mips.c (mips_use_dfa_pipeline_interface): Delete.
* config/mips/mips.c (mips_use_dfa_pipeline_interface): Delete.
(TARGET_SCHED_USE_DFA_PIPELINE_INTERFACE): Define to hook_int_void_1.
* config/mips/3000.md: Add copyright notice. Remove automota and
function units; use generic ones instead. Only define reservations
for things that are different from generic.md. Extend each clause
to include r3900.
* config/mips/{4000,4100,4300,4600,5000,6000,generic}.md: New files.
* config/mips/mips.md: Include them. Remove define_function_units.
(alu, imuldiv): New automata and units.
