  40 # Special flags for fault_64.o.  This puts restrictions on the number of
  41 # caller-save registers that the compiler can target when building this file.
  42 # This is required because the code is called from a context in entry.S where
  43 # very few registers have been saved in the exception handler (for speed
  44 # reasons).
  45 # The caller save registers that have been saved and which can be used are
  46 # r2,r3,r4,r5 : argument passing
  47 # r15, r18 : SP and LINK
  48 # tr0-4 : allow all caller-save TR's.  The compiler seems to be able to make
  49 #         use of them, so it's probably beneficial to performance to save them
  50 #         and have them available for it.
  51 #
  52 # The resources not listed below are callee save, i.e. the compiler is free to
  53 # use any of them and will spill them to the stack itself.
