Subject: Suppress an annoying "unused variable" warning caused by bug 17897.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=415ae042c9a1964c7b61c39013cfc1b4a063f7d9;p=oota-llvm.git

Suppress an annoying "unused variable" warning caused by bug 17897.

Clang says that "flow" is unused when building LLD. This patch suppresses it.
