I'm attempting to use ptrace to manipulate registers on aarch64. Looking at sys/user.h in my aarch64 toolchain (android-ndk-r10e), I see
#elif defined(__aarch64__)
// There are no user structures for 64 bit arm.
#else
Perhaps I'm missing something obvious but how do I get/set registers for an aarch64 program?
struct user_pt_regs is defined in asm/ptrace.h which is (eventually) included by sys/ptrace.h.
