            Bug ID: 49558
           Summary: TokensTest.cpp has an un-executed EXPECT_THAT test
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Tooling
          Assignee: unassignedclangbugs at nondot.org
          Reporter: paul_robinson at playstation.sony.com
                CC: llvm-bugs at lists.llvm.org

clang/unittests/Tooling/Syntax/TokensTest.cpp has a test "Locations" that
ends with the following loop:

  for (auto &R : Code.ranges()) {
    EXPECT_THAT(Buffer.spelledTokenAt(StartLoc.getLocWithOffset(R.Begin)),
                Pointee(RangeIs(R)));
  }

However, the EXPECT_THAT is never executed (replacing it with an assert or
llvm_unreachable does not fire).  Apparently Code.ranges() has no elements.
