full-expression. Naturally they're inactive before we enter the block literal expression. This restores the intended behavior that blocks belong to their enclosing scope. There's a useful -O0 / compile-time optimization that we're missing here with activating cleanups following straight-line code from their inactive beginnings. llvm-svn: 144268
