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