Subject: Fix a few more places to use PadToColumn instead of tabs. And fix
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e45da0dce0af2d6254c7db63a2fe0c3501dd3a5a;p=oota-llvm.git

Fix a few more places to use PadToColumn instead of tabs. And fix
the basic block label printing to check whether a block has a name
before printing a comment character and whitespace for it.
