Missing host id Cortex-A78AE

[sjoerdmeijer]

Cortex-A78AE does not have an host id in llvm/lib/TargetParser/Host.cpp:

   ...
    .Case("0xd0d", "cortex-a77")
    .Case("0xd41", "cortex-a78")
    .Case("0xd47", "cortex-a710")
    .Case("0xd4d", "cortex-a715")
    ...

As a result -mpcu=native doesn't work.

@jthackray too, who might be interested.

I'm not sure if this is upstream yet. It would be good to make sure we add host.cpp support when we do.

[jthackray]

Agreed. I'll have a look.

Ah sorry, I now indeed see that there is no -mcpu=cortex-a78ae support upstream yet. I was assuming that was already in place. Anyway, thanks for taking a look!

[sjoerdmeijer]

And please feel free to close this issue if this is going to be part of your upstreaming effort.
