I'm sending this patch out for comments. It adds the capability to get strace(1) like output from the target executable in user-linux mode. A couple of things that should probably be done before calling it done is to fill in more call specific format strings, and using a technique similar to how the format strings are handled, add the ability to have syscall specific output functions that could decode flags, etc to give more detailed output. Any feedback would be appreciated. Stuart Stuart R.
