5.7.7.22 Keep-inline-functions Option
The -fkeep-inline-functions option ensures that separate run-time-callable
assembly code for functions is output, even if all calls to a given function are inlined
and the function is declared static. This switch does not affect the
output of extern inline functions.
The -fno-keep-inline-functions form of this option will not emit output
for static functions where all calls to it have been inlined. This is
the default action if no option has been specified.
