These three patches add support for -mcpu=power11 to the PowerPC GCC compiler.
There are 3 patches in the set. I would like to check these patches into GCC
15 ASAP, and back port the patches into GCC 14 after GCC 14.1 ships. I hope to
also back port these patches to other active branches after the code goes into
GCC 15 and then GCC 14.
Patch #1: This patch adds the basic support for power11.
* This patch adds the -mcpu=power11.
* This patch adds a power11 processor type.
* This patch adds a bit to the isa_flags for power11 support.
* This patch defines _ARCH_PWR11 if -mcpu=power11 is used.
* This patch uses .machine power11 if -mcpu=power11 is used.
* This patch passes -mpower11 or -mpwr11 to the assembler.
* This patch uses the power10 defaults for power11.
* This patch adds AUXV support for power11.
Patch #2: This patch adds tuning support for power11, treating power11 like
power10 at the current time.
Patch #3: This patch adds tests that are run if the assembler supports either
-mpower11 (under Linux) or -mpwr11 (under AIX).
These patches have been tested with bootstrap builds on a little endian power10
and a big endian power9 system. When the GCC 15 tree opens up for general
patches, can I apply this patch?
