RevisionDateAuthorComments
 1.40  12-Sep-2019  ryo changes of r1.39 was incomplete. only "examin/m" could handle 'q'.
added support 'r','x','z','d','u', and 'o' with 'q' modifier on 32bit arch.
 1.39  10-Sep-2019  ryo - examin/m displays with splitting by spaces as specified size
- add support 'q' modifier on all arch
- consider endianness
 1.38  10-Sep-2019  ryo Add support for 'p' qualifier for pointer values on examine.
this shows as a pointer with symbol if possible. (e.g. "x/p $sp,10")
 1.37  03-Feb-2019  mrg - add or adjust /* FALLTHROUGH */ where appropriate
- add __unreachable() after functions that can return but won't in
this case, and thus can't be marked __dead easily
 1.36  06-Jun-2015  matt branches: 1.36.18;
Add support for 'q' qualifier for 64-bit values on examine and write.
Align data to long so that the MD parts can use aligned load/stores.
Don't use db_extend but use db_expr_t based expressions.
 1.35  26-May-2011  joerg branches: 1.35.14; 1.35.32;
Introduce DDB_EXPR_FMT and replace the logic around DB_EXPR_T_IS_QUAD.
 1.34  07-Mar-2009  ad branches: 1.34.4; 1.34.6;
Make ddb compile and work in userspace. Mostly this is comprised of three
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.
 1.33  16-Nov-2008  pooka branches: 1.33.4;
more <sys/buf.h> police
 1.32  22-Feb-2007  thorpej branches: 1.32.38; 1.32.42; 1.32.46; 1.32.48; 1.32.52;
TRUE -> true, FALSE -> false
 1.31  22-Feb-2007  matt Fix lossage from boolean_t -> bool and updated x86 bus_dma.
 1.30  16-Nov-2006  christos branches: 1.30.4;
__unused removal on arguments; approved by core.
 1.29  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.28  11-Dec-2005  christos branches: 1.28.20; 1.28.22;
merge ktrace-lwp.
 1.27  01-Jun-2005  drochner branches: 1.27.2;
more constification fallout
 1.26  09-Nov-2003  scw Fix format string warnings for platforms where
sizeof(db_addr_t) > sizeof(long). e.g. ILP32 on sh5.
 1.25  17-May-2003  scw branches: 1.25.2;
On some platforms, sizeof(db_expr_t) > sizeof(long), so add a method
to select the right format string (at compile time) when displaying
variables of type db_expr_t.

This fixes a problem where ddb(4) would only display the low 32-bits
of registers for an ILP32 kernel on SH5, even though registers
(and db_expr_t) are always 64-bits wide.
 1.24  16-May-2003  itojun switch to use strlcpy() from libkern.
 1.23  15-Feb-2002  simonb ANSIfy, KNF.
Make some variables and functions static when not used outside of a module.
Make variables in headers extern.
Delete the unused db_find_watchpoint() function.
 1.22  12-Nov-2001  lukem add RCSIDs
 1.21  24-Feb-2001  cgd branches: 1.21.2; 1.21.4;
#include <systm.h> for string fn prototypes.
 1.20  28-Dec-2000  jmc Add x/m option functionality
 1.19  09-Aug-2000  tv Add two new functions, db_format_radix() and db_format_hex(), which supplant
the former %r and %z nonstandard kprintf strings.
 1.18  25-May-2000  jhawk Interface change: db_printsym() takes a third argument, pr, a function
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.
 1.17  30-Mar-2000  augustss Die, register, die!
