Subject: Tighten up the specification to allow TableGen/nested-comment.td to pass
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;ds=sidebyside;h=997833247376a710e09b946e8a96c50859622c75;p=oota-llvm.git

Tighten up the specification to allow TableGen/nested-comment.td to pass
(fixing a bug where / in a /* */ comment would cause it to not close).
