Chris Lattner fc3c82a804 Add a trivially simple pass to delete unreachable blocks from the CFG. This ... pass is required to paper over problems in the code generator (primarily live variables and its clients) which doesn't really have any well defined semantics for unreachable code. The proper solution to this problem is to have instruction selectors not select blocks that are unreachable. Until we have a instruction selection framework available for use, however, we can't expect all instruction selector writers to do this. Until then, this pass should be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14563 91177308-0d34-0410-b5e6-96231b3b80d8		2004-07-02 05:46:10 +00:00
