KittyMemory
Dedicated library for runtime code patching & some memory utilities for both Android and iOS.
KittyMemory now depends on Keystone Assembler for MemoryPatch::createWithAsm.
Prebuilt Keystone binaries are already included Here, However if you want to build them yourself you can use the scripts build-android.sh & build-ios.sh.
If for any reason you don't want to use Keystone and MemoryPatch::createWithAsm then add definition kNO_KEYSTONE to your project cpp flags.
Check Android example & iOS example for how to use & build.
