Keyword substitution: kv
Default branch: MAIN

pal_opname(): Make the static buffer for unknown PALcode ops large enough
to hold all possible values.
alpha_print_instruction(): Make this private if not-_KERNEL.

Move alpha/alpha/db_instruction.h -> alpha/include/alpha_instruction.h

Sync with HEAD.

Remove the /I "alternate format" from db_disasm(), which was internally
interpreted as "showregs", whcih would print the values of the registers
at each instruction.  Unfortunately, this was fundamentally broken because
the saved registers accessible to DDB are only valid for the faulting
insn that got us into DDB, and not arbitrary isns that can be examined
from within DDB.

Allow alpha_print_instruction() to be called from outside DDB, and
allow the caller to supply a buffer to contain the pretty-printed
insn string, rather than db_printf() (which is used if there is no
supplied buffer).

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

merge to -current.

Do a minor cleanup of alpha (this will make applying pullups post branching
easier).
u_int{8,16,32,64}_t -> uint{*}_t
Change all old-style definitions to C89 prototypes.
Whitespace cleanup.
Constification in db_disasm.c

- sync with head.
- move sched_changepri back to kern_synch.c as it doesn't know PPQ anymore.

sync with head.

TRUE -> true, FALSE -> false

Replace the Mach-derived boolean_t type with the C99 bool type.  A
future commit will replace use of TRUE and FALSE with true and false.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

fix constification fallout

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

%lz -> db_format_hex()

Sync w/ netbsd-1-5-base.

ANSI'ify.

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.

Handle a few more SPECIAL intructions.

bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch
just for reference purposes.
This commit includes 1.4 -> 1.4.1 sync for kame branch.

The branch does not compile at all (due to the lack of ALTQ and some other
source code).  Please do not try to modify the branch, this is just for
referenre purposes.

synchronization to latest KAME will take place on HEAD branch soon.

Sync w/ -current.

pullup 1.5->1.6 (cgd): BWX instruction emulation and unaligned access

convert to DEC-style register names (but not yet done for
the internal PALcode instruction format structure).

Fix printf format warnings on Alpha.

Update marc-pcmcia branch from trunk.

Add support for disassembling the "integer miscellaneous" opcode subgroup.

Fix an oversight in the last commit.

- Rewrite the functions that provide opcode subfunction names to make it
  easier to add instructions that the disassembler doesn't know about
  (the opcode subfunction number is now printed).
- Add the "amask" and "implver" operate subfunctions.
- Add the "ldbu", "ldwu", "stb", and "stw" major opcodes (BWX instructions).

Update marc-pcmcia branch from trunk.

file db_disasm.c was added on branch marc-pcmcia on 1997-09-06 17:59:38 +0000

Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on
such code for Mach 3's Alpha port.  Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me.  Works, but is still
a little rough around the edges.  Known problems:

- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times.  (Alpha doesn't have hardware
  support for single-stepping, and I'm not entirely convinced the
  MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.
