and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

jhawk. This callback is used by platform code to manage things like
watchdogs that should be disabled while in ddb. Done as a callback
for processors such as mips that support lots of different systems.
"preserving" implies that the data may be copied and might otherwise
be freed, and that other data in the symbol table or sections of
the kernel might be freed, however there is no mechanism for these
things to take place, so "using" is clearer.
up by name (in .shstrtab) instead of guessing based on section
type (and throwing away the small one). In addition to being cleaner,
multiple symbol tables are no longer and error condition, so
booting netbsd.gdb no longer results in ddb being unable to use
*any* symbols.
<vm/pglist.h> -> <uvm/uvm_pglist.h>
<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.
The "ditto" character is " (double-quote); not , (comma) as
indicated in the manpage; and not ' (single-quote) as indicated
in the man.old -style manpage from which the mdoc manpage was derived.
Some other versions of ddb use single-quote for this feature, and this
part of the code may change again in the near future, but the documentation
now affects reality now.
they
important as db_sym() can be called through printf() rather than
db_printf(), causing a trap as the standard %n usage is invoked.
The DDB-specific %n code should disappear from subr_prf.c soon...
from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).
Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.
Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].
Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.
pointer indicating how to print the symbol. This allows db_printsym()
to called in places where db_printf() is not an appropriate output
function.
While straightforward, apologies in advance if I've introduced any minor
syntax errors; I was unable to test compilation this on all the affected
platforms.
the same name); it searches the symbol table(s) for all symbols matching
a given substring, and prints.
Extremely useful for when you forget that critical symbol name.
Also, with /F support (cf. "ls -F") to print a char indicating the
symbol type.
