-/* This file defines architecture features that are based on the -mcpu=<proc>
- option, and not on user options that can be turned on or off. The intention
- is for newer processors (power7 and above) to not add new ISA bits for the
- particular processor, but add these bits. Otherwise we have to add a bunch
- of hidden options, just so we have the proper ISA bits.
-
- For example, in the past we added -mpower8-internal, so that on power8,
- power9, and power10 would inherit the option, but we had to mark the option
- generate a warning if the user actually used it. These options have been
- moved from the ISA flags to the arch flags.
-
- To use this, define the macro ARCH_EXPAND which takes 2 arguments. The
- first argument is the processor name in upper case, and the second argument
- is a text name for the processor.
-
- The function get_arch_flags when passed a processor index number will set up
- the appropriate architecture flags based on the actual processor
- enumeration. */
