# 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.
