commit 0c2202c179ca98d5212bc5a0488a52040f100c11
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Feb 29 12:53:22 2024 -0500
Add -mcpu=power11 support.
This patch adds support for -mcpu=power11. At the current time, no new
instructions are implemented. The tuning for the power11 processor is exactly
the same as for power10.
If -mcpu=power11 is used, the macro _ARCH_PWR11 will be defined.
In order to use -mcpu=power11, you will need an assembler that supports the
-mpower11 option.

commit b174e1813f6fdca4237f49dca25ce35b3a447767
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Feb 29 12:47:53 2024 -0500
Add -mcpu=power11 support.
This patch adds support for -mcpu=power11. At the current time, no new
instructions are implemented. The tuning for the power11 processor is exactly
the same as for power10.
If -mcpu=power11 is used, the macro _ARCH_PWR11 will be defined.
In order to use -mcpu=power11, you will need an assembler that supports the
-mpower11 option.

commit 3bf2b9ada3cf0bcdab1ce9779ddb1a9ad078908c
Author: Michael Meissner <meissner@linux.ibm.com>
Date: Thu Feb 29 01:46:00 2024 -0500
Add -mcpu=power11 support.
This patch adds support for -mcpu=power11. At the current time, no new
instructions are implemented. The tuning for the power11 processor is exactly
the same as for power10.
If -mcpu=power11 is used, the macro _ARCH_PWR11 will be defined.
In order to use -mcpu=power11, you will need an assembler that supports the
-mpower11 option.
2024-02-29 Michael Meissner <meissner@linux.ibm.com>
