| | | | | | | | | | | | | lwp ID before invoking the underlying target operation. For corefiles, we rely on gdb internals to do this, and it uses the pid as an index, rather than the lwpid, so previously, backtraces for multithreaded core files wasn't working correctly. For processes, we currently use ptrace directly, so fixup that code to also use the pid directly. Discussed With: marcel, davidxu MFC After: 4 days

| | | | | | | | | | | | | | Document all options and general usage. Implement the -a option to bump the annotation_level. This improves the Emacs gud behaviour. You can now supply the following function (defun gud-gdb-massage-args (file args) (cons "-a" args)) (e.g. by evaluating it from the *scratch* buffer) and get the normal jump to the source window when browsing the stack. We should probably eventually supply our own kgdb submode to gud.el.

* Prepare for a subsequent import: If the first letter of the filenamemarcel2004-11-091-35/+43
| | | | | | | | | | | changes, start on a new line. Insertion of a filename will keep the diff limited to the block of filenames that have the same first letter instead of creating a huge diff. While here, move remote.c after the remote-*.c files and move tui.c after the tui-*.c files. This matches the order of ls(1) and makes it easier to compare object files created by a stock gdb(1) build with the list of files we have here. This is a non-functional change only.

* Add the beginnings of kernel debugging support. the kgdb(1) toolmarcel2004-07-2511-0/+1089
| | | | | | | | | | | | | | | | | | | | | is basicly a shell on top of libgdb that knows about kernel threads, kernel modules and kvm(3). As the word "beginnings" implies, not all of the features have been implemented yet. The tool is useful and I'd like feedback on the taken route. The simplest way to debug a kernel core file is: kgdb -n 0 This opens /var/crash/vmcore.0 with the corresponding kernel in the object directory (kernel.debug is used if it exists). Typical things that need to be added are: o Auto loading of kernel modules, o Handling of trapframes so that backtraces can be taken across them, o Some fancy commands to extract useful information out of a core file, o Various (probably many) other things.
* o ps_pd{read|write} and ps_pt{read|write} are obsolete interfacemarcel2004-07-171-22/+2
