| # 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. | |
