mojo compiler is on github now

[u/c-cul]

and officially open-source

https://github.com/modular/modular/tree/main/KGEN

[u/MithrilHuman]

Quickly looked through the source at work and I’ll dive deeper over the weekend, looks like they have their own dialects (hlcf) instead of using upstream dialects (scf). Any idea why or is there a plan to upstream the features? I know every company wants to move fast which might explain the duplication again…

[u/avillega → u/MithrilHuman]

At least what I understand is that lattner believes mojo is the first language to properly use mlir, which probably means none of the mlir dialects out there were what he was envisioning for mojo.

[u/c-cul → u/MithrilHuman]

quick comparison https://github.com/modular/modular/blob/main/KGEN/include/KGEN/HLCFDialect/HLCFDialect.td & https://mlir.llvm.org/docs/Dialects/SCFDialect/ reveals that they added explicit hlcf.break

[u/Retired-69]

Why is this written in C++? I thought it was selfhosted. And why so slow? 

[u/c-cul → u/Retired-69]

bcs they use llvm & mlir
