MD function is just a wrapper around db_stack_trace_cmd() that prints out a backtrace of curthread. Currently, this function is only implemented on i386 and alpha (and the alpha version isn't quite tested yet, will do that in a bit). Other changes: - For i386, fix a bug in the raw frame address case. The eip we extract from the passed in frame address does not match the frame we received. Thus, instead of printing a bogus frame with the wrong eip, go ahead and advance frame down to the same frame as the eip we are using. - For alpha, attempt to add a way of doing a raw trace for alpha. Instead of passing a frame address in 'addr', pass in a pointer to a structure containing PC and KSP and use those to start the backtrace. The alpha db_print_backtrace() uses asm to read in the current PC and KSP values into such a request. Tested on: i386 Requested by: many |
