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 | |
25 | # reasons). | |
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. | |
32 | # | |
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. | |
