torch-mlir/include/npcomp/RefBackend/Runtime

Refbackrt (namespace refbackrt) is the runtime support library for the RefBackend backend. It is best practice to keep compiler and runtime code totally firewalled.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! As such, this directory should have NO DEPENDENCIES ON COMPILER CODE (no LLVM libSupport, etc.). !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This will cause some duplication, but history has shown that this firewalling pays big dividends. In particular, compiler code very frequently has binary sizes that are simply unacceptable in runtime scenarios, such as MByte-sized dependencies like LLVM libSupport. Runtime code should fit in kBytes.
