Is it possible to use the release build dylibs to compile a substrate tweak? If so, would I have to patch with optool and which dylib would need patching?

Would this be possible to use with Theos to obfuscate some code? I discovered Hikari not long ago but arm64e support isn't added and don't have enough LLVM knowledge to rewrite the project myself.

As you can see in the image below the clang-9 failed when i run make in theos for the first time but if i run make again and again it works after the 2nd or the 3rd try

Here's Theos makefile and yes it's libBnzLLVMObfuscationHook as i compiled it with Bnz prefix

Here's the error

Any suggest ?

Using the steps listed below, I've attempted to build and inject this version of Hikari into an Xcode 11.7 Toolchain.
See the images below for reference: After completing all the steps I've listed, Hikari "works", but I'm unable to pass any of the command line arguments to clang.

I've done the following steps, I'm not sure where I made a mistake:

• Compile this repository from source
• Move libLLVMObfuscationHook.dylib, libLLVMObfuscationDeps.dylib, and libsubstitute.dylib it into an Xcode toolchain from 11.7
• Using a compiled version of insert_dylib I ran the following 2 commands from within the Xcode toolchain's usr/bin directory
• insert_dylib --inplace @executable_path/libLLVMObfuscationDeps.dylib clang & insert_dylib --inplace @executable_path/libLLVMObfuscationHook.dylib clang

I built the library in the environment below

• osx : Catalina 10.15.6
• xcode : 12.1
• Separate clang installation as libLLVMObfuscation is not built in clang 12 version (xcode 12.1 toolchain)
  clang version 10.0.1 (https://github.com/llvm/llvm-project.git ef32c611aa214dea855364efd7ba451ec5ec3f74)
  Target: x86_64-apple-darwin19.6.0
  Thread model: posix

The following error occurs after executing the libLLVMObfuscation test built with clang 10

Hey:
Regarding the Post LLVM9 support. You'll just have to edit how you initialize Legacy PMB.
Example:
Remove Hikari's Obfuscation.cpp, register passes as-is into LegacyPassManagerBuilder and instead of createSwitchPass() and run it, just add lowerswitch pass before the pass calling it into the pipeline.

For example, the old method was MPM.add(createObfuscationPass()), instead of that , you should write MPM.add(createLowerSwitchPass()); MPM.add(createFlatteningPass())
