Chris Lattner 34f8595c0b Add a helper function to PHI node 
llvm-svn: 1113
 2001-11-03 21:08:00 +00:00
Ruchira Sasanka 51fc1c2d72 Added support for correct spilling of %ccr

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;
}

Chris Lattner d7c742f46a Be lenient on types so that programs that are not very typesafe will work

Chris Lattner 629d7a7849 Changes to compile the TSP benchmark successfully. Favor warning instead of assertion failures.

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 866cbddec8 Dramatically simplify recursive type processing. Fixed a few bugs, a few still remain :( 
Why does this stuff have to come up NOW?

Chris Lattner e80af939da Print floating point numbers in expodential form so that small numbers don't get truncated, which broke the health benchmark

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
