Comment 1 Yao Qi 2006-08-05 07:12:48 UTC 
In lib/dw/tests/cni/TestLib.cxx, 
jlong
lib::dw::tests::TestLib::getFuncAddr(){
        return (jlong) &getFuncAddr;
}

&getFuncAddr is only a function descriptor instead of function entry address ,
and the real entry address is the "dot" symbol(specified in PowerPC 64-bit ABI
documentation).

Still investigate how to get function entry address in source code on PowerPC64.
