* added support for XNS networking via Dodo-Nethub
* NetHub connection now optional (only if -nh-host is given); released NetHub-related changes to 'ether.c' to the public domain
* Added file using-dodo-networking-with-maiko.md
Documentation for building and using the Dodo-networking addition to Maiko
* Added support for running Maiko unter cygwin/x86_64-x
* Migrate Addr68k/NativeAlignment{2,4} in Nethub code, move timer/async defines to platform.h
* added missing include <netinet/in.h> for FreeBSD
* updated 'compile-flags' with added flags
* splitted ether.c in 3 (_common, _sunos, _nethub)
* reworks/modifications for nbriggs' pull-request review comments
* addintional additions for nbriggs' pull-request review comments
* get the Lisp packet lengths with 'LispInt2CInt'
* renamed variables in dblwordsSwap to indicate it's about double-words
* fixed wrong preprocessor directive unnoticed by clang
* added networking choice option to cmake build, fix to printf warning
- for cmake specify the networking to use with -DMAIKO_NETWORK_TYPE=<type>
- with <type> one of: NONE, SUN_DLPI, SUN_NIT, NETHUB
- e.g.: cmake .. -DMAIKO_NETWORK_TYPE=NETHUB
* integrated improvement to sendPacket() proposed by nbriggs
* integrated fix for SIGBUS on 32-bit big-endian, provided by nbriggs
* MAIKO_ENABLE_ETHERNET should not be unconditionally set on Solaris systems
* Receiving an ethernet packet is an ether interrupt but not an i/o interrupt.

* Remove code for unsupported Sun display configurations
Initial cleanup removing all code that was #ifdef'd for SUNDISPLAY.
Other SunWindows dependent code may also be removeable
* prropstyle will never be defined with no SunWindows support and therefore no pixrect code
* Remove code that is ifndef NOPIXRECT, since pixrects are part of the obsolete Sun windows code.
There are still traces of pixrect dependent code that could be removed.
This was a machine running SunOS 4, which we no longer support.
It had an odd display controller and a compiler with issues that
required workarounds. Those compiler issues aren't an issue in
today's world, so we don't need to keep the workarounds present
for reference.
It had a bit of inline assembly, but that is still present in
other files for other platforms.
We no longer need to run a separate peephole optimization pass over the
compiler generated or hand-coded assembler for SunOS3 and SunOS4 on 68K or SPARC
We remove the preprocessor symbols and code controlled by them
SUN4_OS4_IL
SUN3_OS3_IL
SUN3_OS4_IL
and SUN3_OS3_OR_OS4_IL
This feature was controlled by the compilation flag `OPDISP`
which would enable some bits of assembler on the x86 (ISC or DOS)
or some other specialized code on SPARC. On SPARC hardware, there
was a special compilation process that would preprocess the code
and generate dispatch tables.
We do this now when this feature is enabled using gcc's computed
gotos feature. This is available in clang and some other compilers.
Notably, it isn't present in Visual Studio.
This doesn't decrease our portability at all as this feature is
optional and it replaces specialized assembler code with C using
compiler extensions (making it cross-platform).
In doing this, we've removed a bunch of related code, however,
it is likely that other pieces yet remain and will be removed
in subsequent commits as we clean things up and refine them.
This feature remains disabled by default for now.
* Delete code related to NATIVETRAN feature.
This was obsolete work that had been done for generating
native code from the bytecode.
ClosesInterlisp/medley#89.
* Remove unused SaveD6.
This removes SYSVSIGNALS as we're always and only using POSIX
signals now.
Some platform differences have been papered over. We used to
only ignore SIGPIPE when using BSD signals, but we now ignore
it all the time.
While the SIGFPE code will now compile, it hasn't been updated
to work on modern OSes fully yet as it will need to enable
the correct FP exceptions.
This flag was for SunOS 3 and 4 on sun3 hardware (68k).
It enabled some unsafe optimizations via assembler. This hasn't
actually been built since the DOS port (since the header for this
was renamed, but the code in `xc.c` wasn't updated).
The optimizations here made assumptions that were specific to the
68k hardware and register allocation. They aren't likely to be
of much use moving forward, and we've got plenty of safe performance
improvements from the last 30 years of hardware advances.
The FSERROR define is on all the time now. It was not controlling
all of the functionality, with many places setting Lisp_errnno
outside of the code controlled by the define.
We don't want to modify emulation code yet as ISC support included
a number of other things, including some i386 code that isn't used
on other platforms, but is still useful as a reference.
This also removes support for the DEC3100 keyboard, but leaves a
constant behind for it as I'm not sure about re-numbering.
[NBriggs: keyboard type numbers are stored within all sysouts. Do not renumber supported keyboards, do not reuse previously used keyboard numbers]
This removes code related to HP9000, HPTIMERBUG, and HPUX defines.
It leaves KB_HP9000 for now as I'm not sure about renumbering
those constants.
This should not impact any of the core emulation code.
