* doc/md.texi (madd@var{m}@var{n}4, umadd@var{m}@var{n}4): Document.
* optabs.h (OTI_smadd_widen, OTI_umadd_widen): New optab_indexes.
(smadd_widen_optab, umadd_widen_optab): Define.
* optabs.c (init_optabs): Initialize smadd_widen_optab and
umadd_widen_optab.
* genopinit.c (optabs): Fill in smadd_widen_optab and
umadd_widen_optab.
* expr.c (expand_expr_real_1): Try to use smadd_widen_optab
and umadd_widen_optab to implement multiply-add sequences.
* config/mips/mips.md (*<su>mul_acc_di): Rename to...
(<u>maddsidi4): ...this. Extend condition to include
GENERATE_MADD_MSUB and TARGET_DSPR2. Change the constraint
of operand 0 to "ka" and use the three-operand form of madd<u>
for TARGET_DSPR2.
* config/mips/mips-dspr2.md (mips_madd, mips_maddu): Convert
to define_expands.
* config/mips/constraints.md (ka): New register constraint.
