Meta says it has upstreamed most of a shared debugging framework to LLVM that lets developers inspect CPU and GPU code in one LLDB session. The framework separates common debugger functions from plugins that handle each hardware vendor's devices.

It represents CPUs and GPUs as separate debugger processes, preserving their different instruction sets and memory spaces while coordinating breakpoints and execution. The framework supports live debugging and inspection of GPU crash dumps. Vendor integrations and some common infrastructure remain unfinished; GPU support activates only when an application uses a supported runtime.
