Hello,
Per the announcement from gcc, `-march=neoverse-v2’ is a new target available with gcc-13:
A number of new CPUs are supported through the -mcpu and -mtune options
- Ampere-1A (ampere1a).
- Arm Cortex-A715 (cortex-a715).
- Arm Cortex-X1C (cortex-x1c).
- Arm Cortex-X3 (cortex-x3).
- Arm Neoverse V2 (neoverse-v2).
https://gcc.gnu.org/gcc-13/changes.html
Rocky 9.3 is shipped with v11.4.1
$ gcc --version
gcc (GCC) 11.4.1 20231218 (Red Hat 11.4.1-3)
However, I noticed that this version of gcc did support neoverse-v2 target:
$ gcc -mcpu=neoverse-v2 -E -dM - < /dev/null | grep __ARM

Does this imply that the support for neoverse-v2 has been backported to Rocky 9.3 ?
Thanks.
