Re: [patch ping2] Simulator Supports for MIPS32 DSP ASE

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

Hi,

  Here is the revised patch for MIPS32 DSP ASE.  We changed
the copyright to FSF for our new files.  Tested with two
configurations.  No new regressions.  Is it ok to commit?  Thanks!

Regards,
Chao-ying

1. --target=mipsisa32-elf
Test Run By fu on Tue Oct 11 14:02:10 2005
Target is mipsisa32-unknown-elf
Host   is i686-pc-linux-gnu
                === sim Summary ===
# of expected passes            22

2. --target=mipsisa64-elf
Test Run By fu on Tue Oct 11 14:23:31 2005
Target is mipsisa64-unknown-elf
Host   is i686-pc-linux-gnu
                === sim Summary ===
# of expected passes            45
# of unexpected failures        1

sim/mips/ChangeLog
2005-10-11  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_SCOUNT_SMASK, DSPCR_CARRY_SHIFT, DSPCR_CARRY_MASK,
    DSPCR_CARRY_SMASK, DSPCR_CARRY, DSPCR_EFI_SHIFT, DSPCR_EFI_MASK,
    DSPCR_EFI_SMASK, DSPCR_EFI, DSPCR_OUFLAG_SHIFT, DSPCR_OUFLAG_MASK,
    DSPCR_OUFLAG_SMASK, DSPCR_OUFLAG4, DSPCR_OUFLAG5, DSPCR_OUFLAG6,
    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.
