Subject: InstrProf: Add a test for PR22531
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=830605fd9a90c933da058be4003da58b7b760e7e;p=clang

InstrProf: Add a test for PR22531

This is a test for the llvm change in r228793. We need to make sure
that names referred to by coverage end up in the right section, or the
coverage tools won't work.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@228794 91177308-0d34-0410-b5e6-96231b3b80d8
