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.
