Subject: llvm-profdata: Avoid writing to /dev/null in tests
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=aae82fb2f7617fb969180b759b43c636104d1670;p=oota-llvm.git

llvm-profdata: Avoid writing to /dev/null in tests

We fseek on our output file in llvm-profdata, which errors on some
systems. Avoid getting into the situation by writing to /dev/null

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206670 91177308-0d34-0410-b5e6-96231b3b80d8
