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