risc-v: support crash(8)

Sort a condition. NFCI.

branches: 1.51.2;
Add ${TOOL_DATE} (Jan-Benedict Glaw)

Add Alpha glue for crash(8).

ddb: New `show all tstiles' command.

bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

crash(8): Add powerpc support.

more -fcommon for sources not ready yet

mostly complete basic port of crash(8) to mips.

tested on mipsel and mips64eb. basic functionality works
on the running kernel, not yet tested on crash dumps.

Restrict LOCKDEBUG support to archs with REALCRASH.
Fix build failure for other archs.

Add primitive LOCKDEBUG support.

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

fix syntax

stack protector issue on sparc

branches: 1.33.2;
for 64 bit mips platforms where we built userland largely as n32 by
default, build a handful of tools as n64 so they work properly.

unfortunately, they're also static as dynamic n64 has a problem.

of these tools pstat is probably the lowest hanging fruit to convert
to sysctl. systat would be close were it not for the netstat screen,
which includes netstat itself.

the rest are difficult to perhaps foolish.


the upside is that netstat, pmap and fstat all work properly now.

enable sparc crash(8) builds.
it's not very stable yet but it's not 100% useless.

branches: 1.31.2;
revert kernhist patch accidentally committed

improve error messages (remove \n, use __func__, etc)

Only define the extra flags for kern_timeout.c

add kern_timeout.c for "show callout"

Build everything on all arm variants

Simplify

Rename NetBSD/hp700 to NetBSD/hppa.

Unfortunately our VCS isn't very helpful here.

make crash traces work on sparc64

Add references to ${_NETBSD_VERSION_DEPENDS} for files that
need to be re-created when the NetBSD version changes. They
will also be re-created when any build settings are changed.

branches: 1.22.2;
Don't advertise the abt/und/irq stack pointers as accessible to crash(8)
when they're not

m68k does not have or need db_machdep.c

revert sparc64 hack

Fix build for sparc64

use -n too, so that we don't get a dup note.

- make this work for arm32
- factor out duplicated ifdefs

Enable build of crash(8) for m86k platforms.

Support crash(8) on hppa.

Remove workaround for old binutils.

branches: 1.13.2;
document non-literal format

Default to -Wno-sign-compare -Wno-pointer-sign for clang.
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.

Share the amd64 and i386 files.
XXX: Is there a better way to get the cpu family?

enable crash(8) for sparc64. it's still sort of minimal and segvs
on some commands, but it sort of works and isn't useless.

replace a non-working make construct with a working one.
now crash only builds unsupported.c on non-x86 systems again.

obsolete DB_AOUT_SYMBOLS. however, we need to leave most of the code
in db_sym.[ch] as it is used by the elf version of crash(8).

i will be cleaning up the db_sym.c code in a follow up commit to avoid
having dead code compiled.

- amd64 support
- fix end of file handling

Create vers.c with -r, there is no point in embedding an ever changing
token that isn't even used.

workaround for MKPIE=yes until binutils-2.20.1 is imported. From Piotr Meyer

Userland now builds and uses terminfo instead of termcap.

OK: core@, jdc@

Avoid -mcmodel=kernel so that we can build in PIC mode.

branches: 1.2.2;
Enable WARNS=4 by default, except for:
cpuctl dumplfs hprop ipf iprop-log kadmin kcm kdc kdigest
kimpersonate kstash ktutil makefs ndbootd ntp pppd quot
racoon racoonctl rtadvd sntp sup tcpdchk tcpdmatch tcpdump

(Mostly third-party applications)

Add crash(8), a utility to diagnose kernel crashes. This is basically
ddb running on crash dumps, but with two notable changes:

- Breakpoints, watches, etc are obviously never going to work so they
are not handled.

- You can pipe output to the shell, e.g. ps | grep foo

Items remaining to be done:

- Port it to architectures other than i386. This isn't difficult, just
a case of making db_disasm.c/db_trace.c or their equivalent compile
and work.

- Make more of the "show" commands work, e.g "show uvmexp".

On aarch64, ddb backtrace can be performed without framepointer by specifying
the /s modifier to the ddb trace command (trace/s, bt/s).
The default is trace with framepointer (same as before).

This allows backtracing even on kernels compiled with -fomit-frame-pointer.

tidy up backtrace from crash(9) on aarch64

- fix to dump trapframe when backtracing from crash(8).
- use db_read_bytes() when reading kernel memory.

Add Alpha glue for crash(8).
