Chris Lattner 9810b94850 Fix several bugs: 
* Warnings were emitted all of the time and were really annoying
  * Functions could not be resolved unless they had external linkage.  Linkonce
    linkage was not allowed
  * ConstantPointerRef's were not handled when linking functions
    we now actually handle cast (CPR) to X -> cast (NewCPR) to X

Chris Lattner 3c98276168 Fix major problem with PHI node traversal: rechecking PHIs should go into 
the visit function.  The worklist is for when their lattice value changes.

Chris Lattner 65e5f653fd Big programs have tons of global variable initializers, and most passes don't care 
about them.  Try to delete them if it doesn't affect the passes.

llvm-svn: 5915
 2003-04-24 23:51:38 +00:00
Chris Lattner de39f2bdac The big fix is this change: 
-    if (I->isExternal() && !Functions.count(I))
+    if (!I->isExternal() && !Functions.count(I))

We were not actually deleting any functions from the module!
