22 # Special flags for fault_64.o.  This puts restrictions on the number of
23 # caller-save registers that the compiler can target when building this file.
24 # This is required because the code is called from a context in entry.S where
25 # very few registers have been saved in the exception handler (for speed
26 # reasons).
27 # The caller save registers that have been saved and which can be used are
28 # r2,r3,r4,r5 : argument passing
29 # r15, r18 : SP and LINK
30 # tr0-4 : allow all caller-save TR's.  The compiler seems to be able to make
31 #         use of them, so it's probably beneficial to performance to save them
32 #         and have them available for it.
33 #
34 # The resources not listed below are callee save, i.e. the compiler is free to
35 # use any of them and will spill them to the stack itself.
