Subject: If we're emitting additional CIEs due to personality functions
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=d44fff7849034fc17d6a0e9f9926542865bb7881;p=oota-llvm.git

If we're emitting additional CIEs due to personality functions
don't emit the default one. Explicitly check for the NULL
CIE later.
