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/build.rs | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 plugins/workflow_objc/build.rs (limited to 'plugins/workflow_objc/build.rs') diff --git a/plugins/workflow_objc/build.rs b/plugins/workflow_objc/build.rs new file mode 100644 index 00000000..ed6cec7d --- /dev/null +++ b/plugins/workflow_objc/build.rs @@ -0,0 +1,15 @@ +fn main() { + let link_path = std::env::var_os("DEP_BINARYNINJACORE_PATH") + .expect("DEP_BINARYNINJACORE_PATH not specified"); + + println!("cargo::rustc-link-lib=dylib=binaryninjacore"); + println!("cargo::rustc-link-search={}", link_path.to_str().unwrap()); + + #[cfg(not(target_os = "windows"))] + { + println!( + "cargo::rustc-link-arg=-Wl,-rpath,{0},-L{0}", + link_path.to_string_lossy() + ); + } +} -- cgit v1.3.1
