-==================== Branch work175, patch #11 ====================
+==================== Branch work175, patch #21 ====================
Add -mcpu=future tuning support.
This patch makes -mtune=future use the same tuning decision as -mtune=power11.

* config/rs6000/power10.md (all reservations): Add future as an
alterntive to power10 and power11.
-==================== Branch work175, patch #10 ====================
+==================== Branch work175, patch #20 ====================
-Add -mcpu=future support.
+Add support for -mcpu=future
-This patch adds the future option to the -mcpu= and -mtune= switches.
+This patch adds the support that can be used in developing GCC support for
+future PowerPC processors.
-This patch treats the future like a power11 in terms of costs and reassociation
-width.
+2024-08-02 Michael Meissner <meiss...@linux.ibm.com>
-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.
