+# Check the handling of multiple different CIEs. To have CIEs that
+# appear to be different, use a dwarf2 version of the file along with
+# a dwarf 4 version. The CIE header version (and layout) will be different.
+# FIXME: this test also checks that we didn't reuse the first CIE when it
+# appears again. This is a behavior we inherited from dsymutil-classic
+# but this should be fixed (see comment in patchFrameInfoForObject())
