It's still not clear to me what it means to "follow" syscalls for :2. Is that copying the syscall watchlist to the child? >> have thought we just needed to add fork-events+ and vfork-events+ to our >> qSupported string. > Hmm yea, so add fork-events+ and vfork-events+ and just make following clones > the default? Well, these can still be dependent on the presence of -f, but yeah. > a list of syscalls would be $QCatchSyscalls:1;0;1;2;3;4;5;6;7;8;9; > all syscalls would be $QCatchSyscalls:1 > > That seems reasonable to me. Great - if that works, I think it's better since nothing has to change in the gdbserver protocol. >> PS- on git procedure ...
