From 2303f75b080f6dd0c9a5c669a71f64ce830f5650 Mon Sep 17 00:00:00 2001 From: Mark Rowe Date: Mon, 11 Aug 2025 10:42:07 -0700 Subject: Rewrite Obj-C workflow in Rust This is functionally equivalent to the previous workflow_objc, with the following changes: 1. It mutates the `core.function.metaAnalysis` workflow rather than registering a new named workflow. The activities now all check for the presence of the Objective-C metadata added by `ObjCProcessor` to determine whether they should do work, rather than relying on `MachoView` to override the function workflow when Objective-C metadata is present. This fixes https://github.com/Vector35/binaryninja-api/issues/6779. 2. The auto-inlining of `objc_msgSend` selector stub functions is performed in a separate activity from the processing of `objc_msgSend` call sites. The selector stub inlining activity is configured so that it does not run in `DSCView` as the shared cache needs different behavior for stub functions more generally that `SharedCacheWorkflow` already provides. 3. The way that types like `id` and `SEL` are referenced is fixed so that they show up as `id` rather than `objc_struct*`. This also replaces the Objective-C portion of the shared cache's workflow, and incorporates several bug fixes that had been applied to it but not the standalone Objective-C workflow. --- plugins/workflow_objc/MessageHandler.h | 16 ---------------- 1 file changed, 16 deletions(-) delete mode 100644 plugins/workflow_objc/MessageHandler.h (limited to 'plugins/workflow_objc/MessageHandler.h') diff --git a/plugins/workflow_objc/MessageHandler.h b/plugins/workflow_objc/MessageHandler.h deleted file mode 100644 index 8826b094..00000000 --- a/plugins/workflow_objc/MessageHandler.h +++ /dev/null @@ -1,16 +0,0 @@ -#pragma once - -#include - -class MessageHandler { - - std::set m_msgSendFunctions; - static std::set findMsgSendFunctions(BinaryNinja::Ref data); - -public: - MessageHandler(BinaryNinja::Ref data); - - std::set getMessageSendFunctions() const { return m_msgSendFunctions; } - bool hasMessageSendFunctions() const { return m_msgSendFunctions.size() != 0; } - bool isMessageSend(uint64_t); -}; -- cgit v1.3.1
