------- Comment #4 from jakub at gcc dot gnu dot org 2009-11-06 10:22 -------
The only difference on the attached testcase between vanilla 4.4 branch and
4.4-RH is unwind info, in particular epilogue unwind info. The testcase never
throws, so I don't think it matters.
With -fno-exceptions -fno-asynchronous-unwind-tables the generated assembly is
identical (in both cases from x86_64-linux -> s390x-linux cross).
I'm now grabbing a real s390x box to see whether the testcase actually fails at
runtime...
