loongson2f support:
- Add some loongson2 definitions to cpuregs.h, from OpenBSD
- Make sure that the at register is useable before every jump register
instruction (exept when register is k0 or k1)
loongson2f support:
- Add some loongson2 definitions to cpuregs.h, from OpenBSD
- Make sure that the at register is useable before every jump register
instruction (exept when register is k0 or k1) because -mfix-loongson2f-btb
needs the at register for its workaround
- add code to mips_fixup.c to handle the instructions added by
-mfix-loongson2f-btb
- Add a ls2-specific tlb miss handler: it doesn't have separate handler
for the xtlbmiss exeption.
- Fixes for some #ifdef MIPS3_LOONGSON2 assembly code (using the wrong
register)
