> Is there an rr-like reverse time-travel debugging tool for ARM64/aarch64? Aside from `khuey`'s comment (https://news.ycombinator.com/item?id=30779913 https://news.ycombinator.com/item?id=30779913) that `rr` can now work on ARM64, we at Undo (https://undo.io https://undo.io) have an ARM64 port under routine internal testing as we expect it to be important in the future. GDB's built-in record/replay is also supposed to work on ARM64 - https://sourceware.org/gdb/onlinedocs/gdb/Process-Record-and-Replay.html https://sourceware.org/gdb/onlinedocs/gdb/Process-Record-and... Last I heard, on x86, the performance and memory overheads of that implementation were quite high but if it solves your problem maybe that's fine!
