is 95370c73b8 Make us pass the full ieeefp except regression test.
XXX This is probably a horrible hack, and wrong. FPU signal handling needs
to be further evaluated.

is f8ce8a3693 Fix my own PR port-m68k/3871, nee port-amiga/3871:
- don't erase FPSR exception bits _after_ doing most of the operations in
fpu_implode(), erase them before doing arith and store operations. This fixes
losing the DZ bit.
- create FPSR_OVFL and FPSR_UNFL bits in fpu_implode(). This showed up when
the first error was fixed.
XXX some more work needs to be done. E.g., creating OPERR together with
OVFL looks bogus, but I'm too tired know to re-check docs; and at least we
pass our own regression tests know.

veego 76371b8a9d include <m68k/db_machdep.h> to get the prototype for kdb_trap if DDB and
DEBUG are defined and add a cast for the second argument to the
kdb_trap call.

thorpej b88b183ab5 Don't have kernel vs. non-kernel versions of _ENTRY(); there's no
reason to omit the .type directive in the kernel case.

veego 78996821fa Move the defines of UPAGES and NPTEPG back to the MD param.h, execpt that
the sun3[x] doesn't use NPTEPG.

is de025de65f Add support for T-racing of emulated instructions. (Yes, gdb uses this.) 1997-06-27 23:32:09 +00:00
is f3efbb406a The recent buserr handler cleanup in the Amiga locore.s made the label
_buserr point to the 68020/030 buserr code _only_. This has broken access
error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.

is 6d6e724440 Reorganize buserr/addrerr stuff, to allow omitting unused code in single-cpu
kernels, at the same time getting rid of up to 3 conditional branches and a
bit over one cacheline fetch (for the 68060; the saving is a bit smaller for
040 and yet smaller for the 020/30).
While we're here, also get rid of an redundant lea (using SP-relative
addressing) and of two redundant pushes.
While we're here, also fix a panic which would tear us down on 68060 machines
if a branch prediction error ever occured.

jtc 8ab87a1df9 fix tipo 1997-05-30 01:34:49 +00:00
jtc 9d04fc8ed1 New zeropage() implementation based on code contributed by Hiroshi Horitomo
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3641.   I changed the code slightly.
Instead of clearing 13 registers (d1-d7,a1-a6) and zeroing 512 bytes per
loop iteration, I clear 8 registers (d1-d7,a1) and zero 256 bytes.  This
reduces the size and complexity of the function.

On the '020, the simpler code is less than 1% slower.  Surprisingly, it
is ~3% faster on the '040.

thorpej ffd2acc819 Minimalistic changes to not make assumptions about how C labels
are handled.  This file's ".s" counterpart must now be pre-processed.
1997-04-25 02:26:04 +00:00
thorpej dcca39c0f1 - Don't make assumptions about how C labels are handled.
- Use PANIC() where appropriate.
1997-04-25 02:22:00 +00:00
thorpej deb6fcac46 Add several common trap vector stubs. Not all of them are here (yet),
but several are.
1997-04-25 01:33:18 +00:00
thorpej 658ce85446 Add several useful macros:
- ENTRY_NOPROFILE() and ASENTRY_NOPROFILE(), similar to ENTRY() and
  ASENTRY(), but without the profiling prologue.
- GLOBAL()/ASGLOBAL() and LOCAL()/ASLOCAL(), for defining global and
  local variables with C and ASM labels.
- BSS()/ASBSS(), for defining items in the BSS segment, with C or
  ASM labels.
- PANIC("panic message") - shorthand for calling panic() from assembly code.
- VECTOR(), ASVECTOR(), VECTOR_UNUSED - shorthand for defining entries
  in the vector table.
Also, change RCSID() to pad out the string to even boundary.

thorpej c739bf6e79 New kcore.h for m68k, includes all possible m68k formats in a self-describing
layout, facilitating sharing libkvm on all m68ks.

NOTE: This changes the crash dump format of all m68k ports that use the
new libkvm!

thorpej 309169617d Factor out a few process manipulation routines found in all m68k

is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
