Andy Wingo 7656f19446 rework vm tracing ... * libguile/vm-engine.c (VM_NAME): Engines take the VM itself (not the vp), so they can pass the VM to hooks. No more hook args, we dispatch without them. * libguile/vm-engine.h (RUN_HOOK): Dispatch the hook if the trace level is positive (instead of if the hook is there). Don't cache registers on return from the dispatch. * libguile/vm.h: * libguile/vm.c (vm_dispatch_hook): Don't bother with a dynwind; instead decrement the trace level when going into a hook, and if we have a nonlocal exit, the trace level never gets incremented again. Worse is better. (make_vm, scm_vm_trace_level, scm_set_vm_trace_level_x): New concept, trace level. If positive, we run the hooks, otherwise we don't. Should work. Removed scm_vm_trace_frame, I don't think that was the right way to do it. * module/system/vm/vm.scm: Replace vm-trace-frame with vm-trace-level and set-vm-trace-level!; the hooks actually get the frame as an argument now.		2009-12-21 21:57:20 +01:00
