be2c7f3d13 If we panic inside trap(), Do a stack traceback before printing the trap log. 
Also change the stack-traceback code to avoid having multiple returns
(and thus multiple stack pops) because with gcc -O2 that breaks the
heuristic that a "jr ra" preceding the PC precedes code to push the
current stack frame.  Which breaks stacktrace() before it even
traces past itself :-(.  Use a goto instead.

fb9f07db36 Update MIPS stack backtrace code to trace through locore functions, 
traps, and interrupts  The earlier (4.4bsd) code didn't do the first two, and
got the last one wrong.  Also print some functions (e.g., trap handlers)
by name.  Add hook to use something other than printf() as the output
function, e.g,. for kernel debugging.
Tested with the `native' toolset, but not ELF format kernels.
(i.e., unwinding the $GP register is not tested.)

The stack backtrace code that interprets and unwinds stackframes is still
opaque and stylistically awkward.

b2c7420e5a Fix performance bug in pmax MachFlushDCache(). Old code disabled icache 
and wasn't unrolled. This code runs cached and unrolled, giving an order
of magnitude improvement in some cases (e.g., DMA-capable network devices).
In use at Stanford DSG since late January 1995.

026a077a5d Check in source code actually containing changes in previous log message-- 
fixes to turbochannel-based DECstation interrupt enabling.
(I hate network firewalls that break rsh and remote CVS.)

523e8bccbc Fix hardware interrupt-mask setup in the 5k/240 (3max)+ interrupt handler. 
(A similar fix needs to be applied to the 3min and xine handlers.
This fixes a long-standing problem when booting with a card that
wants to interrupt (e.g., a network interface) would have interrupts
enabled before a handler was set up.

Add interrupt-counting code to model-independent interrupt handler,
and 3max (5k/200) and 3max+ (5k/240) md handlers, for vmstat -i.
Similar changes for 3min and xine are obvious but not done.

Add  code for 5k/240 to read, and latch, the current value of the
IOASIC bus-cycle counter at each timer interrupt.  The latched
counter is needed to accurately interpolate the bus-cycle counter value
as a high-resolution clock.

ef8023a47b Check in changes suggested by Ralph Campbell: update variable names 
to use turbochannel slot numbers, add a couple of extra slots, just
in case.

de42a28a1b - added sunos_machdep.c for sun3, atari, amiga and mac68k. 
- changed machdep.c and trap.c to use struct emul.
- remove ep_setup references.
- added struct emul to all emulations.

9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros 
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
