    Phoronix: Zhaoxin Tries Again To Upstream Their "LuJiaZui" CPU Support Within GCC

    Back in 2019 Chinese CPU company Zhaoxin introduced "LuJiaZui" as their 16nm x86 CPU design for use from laptops up through servers. LuJiaZui is much improved from their earlier chips though still well behind AMD and Intel performance. Proper GCC compiler support for LuJiaZui was sent out again this week after their previous upstreaming attempt hadn't made it into GCC 12 due to being late in the cycle...

    While I would love to get my hands on the Chinese x64 processors, this patch seems to only enable the ability to build with -march=native, which has zero purpose since people should be building with -march=x86-64 for portability.

      Depends. If you need max. performance for a specific program... Or Gentoo users, some use generic flags, some are certain about what they're doing and simply use the best flags for the current machine.

      Not that any of these CPUs has been available outside Asian regions yet... at least I haven't seen any of them.
      Stop TCPA, stupid software patents and corrupt politicians!

        You can get them on Taobao but they're extremely expensive relative to their performance.

          Sounds just like hardware you'd get from e.g. Oracle.
