2# don't work universally, there are recipes which can't use one, the other
3# or both so a blacklist is maintained here. The idea would be over
4# time to reduce this list to nothing.
5# From a Yocto Project perspective, this file is included and tested
6# in the DISTRO="poky-lsb" configuration.

8# _FORTIFY_SOURCE requires -O1 or higher, so disable in debug builds as they use
9# -O0 which then results in a compiler warning.
