+==================== Branch work139-dmf, patch #100 ====================
+
+PowerPC: Add -mcpu=future.
+
+These patches implement support for potential future PowerPC cpus.  At this
+time, features enabled with -mcpu=future may or may not be in actual PowerPCs
+that will be delivered in the future.
+
+This patch adds support for the -mcpu=future and -mtune=future options.
+If you use -mcpu=future, the macro __ARCH_PWR_FUTURE__ is defined, and the
+assembler .machine directive "future" is used.  Future patches in this
+series will add support for new instructions that may be present in future
+PowerPC processors.
+
+At the moment, we do not have any differences in tuning between power10 and
+future.  It is anticipated that we may change the tuning characteristics for
+-mtune=future at a later time.
+
+The patches have been tested on the following platforms.  I added the patches
+for PR target/107299 that I submitted on November 2nd before doing the builds so
+that GCC would build on systems using IEEE 128-bit long double.
