Re: Usage of -ftrapv

[Paulo Matos]

As an addition to my original post: for example,
#include <iostream>
#include <limits>

int main() {

  unsigned int maxi = std::numeric_limits<unsigned int>::max();

  maxi++;

  std::cerr <<  "Value of maxi after sum: " << maxi << std::endl;

  return 0;

}

after compiled with or with -ftrapv g++ generates binary executables
which are exactly the same:
pmatos@euler ~ $ g++ -o ftrapvw ftrapv.cc
pmatos@euler ~ $ g++ -ftrapv -o ftrapv ftrapv.cc
pmatos@euler ~ $ md5sum ftrapv
fa2b15c2dccf7d721ae883cea1e5190e  ftrapv
pmatos@euler ~ $ md5sum ftrapvw
fa2b15c2dccf7d721ae883cea1e5190e  ftrapvw

What's the problem after all?

Cheers,
