Well for the RTL level, with this code, one problem is that iv-opts messes up:
ivtmp.34 = (long unsigned int) &(*(b + 64))[j];
There is a bug for the iv-opts issue too (though I have not had time to look
into fixing it the correct way, iv-opts needs a real rewrite).
And also PRE does not remap the pretmp for restrict (this already filed).
