Next steps
MS: I've managed to compile and run SQLite, redis and nginx with gcc-12 on AArch64.
MS: I've managed to compile SQLite, redis and nginx with clang on AArch64.
MS: Only SQLite is running normally, I'm still investigating redis's and nginx's behaviour.
MS: I'm unable to run any of these apps with Shadow Stack support.
VB: That's because these apps use multithreading.
VB: Every thread has its own stack, consequently, it should also have its own Shadow Stack, for which, right now, there is no support.
VB: You should consider leaving porting clang for complex apps in the background, focus on bringing support for the multithreading friendly Shadow Stack.
VB: Before starting implementing, use gdb to investigate a simple program, with 2-3 threads.
MS: Use gdb to investigate a simple program, with 2-3 threads.
MS: Start implementing the Shadow Stack for multithreading programs.
MS: If necessary ask Michalis and Simon about performance issues.
MS: If time allows it, continue to work on porting clang for redis and nginx and testing app-lua and app-python3.
VB: Further investigate Android optimizations
