commit e3ea7f0f88776cdf93f5a0a8da4276a6e5c6b197
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Sep 28 14:09:30 2023 -0400
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.

commit 8a3aa22b1cc796318d0c614b7db45e0995273e08
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Sep 28 14:09:30 2023 -0400
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.
