* Fix two pretty serious bugs:Chris Lattner2004-04-02
| | | | | | | | | | | | | 1. Each time the loop extractor extracted a loop, we would leak a module. 2. When we extracted a loop, we didn't add the new function to the list of miscompiled functions. Thus if the bug was in a loop nest and we extracted it, we could actually *LOSE THE BUG*, which is very bad. With these patches, bugpoint has successfully found a bug for me in a function with several nested loops, and cut it down to just one of them. :) :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12605 91177308-0d34-0410-b5e6-96231b3b80d8
