raptorlake mistaken for alderlake

[frnzhop]

Hi,

on my machine (intel 13th gen "raptorlake"), this program reports -march=alderlake instead of -march=raptorlake:

$ resolve-march-native
-march=alderlake -mabm -mno-cldemote -mno-kl -mno-sgx -mno-widekl -mshstk --param=l1-cache-line-size=64 --param=l1-cache-size=32 --param=l2-cache-size=36864

Hi @20mattia02, how is that a bug in resolve-march-native? I would expect that either it's a bug in GCC or no bug at all. What do you think?

Closing as "not a bug in resolve-march-native"…
