  49 # Special flags for tlbex_64.o.  This puts restrictions on the number of
  50 # caller-save registers that the compiler can target when building this file.
  51 # This is required because the code is called from a context in entry.S where
  52 # very few registers have been saved in the exception handler (for speed
  53 # reasons).
  54 # The caller save registers that have been saved and which can be used are
  55 # r2,r3,r4,r5 : argument passing
  56 # r15, r18 : SP and LINK
  57 # tr0-4 : allow all caller-save TR's.  The compiler seems to be able to make
  58 #         use of them, so it's probably beneficial to performance to save them
  59 #         and have them available for it.
  60 #
  61 # The resources not listed below are callee save, i.e. the compiler is free to
  62 # use any of them and will spill them to the stack itself.
