Questions about GCC options of Yocto BSP MR3 for Alder Lake-P

[HFuji1]

I asked this questions on IPS#00810245, but they did not answer, instead suggesting that I ask it here.

My question is:

Why "-march=nehalem -mtune=generic" GCC options is used on Yocto BSP Alder Lake-P MR3 ?

Isn't "-march=alderlake -mtune=alderlake" more suitable?

Please tell me the reason they are still using the option for old architecture.

Isn't performance improved by specifying "-march=alderlake -mtune=alderlake"?
