* Makefile.in (SIM_OBJS): Add dsp.o.
(dsp.o): New dependency.
(IGEN_INCLUDE): Add dsp.igen.
* configure.ac (mipsisa32r2*-*-*, mipsisa32*-*-*, mipsisa64r2*-*-*,
mipsisa64*-*-*): Add dsp to sim_igen_machine.
* configure: Regenerate.
* mips.igen: Add dsp model and include dsp.igen.
(MFHI, MFLO, MTHI, MTLO): Remove mips32, mips32r2, mips64, mips64r2,
because these instructions are extended in DSP ASE.
* sim-main.h (LAST_EMBED_REGNUM): Change from 89 to 96 because of
adding 6 DSP accumulator registers and 1 DSP control register.
