Duncan Sands 5f28475b30 Fix PR8445: a block with no predecessors may be the entry block, in which case ... it isn't unreachable and should not be zapped. The check for the entry block was missing in one case: a block containing a unwind instruction. While there, do some small cleanups: "M" is not a great name for a Function* (it would be more appropriate for a Module*), change it to "Fn"; use Fn in more places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117224 91177308-0d34-0410-b5e6-96231b3b80d8		2010-10-24 12:23:30 +00:00
