I am running a C code on orpsoc under simulation.It has an array distances[8] to be processed.The statements:-
"distances[0]= sqrt(tmp);
rt_ptr=(int *)(&distances[0]);
report(*rt_ptr); "
works fine.but if I use any other element of the array instead of distance[0] it reports "0xxxxxxxxx".Why? What does this means?
Whereas
" distances[4]= sqrt(tmp);
b=distances[4];
rt_ptr=(int *)(&b);
report(*rt_ptr); "
works fine with all the elements.

One more issue.When I am using expf() or sqrt() statements inside a for loop.The make process gives me an error as "undefined reference to expf()/sqrt() respectively.I have unrolled the loop containing these functions and now no such error is being raised.Why can not these functions be associated with the loop variables?I am using Ubuntu OpenRISC Virtual Image.
