# Nordic Softdevice SDK header files contains inline assembler that has
# broken constraints. As a result the IPA-modref pass, introduced in gcc-11,
# is able to "prove" that arguments to wrapper functions generated with
# the SVCALL() macro are unused and, as a result, the optimizer will remove
# code within the callers that sets up these arguments (which results in
# a broken bootloader). The broken headers come from Nordic-supplied zip
# files and are not trivial to patch so, for now, we'll simply disable the
# new gcc-11 inter-procedural optimizations.
