-dnl variables: ${sim_mips_multi_configs} and ${sim_mips_multi_default}.
-dnl
-dnl ${sim_mips_multi_configs} is the list of engines to build. Each
-dnl space-separated entry has the form NAME:MACHINE:FILTER:BFDMACHS,

-dnl
-dnl - NAME is a C-compatible prefix for the engine,
-dnl - MACHINE is a -M argument,
-dnl - FILTER is a -F argument, and
-dnl - BFDMACHS is a comma-separated list of bfd machines that the
-dnl simulator can run.
-dnl
-dnl Each entry will have a separate simulation engine whose prefix is
-dnl m32<NAME>. If the machine list includes "mips16", there will also
-dnl be a mips16 engine, prefix m16<NAME>. The mips16 engine will be

-dnl but the filter will be "16" instead of FILTER.
-dnl
-dnl The simulator compares the bfd mach against BFDMACHS to decide
-dnl which engine to use. Entries in BFDMACHS should be bfd_mach
-dnl values with "bfd_mach_" removed. ${sim_mips_multi_default} says

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