Subject: ELF2: SymbolBody::repl() never returns a nullptr.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2beabc9be5088c36dae9d6229181ec11d1406565;p=platform%2Fupstream%2Fllvm.git

ELF2: SymbolBody::repl() never returns a nullptr.

So we can use dyn_cast instead of dyn_cast_or_null here.
