2004-09-01Changes For Bug 352Reid Spencer
Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16137 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-06Fix a bug in the unreachable block elim pass. Dropping all references on aChris Lattner
basic block clear()'s all of the operands lists, including phis. This caused removePredecessor to get confused later. Because of this, we just nuke (without prejudice) PHI nodes in unreachable blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14635 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-02Add a trivially simple pass to delete unreachable blocks from the CFG. ThisChris Lattner
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
