llvm-svn: 1466
2001-12-14 16:38:04 +00:00
Chris Lattner b457653c6f * Support pointer indexing
* Unsized arrays are a thing of the past, remove DoInsertArrayCast family
* Remove cases were we would get into infinite loops because we would insert a cast
  which would then be removed, inserting a different cast, ad infinitum...
* Remove some code that should be redundant with ExprTypeConvert code

llvm-svn: 1465
2001-12-14 16:37:52 +00:00
Chris Lattner 3e88b44afc Many many changes and bugfixes:

  and should be fixed in the future)
* Allow more and better conversions

2001-12-14 16:32:20 +00:00
Chris Lattner f1197b0d43 * Refactor trace values to work as a proper pass. Before it used to add
methods while the pass was running which was a no no.  Now it adds the
  printf method at pass initialization
* Revamp code to use printf calls instead of the old style print_<type>
  calls.
* Simplify code

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;
}

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 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.  :)

* 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
