* config/mmix/mmix.h (MMIX_LAST_STACK_REGISTER_REGNUM): Renamed
from MMIX_LAST_REGISTER_FILE_REGNUM.
(NO_IMPLICIT_EXTERN_C): Remove cryptic obsolete comment.
(struct machine_function): New member highest_saved_stack_register
previously static variable in mmix.c.
(MACHINE_DEPENDENT_REORG): Define.
* config/mmix/mmix.c (highest_saved_stack_register): Deleted.
(MMIX_OUTPUT_REGNO): New.
(mmix_target_asm_function_prologue): Move calculation of last used
saved-stack-register into...
(mmix_machine_dependent_reorg): New function. Update to also handle
!TARGET_ABI_GNU.
(mmix_print_operand): Apply MMIX_OUTPUT_REGNO when emitting
register names, simplify somewhat by new variable regno.
<case 'p'>: Remove fixed FIXME. Always emit highest used saved
register.
(mmix_print_operand_address): Apply MMIX_OUTPUT_REGNO when
emitting register names.
(mmix_asm_output_reg_push, mmix_asm_output_reg_pop): Ditto.
(mmix_dbx_register_number): Apply MMIX_OUTPUT_REGNO here too.
Remove fixed FIXME.
* config/mmix/mmix-protos.h (mmix_machine_dependent_reorg):
Declare.
* config/mmix/mmix.md ("divmoddi4"): Update head comment.
