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...

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

Chris Lattner ef99d3c144 * Fix cases where we were calling Type->getName() instead of Type->getDescription()

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
