+==================== Branch work165, patch #11 ====================
+
+Add -mcpu=future tuning support.
+
+This patch makes -mtune=future use the same tuning decision as -mtune=power11.
+
+2024-04-08  Michael Meissner  <meissner@linux.ibm.com>
+
+gcc/
+
+	* config/rs6000/power10.md (all reservations): Add future as an
+	alterntive to power10 and power11.
+
+==================== Branch work165, patch #10 ====================
+
+Add -mcpu=future support.
+
+This patch adds the future option to the -mcpu= and -mtune= switches.
+
+This patch treats the future like a power11 in terms of costs and reassociation
+width.
+
+This patch issues a ".machine future" to the assembly file if you use
+-mcpu=power11.
+
+This patch defines _ARCH_PWR_FUTURE if the user uses -mcpu=future.
+
+This patch allows GCC to be configured with the --with-cpu=future and
+--with-tune=future options.
+
+This patch passes -mfuture to the assembler if the user uses -mcpu=future.
