kdb_cmds: new (returning) user questions

Howdy,

I have a few basic questions.

1.  Is there a way to "import" custom kdb commands other than
putting them into kdb_cmds and rebuilding the kernel?

2.  I'd like to be able to "bc all" (or "bca").  or I can put
that into a custom defcmd...  Should I just do the latter?

3.  I often need to use what some debuggers call "step over",
i.e., execute a call instruction and break after it returns,
immediately after the call instruction.  Does kdb already have
this command and I just don't see it?  Currently I just use:

defcmd soc "" "step over call"
  bp %rip+5 # CPU-specific
  go
endefcmd

but that leaves me with (should be temporary) breakpoints that
should be deleted ASAP.  Can I determine what bpnum was used and
then clear it later?  (although I don't know when I would clear it)

4.  Is there a way to print (decode) the CPU flags register so that
I can see which bits (conditions) are set/clear?


Thanks.
