From 26255186e2e94e0fe62cfd0965662494b6aab27c Mon Sep 17 00:00:00 2001 From: David Wood Date: Mon, 17 Oct 2022 14:11:26 +0100 Subject: [PATCH] various: translation resources from cg backend Extend `CodegenBackend` trait with a function returning the translation resources from the codegen backend, which can be added to the complete list of resources provided to the emitter.
