Hmmm does -O3 overrides -fno-vect-cost-model?
When I running the testsuite with qemu/-fno-vect-cost-model (as target board),
my logs show:
[...]
/home/christophe.lyon/src/GCC/sources/gcc-fsf/r197671/gcc/testsuite/gfortran.fortran-torture/execute/in-pack.f90
-fno-vect-cost-model -fno-diagnostics-show-caret -w -O3 -g [....]
so I may not have been testing what I thought :(
