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.
