            Bug ID: 38121
           Summary: gcov profiling is broken on big endian machines
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: profile
          Assignee: unassignedbugs at nondot.org
          Reporter: mcastelluccio at mozilla.com

The tests I added in r336365 (two of which are supposed to pass both before and
after the patch) seem to fail on big endian machines, e.g. on s390x
(https://reviews.llvm.org/D48538#1154385) and on ppc64be because the hit counts
are wrong.
