           Summary: Test script tries to compile source code with
                    "-mthumb" option when running test gcc.dg/binop-xor1.c
                    for powerpc64
           Product: gcc
           Version: 4.9.1
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

When running the test suite for powerpc64 the "gcc.dg/binop-xor1.c" test fails
with the following output:

It seems that the test suite is trying to compile code for ARM with a PPC64
compiler.
