O-MVLL (in reference to O-LLVM) is a LLVM-based obfuscator driven by Python and the LLVM pass manager. It can be run as follows:

clang++ -fpass-plugin=libOMVLL.dylib main.cpp -o main

import omvll
class MyConfig(omvll.ObfuscationConfig):
 def __init__(self):
 super().__init__()
 def flatten_cfg(self, mod: omvll.Module, func: omvll.Function):
 if func.name == "check_password":
 return True
 return False

O-MVLL Pipeline

O-MVLL can be used with the Android NDK and an iOS toolchain. It currently supports AArch64 and ARM architectures.
