how to add "hardened_malloc" memory allocator support to emscripten for WASM? https://www.google.com/search?q=how+to+add+%22hardened_mallo...

Just learned about Cage:

Cage does Hardware-Accelerated Safe WebAssembly (WASM) with LLVM with support for ARM64 Memory Tagging Extension (MTE) and Pointer Authentication (PAC) memory safety features.
