            Bug ID: 32038
           Summary: sumarray2d test fails with mavx flag
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

                CC: llvm-bugs at lists.llvm.org

SingleSource/Regression/C/sumarray2d test failed when compiled with O3 flto
mavx.  The test passes without mavx flag. 

I shall further try to root cause the issue / find svn revision that introduced
this issue.


Output difference:

SingleSource/Regression/C$ cat Output/sumarray2d.out-nat
Sum(Array[100,100] = 975150
exit 0
SingleSource/Regression/C$ cat Output/sumarray2d.out-simple
Sum(Array[100,100] = -14747
exit 0
