9aece96fc0 Add DDB_NUMSYM option which in addition to the symbolic representation
also prints the actual numerical value of the symbol in question.

Users of addr2line(1) will be less proficient in hex arithmetic as a
consequence.

This amongst other things means that traceback lines change from:
   siointr1(c4016800,c073bda0,0,c06b699c,69f) at siointr1+0xc5
to
   siointr1(c4016800,c073bda0,0,c06b699c,69f) at 0xc062b0bd = siointr1+0xc5

I made this an option to avoid bikesheds.

fe08c21a53 Fix warnings in preparation for adding -Wall -Wcast-qual to the
kernel compile.

    This commit includes significant work to proper handle const arguments
    for the DDB symbol routines.

a1c1e16ada Changes to support -Wall, -Wcast-qual. Had to make physical code changes
in db_lookup() to avoid the *cp = 0 / *cp = ':' combo ( temporary
    nul-terminate-then-restore-original ) on a const char * string.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

3da6ef3c3a Fixed bogus type of valuep in struct db_variable. It was `int *' and
became `long *' for alpha, but should always have been `db_expr_t *'.
Fixed variable types to match.

897cd717a5 Add initial support for the FreeBSD/alpha kernel. This is very much a
work in progress and has never booted a real machine.  Initial
development and testing was done using SimOS (see
http://simos.stanford.edu for details).  On the SimOS simulator, this
port successfully reaches single-user mode and has been tested with
loads as high as one copy of /bin/ls :-).

Obtained from: partly from NetBSD/alpha

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

7d350e7256 Fixed printing of small offsets. E.g., -4(%ebp) is now printed
as -0x4(%ebp) instead of as _APTD+0xffc(%ebp), and if GUPROF is
defined, 8(%ebp) is now printed as 0x8(%ebp) instead of as
GMON_PROF_HIRES+0x4(%ebp).

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

791d77e0dd Get rid of two and a half printf in the kernel.
Add more features to the one remaining to handle the job:
	+	signed quantity.
	#	alternate format
	-	left padding
	*	read width as next arg.
	n	numeric in (argument specified) default radix.

Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.

The warnings from gcc may become more wrong and  intolerable because
of this.

Warning:  I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

058284fceb Completed function declarations and/or added prototypes and/or #includes
to get the prototypes.

Changed some `int's to `boolean_t's.  boolean_t's are ints so they are
hard to distinguish from ints.

Converted function headers to old-style.  ddb is written in K&R1 C
except where we broke it.

7b42c960f8 1) cleaned up after Garrett - fixed more redundant declarations, changed
use of timeout_t -> timeout_func_t in aha1542 and aha1742 drivers.
2) fix a bug in the portalfs that was uncovered by better prototyping -
   specifically, the time must be converted from timeval to timespec
   before storing in va_atime.
3) fixed/added some miscellaneous prototypes

f540b1065a Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles.  This is not
quite complete yet, as `config' doesn't yet do the right thing.  You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
