner 3855f2c806 Don't forget to link type names together too. Fix for Olden/mst benchmark

llvm-svn: 1091
 2001-11-03 03:27:29 +00:00
Chris Lattner 9bc6b190cc * Add comments for peepholes 
* Implement new peephole:
     // 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.  :)

Chris Lattner 9a13ececd8 * Implement expression type conversion for constant values 
* Fix a problem setting a name on a constant value that died because no symbol table was passed in
* Add some comments describing the passes
* Implement a new peephole:
     // Peephole optimize the following instructions:
     // %t = cast <T1>* %P to <T2> * ;; If T1 is losslessly convertable to T2
     // store <T2> %V, <T2>* %t
     //
     // Into:
     // %t = cast <T2> %V to <T1>
     // store <T1> %t2, <T1>* %P

Chris Lattner a0a8b5bc26 Massive hacks to try to fix subtle logic bugs. I think it's all working now,

Chris Lattner b1ca9cbceb Broad superficial changes: 
* Renamed getOpcode to getOpcodeName
* Changed getOpcodeName to return a const char * instead of string
* Added a getOpcode method to replace getInstType
* Changed code to use getOpcode instead of getInstType

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!
