old-cross-binutils/sim/mips/configure.ac
Chao-ying Fu 40a5538e94 * 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.

# The MULTI generator can combine several simulation engines into one.
# executable. A configuration which uses the MULTI should set two
# variables: ${sim_multi_configs} and ${sim_multi_default}.
#
# ${sim_multi_configs} is the list of engines to build. Each
# space-separated entry has the form NAME:MACHINE:FILTER:BFDMACHS,
# where:
#
# - NAME is a C-compatible prefix for the engine,
# - MACHINE is a -M argument,
# - FILTER is a -F argument, and
# - BFDMACHS is a comma-separated list of bfd machines that the
# simulator can run.
#
# Each entry will have a separate simulation engine whose prefix is
# m32<NAME>. If the machine list includes "mips16", there will also
# be a mips16 engine, prefix m16<NAME>. The mips16 engine will be
# generated using the same machine list as the 32-bit version,
# but the filter will be "16" instead of FILTER.
#
# The simulator compares the bfd mach against BFDMACHS to decide
# which engine to use. Entries in BFDMACHS should be bfd_mach
# values with "bfd_mach_" removed. ${sim_multi_default} says
# which entry should be the default.
