-==================== Branch work174, patch #34 ====================
-
-Do not allow -mvsx to boost processor to power7.
-
-This patch restructures the code so that -mvsx for example will not silently
-convert the processor to power7. The user must now use -mcpu=power7 or higher.
-This means if the user does -mvsx and the default processor does not have VSX
-support, it will be an error.

-
-==================== Branch work174, patch #33 ====================
-
-Use architecture flags for defining _ARCH_PWR macros.
-
-For the newer architectures, this patch changes GCC to define the _ARCH_PWR<n>
-macros using the new architecture flags instead of relying on isa options like
--mpower10.
-
-The -mpower8-internal, -mpower10, and -mpower11 options were removed. The
--mpower11 option was removed completely, since it was just added in GCC 15.
The
-other two options were marked as WarnRemoved, and the various ISA bits were
-removed.
-
-TARGET_POWER8 and TARGET_POWER10 were re-defined to use the architeture bits
-instead of the ISA bits.
-
-There are other internal isa bits that aren't removed with this patch because
-the built-in function support uses those bits.

-==================== Branch work174, patch #32 ====================
-
-Set .machine from the architecture flags
-
-This patch switches the handling of .machine to use architecture masks if they
-exist (power4 through power11). All of the other PowerPCs will continue to use
-the existing code for setting the .machine option.

-
-Make clone_targets use architecture flags.
-
-This patch expands on the previous patch and changes the target_clones support
-to use an architecture mask instead of isa bits.

-
-==================== Branch work174, patch #30 ====================
-
-Add rs6000 architecture masks.
-
-This patch begins the journey to move architecture bits that are not user ISA
-options from rs6000_isa_flags to a new targt variable rs6000_arch_flags. The
-intention is to remove switches that are currently isa options, but the user
-should not be using this particular option. For example, we want users to use
--mcpu=power10 and not just -mpower10.

- 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. */
