           Summary: [powerpc-nofpu] remainderl wrong sign of zero result
           Product: glibc

            Status: NEW
          Severity: normal

For soft-float powerpc, the remainderl function produces zero results with the
wrong sign for various inputs.  A representative example is:

Failure: Test: remainder (-2, 1)
Result:
 is:          0.00000000000000000000000000000000e+00  
0x0.000000000000000000000000000p+0
 should be:  -0.00000000000000000000000000000000e+00 
-0x0.000000000000000000000000000p+0
 difference:  0.00000000000000000000000000000000e+00  
0x0.000000000000000000000000000p+0
 ulp       :  0.0000
 max.ulp   :  0.0000
