So obviously a bunch of symbols relating to x86_64 are gone...
That last one for "cfiStartsArray[i] != cfiStartsArray[i-1]" is
interesting as it comes from:
#ifndef NDEBUG
// scan for FDEs claming the same function
for(int i=1; i < index; ++i) {
assert( cfiStartsArray[i] != cfiStartsArray[i-1]
);
}
#endif
