Support for PowerPC

[bbartoldson]

Please consider adding support for Power9 (e.g.) computers. Thanks!

You can build LLVM from scratch and build triton, right?

have you figured it out ? @Jokeren can u explain more detail how to do that. Thank you

i have done the llvm build as stated in the root/readme.md. still there was an error.

have you figured it out ? @Jokeren can u explain more detail how to do that. Thank you.

Hey @NavinKumarMNK I left a detailed comment on #3448 on how to resolve that issue and how to potentially overall enable PowerPC architecture in Triton repo. That should also address the error you refer to in the last comment.

@Jokeren Building Triton doesn't work as-is out of the box today for PowerPC hardware architecture. It would be a similar lift to what was done to add aarch64/arm64 support for building Triton from source. I believe support for building LLVM from source for PPC64 targets already exists in that project. But I don't have first hand experience with it.
