fpcmp + conflicting files
The attached example (result from an ARM run of sqlite3) shows that fpcmp is
comparing different lines (one immediate after the other) in both mixed and
pure FP outputs.
$ ./fpcmp -r 1.0e-9 sqlite3.out-nat.fp sqlite3.out-simple.fp
./fpcmp: Compared: 2.616701e+05 and 2.573593e+05
abs. diff = 4.310775e+03 rel.diff = 1.675002e-02
Out of tolerance: rel/abs: 1.000000e-09/0.000000e+00
$ ./fpcmp -r 1.0e-9 sqlite3.out-nat sqlite3.out-simple
./fpcmp: Compared: 4.910000e+02 and 2.573593e+05
abs. diff = 2.568683e+05 rel.diff = 9.980922e-01
Out of tolerance: rel/abs: 1.000000e-09/0.000000e+00</pre>
