   3 # Some files which need to go both into libc and libm have external
   4 # dependencies which need to be resolved differently for libc
   5 # vs. libm.  For example, inside libc, __libm_error_support needs to
   6 # resolve to HIDDEN_JUMPTARGET(__libm_error_support) whereas within
   7 # libm it always resolves to __libm_error_support.  Such files need to
   8 # be compiled twice.  Fortunately, math/Makefile already has logic to
   9 # support this: if a file starts with "s_", make will automatically
  10 # generate a matching file whose name starts with "m_" which simply
  11 # includes the corresponding "s_" file.
