…ternal codegen paths (See https://discuss.tvm.apache.org/t/byoc-supporting-cutlass-byoc-with-collage/12796/6 for context, which in turn is part of Collage (https://github.com/apache/tvm-rfcs/blob/main/rfcs/0062-collage.md). We want both old-style (via relay.ext.$toolchain) and new-style (via "RelayToTIR" Pass attribute on target kind) external codegen to be able to access the current 'external codegen' Target instance via Target.current(). - For old-style, plumb the true Target through TEComplier and push it on the context stack before calling relay.ext.$toolchain. - For new-style, pass the CompilationConfig to the RelayToTIRTargetHook pass, make the jump from "Compiler" attribute value to Target via the new CompilationConfig::FindPrimitiveTargetForKind method, and push on the stack before invoking the custom "RelayToTIR" pass. While working on this discovered RelayToTIRTargetHook was incompatible with the VM's compilation flow since RelayToTIRTargetHook assumes all "Compiler" attributed functions are inlined. Generalize it to support both inline and global function styles. Extend Target::IsExternalCodegen to recognize target kinds with "RelayToTIR" attributes as external. Update target hooks unit test to exercise new support for outline-style, picking up the current target, and compiling via the VM. -- This is an automated message from the Apache Git Service.
