2004-06-29The code generator should work with unreachable blocks. If not, then thisChris Lattner
is a bug that should be fixed in the code generator, not papered over with the simplifycfg pass. Eliminating this makes bugpoint much more useful git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14477 91177308-0d34-0410-b5e6-96231b3b80d8
