-`ptrace` has some issues (`sysdeps/mach/hurd/ptrace.c`).
-
- * Our implementation (and the generic one in `misc/ptrace.c`) differ
- from the Linux one (`sysdeps/unix/sysv/linux/ptrace.c`)
- w.r.t. handling of...
-
- * the third argument: `int data` vs. `void *data`;
-
- * `void *addr2` -- Linux doesn't have this, but we provide some
- additional functionalty using this;
-
- * function declaration: Linux has **`long`** `int ptrace (enum
- __ptrace_request __request, ...)` **`__THROW`**, we have `int ptrace
- (enum __ptrace_request __request, ...)`;
-
- * interface do differ, e.g., Linux' `PTRACE_GETREGS` uses `void
- *data`, we use `void *addr` for returning the struct, and in
- Linux this is a `struct user_regs_struct` from `linux/user.h`,
- and for us it is a `struct i386_thread_state` from
- `mach/i386/thread_status.h`;
-
- * Linux provides some functionality that we don't provide:
- `PTRACE_GETFPXREGS` , `PTRACE_SINGLESTEP`.
-
- * Some parts are wrongly implemented, e.g., `PTRACE_GETREGS` and
- `PTRACE_SETREGS` both do the same thing.
-
-Also consider the `sysdeps/generic/sys/ptrace.h` and
-`sysdeps/unix/sysv/linux/sys/ptrace.h` files.
