The test case runs long enough to time out.  I tried one by hand and it ran at
least an hour before I killed it.

    testsuite/108604 - gcc.dg/torture/pr108574-3.c hangs on unsigned char archs

    In the architecture where sign defaults to unsigned, the 'f' will be zero
    extended to int type in the expression 'd = ~(f & ~2880764155)', then the
    'd' will become -1 wich cause the case to fail.
    So it's ok for the architectures where sign defaults to signed like x86,
    but failed for the architectures where sign defaults to unsigned like arm
    and csky. Change char to signed char to avoid this problem.

            PR testsuite/108604
    gcc/testsuite:
            * gcc.dg/torture/pr108574-3.c (b, f): Change type from char to
            signed char.
