[patch] Simulator support for MIPS32 DSP ASE

["Chao-ying Fu" <fu at mips dot com>]

Hello,

  Here is the sim patch for MIPS32 DSP ASE.  The patch includes
the simulator support and new tests for DSP instructions.  I test with
two configurations.  No new regressions.

1.
Test Run By fu on Mon Aug  8 14:11:50 2005
Target is mipsisa32-unknown-elf
Host   is i686-pc-linux-gnu
                === sim tests ===
Schedule of variations:
    mips-sim
                === sim Summary ===
# of expected passes            22

  Could any maintainers review the patch?  Thanks a lot!

2005-08-08  Chao-ying Fu  <fu@mips.com>

    * 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.
    (AC0LOIDX, AC0HIIDX, AC1LOIDX, AC1HIIDX, AC2LOIDX, AC2HIIDX, AC3LOIDX,
    AC3HIIDX, DSPLO, DSPHI, DSPCRIDX, DSPCR, DSPCR_POS_SHIFT,
    DSPCR_POS_MASK, DSPCR_POS_SMASK, DSPCR_SCOUNT_SHIFT, DSPCR_SCOUNT_MASK,

    DSPCR_OUFLAG7, DSPCR_CCOND_SHIFT, DSPCR_CCOND_MASK,
    DSPCR_CCOND_SMASK): New define.
    (DSPLO_REGNUM, DSPHI_REGNUM): New array for DSP accumulators.
    * dsp.c, dsp.igen: New files for MIPS DSP ASE.
