Hi All,
The Parts Num field for the MIDR for Cortex-X4 is wrong. It's currently the
parts number for a Cortex-A720 (which does have the right number).
The correct number can be found in the Cortex-X4 Technical Reference Manual [1]
on page 382 in Issue Number 5.
[1] https://developer.arm.com/documentation/102484/latest/
Bootstrapped Regtested on aarch64-none-linux-gnu and no issues.
Ok for master? and backport to GCC-14?
Thanks,
Tamar
gcc/ChangeLog:
* config/aarch64/aarch64-cores.def (AARCH64_CORE): Fix cortex-x4 parts
num.
