Is this an CPU that supports the e500 instruction set extension?
I suspect it is. Valgrind doesn't support e500 instructions.
But what is strange about this ...

.. is that it looks like Valgrind itself SIGILL'd. The address
0x38033634 is probably inside
/home/honglinc/local/valgrind/lib/valgrind/memcheck-ppc32-linux
and you should be able to find out what the failing instruction
is and which function it is in, using objdump on that file.
