crti.asm: Add changes for mips16.
2002-02-05 Eric Christopher <echristo@redhat.com>
* config/mips/crti.asm: Add changes for mips16. mips16 uses
register 7 as RA instead of $31.
* config/mips/crtn.asm: Ditto.
* config/mips/mips.c (mips_move_2words): Add case for
TARGET_MIPS16 when HOST_BITS_PER_WIDE_INT >= 64.
(compute_frame_size): Fix typo.
(save_restore_insns): Ditto. Make documentation about using
register $7 as return register more precise.
(mips_expand_epilogue): Fix comment. Add code to work around not
being able to add to the stack pointer directly.
* config/mips/mips.h (EH_RETURN_DATA_REGNO): Change register number
to 2 for TARGET_MIPS16 as we need 6 and 7 as clobbers in the
epilogue.
