  24 #       This Makefiles contains the common targets and definitions for
  25 #       all kernels. It is to be included in the Makefiles for specific
  26 #       implementation architectures and processor architecture dependent
  27 #       modules: i.e.: all driving kernel Makefiles.

  37 #       All C objects depend on inline files. However, cc(1) doesn't generate
  38 #       the correct dependency info. Also, these Makefiles don't contain a
  39 #       separate list of C-derived object files (but it is light weight to
  40 #       let the assembler files think they depend upon this when they don't).
  41 #       Fortunately, the inline files won't change very often. So, for now,
  42 #       all objects depend on the inline files. Remove this when the inliner
  43 #       is fixed to drop correct dependency information.
