All,
I am getting a lot of test suite failures with almost all of
the vect/* tests. I am using pr18400.c from the test suite
as an example here, becuase its about the smallest one I
can find. Here is what is generated at -O2:
Can you try -fno-optimize-sibling-calls and see if that works?
If so, then the problem is that we sibling calls should not be
done in main. To fix the testcase anyways to be correct is to
put "return 0;" after the call to main1. Since right now the
return of main could be anything.
Thanks,
