# Optimization flags
####################

# -Ofast                  : Disregard strict standards compliance. Enables all -O3 optimizations.
#                           It also enables optimizations that are not valid
#                           for all standard-compliant programs.  It turns on
#                           -ffast-math and the Fortran-specific
#                           -fno-protect-parens and -fstack-arrays.
