It's completely thread-package-agnostic. I dump all LWPs sharing the same VM, as a fairly reliable marker (I'd use 2.4 threadgroups, but LinuxThreads doesn't use them...) So there is enough information there for lin-lwp to parse the threads, if we stubbed out its attempts to write, I expect. But since the current Linux threads model has one thread per process, I can simply use the corefile.c thread support instead, which I'd rather do. -- Daniel Jacobowitz Carnegie Mellon University MontaVista Software Debian GNU/Linux Developer
